+PREFATORY NOTE
+
+
+From the best available sources have been gathered the following
+biographical particulars of a remarkable family of astronomers--the
+Herschels.
+
+They will serve to show the young reader how great a pleasure may be
+found in the acquisition of knowledge, and how solid a happiness in
+quietly pursuing the path of duty.
+
+On the value of biography it is unnecessary to insist. It is now well
+understood that we may learn to make our own lives good and honest and
+true, by carefully and diligently following the example of the good and
+honest and true who have gone before us. And certain it is that the
+lessons taught by the lives of the Herschels are such as young readers
+will do well to lay to heart.

+THE STORY OF THE HERSCHELS.
+
+
+
+
+CHAPTER I.
+
+
+Of all the sciences, none would seem to yield a purer intellectual
+gratification than that of Astronomy. Man cannot but feel a sense of
+pleasure, and even of power, when, through the instruments constructed
+by his ingenuity, he finds himself brought within reach, as it were, of
+the innumerable orbs that roll through the domains of space. He cannot
+but feel a sense of pleasure, and even of power, when the telescope
+reveals to his gaze not only the worlds that constitute his own
+so-called Solar System, but the suns that light up the borders of the
+Universe, system upon system, sun upon sun, covering the unbounded area
+almost as thickly as the daisies cover a meadow in spring. He cannot
+but feel a sense of pleasure, and even, of power, when he tracks the
+course of the flashing comet, examines into the physical characteristics
+of the Sun and Moon, and records the various phases of the distant
+planets. But if such be his feeling, it is certainly tempered with awe
+and wonder as he contemplates the phenomena of the heavens,--the beauty
+of the stars, the immensity of their orbits, the regularity with which
+each bright world performs its appointed course, the simplicity of the
+laws which govern its motions, and the mystery which attends its far-off
+existence. It has been, said that "an undevout astronomer is mad;" and
+if Astronomy, of all the sciences, be the one most calculated to gratify
+the intellect, surely it is the one which should most vividly awaken the
+religious sentiment. Is it possible to look upon all those worlds within
+worlds, all those endless groups of mighty suns, all those strange and
+marvellous combinations of coloured stars, all those remote nebulous
+clusters,--to look upon them in their perfect order and government,--to
+consider their infinite number and astonishing dimensions,--without
+acknowledging the fulness of the power of an everlasting God, who
+created them, set them in their appointed places, and still controls
+them? Is it possible to be an astronomer and an atheist? Is it possible
+not to see in their relations to one another and to our own little
+planet an Almighty Wisdom as well as an Almighty Love? Could any
+"fortuitous concourse of atoms" have strewed the depths of space with
+those mighty and beautiful orbs, and defined for each the exact limits
+of its movements? Alas! to human folly and human vanity everything is
+possible; and men may watch the stars in their courses, and delight in
+the beauty of Sun and Moon, and perceive all the wonders of the sunrise
+and all the glories of the sunset, without any recognition in their
+hearts of Him who made them--of Him in whom we and they alike live and
+move and have our being! Yet it is not the less true that only the
+devout and thankful heart can adequately and thoroughly sympathize with
+the love and wisdom and power which are written in such legible
+characters on the face of heaven. Astronomy gives up _all_ its
+treasures only to him who enters upon its study in a reverent spirit. It
+affords the purest intellectual gratification only when its pursuits are
+undertaken with a humble acknowledgment of the littleness of man and the
+greatness of God. Half the wonder, half the mystery of creation is lost,
+when we fail to recognize the truth that it is governed by eternal laws
+springing from an Almighty Intelligence. Take the Creator out of
+creation, and it becomes a hopeless puzzle--a dreary problem, incapable
+of solution. But we restore to it all its brightness, all its beauty,
+all its charm, when we are able to lift up our hearts with the Psalmist
+and to say: "Praise ye the Lord. Praise ye the Lord from the heavens;
+praise him in the heights. Praise ye him, sun and moon: praise him, all
+ye stars of light. Let them praise the name of the Lord: for his name
+alone is excellent: his glory is above the earth and heaven."
+
+And it is to be observed that the soul cannot be satisfied without this
+religious view of Nature. The heavens and the earth are as nothing to
+man, if they do not excite his awe and call forth his thanksgiving. We
+might almost suppose that it is for this purpose that the sea rolls its
+waves on the shore, and the violet smiles by the wayside, and the moon
+floods the night with its silver radiance. As a recent writer has
+observed,[1] the beauty of Nature is necessary for the perfection of
+_praise_; without it the praise of the Creator would be essentially
+weakened; our hearts must be roused and excited by what we see. "It may
+seem extraordinary," adds our authority, "but it is the case, that,
+though we certainly look at contrivance or machinery in Nature with a
+high admiration, still, with all its countless and multitudinous uses,
+which we acknowledge with gratitude, there is nothing in it which raises
+the mind's interest in nearly the same degree that beauty does. It is an
+awakening sight; and one way in which it acts is by exciting a certain
+curiosity about the Deity. In what does God possess character, feelings,
+relations to us?--all unanswerable questions, but the very entertainment
+of which is an excitement of the reason, and throws us upon the thought
+of what there is behind the veil. This curiosity is a strong part of
+worship and of praise. To think that we know everything about God, is to
+benumb and deaden worship; but mystical thought quickens worship, and
+the beauty of Nature raises mystical thought. So long as a man is
+probing Nature, and in the thick of its causes and operations, he is too
+busy about his own inquiries to receive this impress from her; but place
+the picture before him, and he becomes conscious of a veil and curtain
+which has the secrets of a moral existence behind it,--interest is
+inspired, curiosity is awakened, and worship is raised. 'Surely thou art
+a God that hidest thyself.' But if God simply hid himself and nothing
+more, if we knew nothing, we should not wish to know more. But the veil
+suggests that it _is_ a veil, and that there is something behind it
+which it conceals."
+
+[Footnote 1: Professor Mozley, "University Sermons," pp. 145, 146.]
+
+Now, this is the feeling which the study of Astronomy very certainly
+awakens. Every day the astronomer discovers something which quickens his
+curiosity to discover more. Every day he catches new glimpses of the
+Almighty Wisdom, which stimulate his desire for a further revelation.
+And all he learns, and all he anticipates learning, combine to produce
+in him an emotion of awe. What grandeur lies before him in that endless
+procession of worlds--in that array of suns and stars extending beyond
+the limits of the most powerful telescopic vision! How marvellous it is!
+How beautiful! Observe the combination of simplicity with power; note
+how a great principle of "law" underlies the apparent intricacy of
+eccentric and intersecting orbits. And then the field of inquiry is
+inexhaustible. The astronomer has no fear of feeling the satiety of an
+Alexander, when he lamented that he had no more worlds to conquer. What
+Newton said of himself is true of every astronomer,--he is but as a
+child on the sea-shore, picking up a shell here and a shell there, but
+unable to grasp a full conception of the mighty ocean that thunders in
+his ears!
+
+And, therefore, because Astronomy cherishes the feelings of awe and
+reverence and praise, because it inspires a continual yearning after
+additional knowledge, because it reveals to us something of the
+character of God, we conceive that of all the sciences it affords the
+purest intellectual gratification. Certainly it is one of the most
+absorbing. Its attraction seems to be irresistible. Once an astronomer,
+always an astronomer; the stars, we may fancy, will not relax the spell
+they lay upon their votary. He willingly withdraws himself from the din
+and gaiety of social life, to shut himself up in his chamber, and, with
+the magic tube due to the genius of a Galileo, survey with ever-new
+delight the celestial wonders. So was it with Tycho Brahé, and
+Copernicus, and Kepler; so was it, as the following pages will show,
+with that remarkable family of astronomers--astronomers for three
+generations--the HERSCHELS.
+
+
+
+
+CHAPTER II.
+
+
+In the quiet city of Hanover, nearly a century and a half ago, lived a
+professor of music, by name Isaac Herschel, a Protestant in religion,
+though presumably of Jewish descent. He had been left an orphan at the
+early age of eleven, and his friends wished him to adopt the vocation of
+a landscape-gardener; but being passionately fond of music, and having
+acquired some skill on the violin, he left Dresden, his birthplace, in
+order to seek his fortune; wandering from place to place, until at
+Hanover, in 1731, he obtained an engagement in the band of the Guards.
+Soon afterwards he married; and by his wife, Anna Ilse Moritzen, had ten
+children, four of whom died in infancy. Of the others, two--a brother
+and a sister--lived to distinguish themselves by their intellectual
+power; and all true lovers of science will regard with reverence the
+memories of William and Caroline Herschel.
+
+Frederick William Herschel was born on the 15th of November 1738. Like
+his father, he displayed an innate musical ability, which was sedulously
+cultivated and constantly developed; while his general mental training
+was left to the care of the master of the garrison-school. Those who are
+gifted with a love and a capacity for music sometimes show to little
+advantage in other pursuits; but such was not the case with William
+Herschel, who progressed so rapidly in all his studies that the pupil
+soon outstripped the teacher. Although, we are told, four years younger
+than his brother Jacob, the two began French together, and William
+mastered the language in half the time occupied by his senior. His
+leisure time out of school, when not given up to practice on the oboe
+and the violin, was devoted to the acquisition, of Latin and arithmetic.
+
+His father in 1743 was present at the battle of Dettingen; and the
+exposure consequent on a night spent on the rain-soaked battle-field
+afflicted him with an asthmatic complaint and a partial paralysis of
+the limbs, which darkened for years the musician's peaceful household.
+He himself, however, was greatly cheered by the musical proficiency of
+his two sons, and the intellectual refinement of Frederick William. "My
+brothers," says Caroline Herschel, "were often introduced as solo
+performers and assistants in the orchestra of the court; and I remember
+that I was frequently prevented"--she was then a child about five years
+old--"from going to sleep by the lively criticism on music on [their]
+coming from a concert, or conversations on philosophical subjects, which
+lasted frequently till morning, in which my father was a lively
+partaker, and assistant of my brother William by contriving self-made
+instruments." She adds that she often kept herself awake in order to
+listen to their animating remarks, feeling inexpressibly happy in
+_their_ happiness,--an indication of that devoted and unselfish
+affection which afterwards consecrated her whole life. But, generally,
+their conversation branched out into philosophical subjects; and
+father and son argued with so much fervour, that the fond mother's
+interference became necessary,--the immortal names of Leibnitz, Newton,
+and Euler ringing with a clarion-like peal that boded ill for the repose
+of the younger members of the family. "But it seems," says Caroline,
+"that on the brothers retiring to their own room, where they shared the
+same bed, my brother William had still a great deal to say; and
+frequently it happened that, when he stopped for an assent or a reply,
+he found his hearer had gone to sleep; and I suppose it was not till
+then that he bethought himself to do the same. The recollection of these
+happy scenes confirms me in the belief that, had my brother William not
+then been interrupted in his philosophical pursuits, we should have had
+much earlier proofs of his inventive genius. My father," she continues,
+"was a great admirer of astronomy, and had some knowledge of that
+science; for I remember him taking me, on a clear frosty night, into
+the street, to make me acquainted with several of the most beautiful
+constellations, after we had been gazing at a comet which was then
+visible. And I well remember with what delight he used to assist my
+brother William in his various contrivances in the pursuit of his
+philosophical studies; among which was a neatly-turned four-inch globe,
+upon which the equator and ecliptic were engraved by my brother."
+
+ * * * * *
+
+In 1755, the tranquil family circle was broken up--the Hanoverian
+regiment in whose band William and Jacob were engaged having been
+ordered to England. The parting was very sorrowful; for the invalid
+father had derived much support as well as enjoyment from the company of
+his sons. At first, the English experiences of the young Germans were
+somewhat severe. They endured all the pangs of poverty; pangs endured
+with heroic composure, while William relaxed not a whit in his devotion
+to the pursuit of knowledge. Happily, however, his musical proficiency
+attracted the attention of Lord Durham, who offered him the appointment
+of bandmaster to a militia regiment stationed in the north of England.
+In this position he gradually formed a connection among the wealthier
+families of Leeds, Pontefract, and Doncaster, where he taught music,
+and conducted the public concerts and oratorios with equal zeal and
+success. In 1764 he paid a brief but happy visit to his family, much to
+the joy of his faithful sister, Caroline. Returning to England, for
+which country he cherished a strong affection, he resumed his career of
+patient industry, and in 1765 was appointed organist at Halifax. He was
+now in receipt of an income which secured him due domestic comforts, and
+enabled him to remedy the defects of his early education. With the help
+of a grammar and a dictionary he mastered Italian. He also studied
+mathematics and the scientific theory of music, losing no opportunity of
+adding to his stores of knowledge.
+
+In 1766 he obtained the lucrative post of organist to the Octagon Chapel
+at Bath. Increased emoluments, however, brought with them increased
+obligations. He was required to play almost incessantly, either at the
+oratorios or in the rooms at the Baths, at the theatre, and in the
+public concerts. When his sister Caroline joined him, in 1772, she found
+him immersed in his various labours. For the choir of the Octagon
+Chapel he composed anthems, chants, and complete morning and evening
+services. A part of every day was occupied in giving lessons to his
+numerous pupils. In truth, he was one of the busiest men in England;
+yet in all his arrangements he was so methodical that he found time for
+everything--and time, more particularly, for the studies in which his
+soul delighted. His life furnishes an admirable example of what may
+be accomplished by a man with a firm will and a strong purpose, who
+sets before himself an end to be attained, and controls all his efforts
+towards its attainment. He toiled so hard as a musician, because he
+wanted to be something more. Every spare moment of the day, and
+frequently many hours of the night, he gave up to the pursuits which
+were gradually leading him into the path best fitted for his genius.
+The study of mathematics proved but a preliminary to the study of
+optics; and an accident made him once for all an astronomer.
+
+A common two-foot telescope falling into his hands, revealed to him
+the wonders of the heavens. His imagination was inspired by their
+contemplation; with ever-increasing enthusiasm he gazed on the revolving
+planets, on the flashing stars; he determined to fathom more profoundly
+the constellated depths. A larger instrument was necessary, and Herschel
+wrote to London for it; but the price demanded proved far beyond the
+resources of the sanguine organist. What should he do? He was not the
+man to be beaten back by a difficulty: as he could not buy a telescope,
+he resolved to make one; an instrument eighteen or twenty feet long,
+which would reveal to him the phases of the remotest planets. And
+straightway the musician entered on a multitude of ingenious
+experiments, so as to discover the particular metallic alloys that
+reflected light with the greatest intensity, the best means of giving
+the parabolic figure to the mirrors, the necessary degree of polish, and
+other practical details. In his eager pursuit he enlisted the services
+of his loving and intelligent sister. "I was much hindered in my musical
+practice," she writes, "by my help being continually wanted in the
+execution of the various contrivances; and I had to amuse myself by
+making the tube of pasteboard for the glasses which were to arrive from
+London--for at that time no optician had settled at Bath. But when all
+was finished, no one besides my brother could get a glimpse of Jupiter
+or Saturn, for the great length of the tube would not allow it to be
+kept in a straight line. This difficulty, however, was soon removed, by
+substituting tin tubes."
+
+The work went on famously, as might be expected from so much ardour,
+perseverance, and ingenuity. Of a Quaker resident at Bath, the
+musician-astronomer purchased a quantity of patterns, tools, hones,
+polishers, and unfinished mirrors. Every room in the house was converted
+into a workshop. In a handsomely-furnished drawing-room might be seen
+a cabinetmaker constructing a tube and stands of all descriptions;
+while Herschel's brother Alex was engaged in a bedroom in putting up a
+gigantic turning-machine. Meantime, the claims of music could not be
+ignored: there were frequent rehearsals for the public concerts; lessons
+to pupils; the composition of glees and catches, and the like; the
+superintendence of the practice of the chapel choir; and the study of
+sonatas and concertos for public performance. But all the leisure that
+could be made or stolen was occupied in labours which proved their own
+reward. Straight from the concert-platform rushed the musician to his
+workshop, and many a lace ruffle was torn by nails or bespattered by
+molten pitch; to say nothing of the positive danger to which Herschel
+continually exposed himself by the precipitancy of his movements. For
+example: one Saturday evening, when the two brothers returned from a
+concert between eleven and twelve o'clock, William amused himself all
+the way home with the idea of being at liberty to spend the next day,
+except the few hours' duty at chapel, at the turning-bench; but
+recollecting that the tools wanted sharpening, they ran with them
+and a lantern to their landlord's grindstone in a public yard, where,
+very naturally, they did not wish to be seen on a Sunday morning. But
+William was soon brought back by his brother, almost swooning with the
+loss of one of his finger-nails.
+
+This incident took place in the winter of 1775, at a house situated
+near Walcot turnpike, to which Herschel had removed in the summer of the
+previous year. Here, on a grass plot behind the house, he made active
+preparations for the erection of a twenty-foot telescope. So assiduous
+was his devotion to this work, that while he was engaged in polishing
+the mirror, his sister was constantly obliged to feed him by putting his
+victuals into his mouth. Otherwise he would have reduced himself to a
+condition of positive emaciation! Once, when finishing a seven-foot
+mirror, he did not take his hands from it for sixteen consecutive hours;
+for in these days machinery had not been devised as a substitute for
+manual toil. He was seldom unemployed at meals; but at such times
+employed himself in contriving or making drawings of whatever occurred
+to his fertile fancy. Usually his sister Caroline read to him while he
+was engaged at the turning-lathe, or polishing mirrors; choosing such
+books as "Don Quixote," the "Arabian Nights," the novels of Sterne and
+Fielding; and tea and supper were served without any interruption to the
+task in which Herschel was absorbed.
+
+In Miss Herschel's charming letters we find a vivid sketch of the
+family avocations at this period:---
+
+
+ "My brother applied himself to perfect his mirrors, erecting in
+ his garden a stand for his twenty-foot telescope: many trials
+ were necessary before the required motions for such an unwieldy
+ machine could be contrived. Many attempts were made by way of
+ experiment against a mirror before an intended thirty-foot
+ telescope could be completed, for which, between whiles (not
+ interrupting the observations with seven, ten, and twenty-foot,
+ and writing papers for both the Royal and Bath Philosophical
+ Societies), gauges, shapes, weights, &c, of the mirror were
+ calculated, and trials of the composition of the metal were
+ made. In short, I saw nothing else and heard nothing else
+ talked of but about these things when my brothers were
+ together. Alex was always very alert, assisting when anything
+ new was going forward; but he wanted perseverance, and never
+ liked to confine himself at home for many hours together. And
+ so it happened that my brother William was obliged to make
+ trial of my abilities in copying for him catalogues, tables,
+ &c, and sometimes whole papers which were lent [to] him for his
+ perusal. Among them was one by Mr. Michel, and a catalogue of
+ Christian Mayer in Latin, which kept me employed when my
+ brother was at the telescope at night. When I found that a hand
+ was sometimes wanted when any particular measures were to be
+ made with the lamp micrometer, or a fire to be kept up, or a
+ dish of coffee necessary during a night's long watching, I
+ undertook with pleasure what others might have thought a
+ hardship."
+
+The astronomer-musician's patient survey of the heavens was rewarded,
+on the 13th of March 1781, by the discovery of a new planet, situated
+on the borders of our Solar System. In every way this was a discovery
+of signal importance. It broke up the traditional conservatism of
+astronomers, which had almost refused to regard as possible the
+existence of any planets beyond the orbit of Saturn, because for so
+many years none had revealed themselves to the watchful gaze. Men's
+minds were widened, so to speak, at a bound; their conceptions
+strengthened and enlarged; for the discovery of Georgium Sidus--as
+the new planet was designated by its discoverer, in honour of George
+III.--rendered possible and probable the discovery of other planets,
+and thus extended immeasurably the limits of the Solar System. Herschel,
+whose reputation as a musician had hitherto been local, now sprang into
+world-wide fame as an astronomer. George III., who was a true lover of
+science, and not disinclined to bestow his patronage on men and things
+of Hanoverian origin, summoned him to his presence; and was so much
+pleased with his modest and interesting account of the long labours
+which had led to the great result, that, after a brief interval, he
+bestowed upon him an annual pension of three hundred guineas, and a
+residence, first at Clay Hall, and then at Slough.
+
+But before this well-deserved good fortune fell to him, Herschel
+continued his industrious career as both musician and astronomer. During
+the concert season, which lasted five or six months, he had never a
+night disengaged, but was conducting oratorios at Bath or Bristol,
+arranging for public concerts, attending rehearsals, and superintending
+the performances of his choir. As soon as a lull came, the indomitable
+man, assisted by his faithful sister, returned to his astronomical
+pursuits. To gain a fuller and clearer knowledge of the starry worlds
+scattered over the vast fields of space, Herschel from the first had
+seen that instruments of much greater power were necessary than any
+hitherto used by astronomers. He set to work, therefore, on the
+construction of a thirty-foot telescope; the metallic mirror of which
+must, of course, be of proportionate dimensions. This huge mirror was to
+be cast in a mould of loam prepared from horse-dung, of which an
+immense quantity was to be pounded in a mortar, and sifted through a
+fine sieve; an arduous and almost endless task, undertaken by Caroline
+Herschel and her brother Alex. Then a furnace was erected in a back-room
+on the ground-floor; and every preparation having been made, a day was
+set apart for the casting. The day came, and Herschel and his
+collaborateurs looked forward to the consummation of their hopes. The
+metal was placed in the furnace; but, unfortunately, just when it was
+ready for pouring in a molten stream into the mould, it began to leak,
+and both the Herschels, and the caster with his men, were compelled to
+fly from the apartment, the stone flooring exploding, and flying about
+in all directions, as high as the ceiling. The astronomer, exhausted
+with heat and exertion, fell on a heap of brickbats; exhausted, but not
+dismayed. The work was renewed; and a second casting being attempted, it
+proved entirely successful, and a very perfect metal was formed in the
+mould.
+
+
+
+
+CHAPTER III.
+
+
+In August 1782 the Herschels removed to Datchet. Their new home was "a
+large neglected place; the house in a deplorably ruinous condition, the
+garden and grounds overgrown with weeds." Nor were the domestic
+arrangements more favourable. For a fortnight the little family were
+without a female servant; and an old woman, the gardener's wife, showed
+Miss Herschel the shops, where the high prices of every article, from
+coals to butcher's meat, appalled her. But of these inconveniences
+Herschel took no account. Enough for him that he was released from the
+drudgery of teaching, and free thenceforth to devote himself to the
+heavens and their wonders. A man whose thoughts are always with the
+stars can hardly be expected to trouble himself about the price of
+tallow-candles! Were there not capacious stables in which mirrors of
+any size could be ground; and a roomy laundry capable of easy conversion
+into a library, with one door opening on a large lawn, where the "small
+twenty-foot" was to take its stand? Compared with advantages such as
+these, what mattered the scarcity of "butcher's meat"? Herschel
+laughingly assured his sister that they could live on eggs and bacon;
+which, he confidently asserted, would cost next to nothing, now that
+they were really in the country!
+
+And so he settled down to a life of quiet, industry at Datchet; his
+admirable sister being formally adopted as his assistant and secretary.
+Never had master a more devoted, a more enthusiastic, or a more
+intelligent servant! She shared in all his night-watches, with her eye
+constantly on the clock, and the pencil in her hand; with unerring
+accuracy she made all the complex calculations so frequently required;
+she made three or four copies of every observation in separate
+registers, co-ordinating, classifying, and analyzing them. If the
+scientific world, says Arago, saw with astonishment the unexampled
+rapidity with which Herschel's works succeeded one another for many
+years, they were greatly indebted for this affluence of production to
+the affectionate ardour of his sister Caroline. Her enthusiasm never
+failed; her industry knew no check; and her brother's fame was dearer to
+her than life.
+
+In one of her letters she describes with graphic simplicity the
+"interior" at Datchet:--
+
+
+ "I found that I was to be trained for an assistant-astronomer;
+ and by way of encouragement, a telescope adapted for 'sweeping'
+ (or rapidly surveying a wide extent of space), consisting of a
+ tube with two glasses, was given [to] me. I was to 'sweep for
+ comets;' and I see by my journal that I began August 22nd,
+ 1782, to write down and describe all remarkable appearances I
+ saw in my 'sweeps.' But it was not till the last two months of
+ the same year that I felt the least encouragement to spend the
+ starlit nights on a grass-plot covered with dew or hoar-frost,
+ without a human being near enough to be within call. I knew
+ too little of the real heavens to be able to point out every
+ object so as to find it again without losing too much time
+ by consulting the Atlas. But all these troubles were removed
+ when I knew my brother to be at no great distance, making
+ observations with his various instruments on double stars,
+ planets, and the like; and I could have his assistance
+ immediately when I found a nebula, or cluster of stars, of
+ which I intended to give a catalogue. I had the comfort to
+ see," she continues, "that my brother was satisfied with my
+ endeavours to assist him when he wanted another person either
+ to run to the clocks, write down a memorandum, fetch and carry
+ instruments, or measure the ground with poles,--of which
+ something of the kind every moment would occur."
+
+The conscientious care and assiduous industry with which Herschel made
+his measurements of the diameter of the Georgium Sidus (now called
+Uranus), and his interesting observations of other planets, of double
+stars with their coloured light, of cometary and nebulous appearances,
+were truly remarkable; as may be seen by the various papers which
+he wrote at this time for the Royal Society. In addition to all this
+labour, he perfected a twelve-inch speculum of vast magnifying power
+before the spring of 1784; and many hours were spent at the
+turning-bench, as not a night clear enough for observing ever passed
+without the devising of improvements in the mounting and motion of
+the various instruments then in use, or the test and trial of
+newly-constructed "eyepieces," most of which were executed by Herschel's
+own hands. "Wishing to save his time, he began to have some work of that
+kind done by a watchmaker, who had retired from business, and lived on
+Datchet Common; but the work was so bad, and the charges [were] so
+unreasonable, that he could not be employed. It was not till some time
+afterwards, in his frequent visits to the meetings of the Royal Society
+(made in moonlight nights), that he had an opportunity of looking about
+for mathematical workmen, opticians, and founders. But the work seldom
+answered expectation, and it was kept to be executed with improvements
+by Alexander during the few months he spent with us."
+
+ * * * * *
+
+In July 1783 Herschel began his observations with his large twenty-foot
+telescope, though it was in an unfinished state; and his sister watched
+and waited with much apprehension when she knew him to be elevated some
+fifteen feet or more on a temporary crossbeam instead of a safe gallery.
+Here it is needful to explain, perhaps, that these huge astronomical
+telescopes are not used like ordinary glasses, to one end of which the
+observer applies his eye; the objects towards which the tube is directed
+being thrown upon a large mirror, which is attached to it externally
+at some distance from the ground. The observer, therefore, needs to
+be mounted on an elevated platform or gallery, from which he can
+conveniently inspect the mirror. One night, in a very high wind,
+Herschel had scarcely descended from his station before the whole
+apparatus came down; and his sister was in continual apprehension of
+some serious accident. One such, indeed, occurred, and to herself. The
+evening of the 31st of December had been cloudy, but as a few stars
+shone forth about ten o'clock, hurried preparations were made for
+observing. Herschel, standing at the front of the telescope, directed
+his sister to make a certain alteration in the lateral motion, which was
+done by machinery, on which the point of support of the tube and mirror
+rested. At each end of the machine or trough was an iron hook, such as
+butchers use for suspending their joints of meat; and having to run in
+the dark across ground covered a foot deep with melting snow, Miss
+Herschel fell on one of these hooks, which entered her right leg above
+the knee. To her brother's injunction, "Make haste!" she could answer
+only by a pitiful cry, "I am hooked!" He and the workmen hastened
+immediately to her assistance, but they could not disentangle her
+without leaving nearly two ounces of her flesh behind. For some weeks
+she was an invalid, and at one time it was feared that amputation might
+be necessary.
+
+ * * * * *
+
+Not satisfied with the magnifying power of any of the instruments he
+had hitherto constructed, Herschel resolved, in 1784, to attempt a
+forty-foot telescope. Such a work, however, was far beyond his limited
+private resources; and he did not venture to undertake it until promised
+a royal bounty of £2000. Then he removed from Datchet to Clay Hall, Old
+Windsor; and again, in 1786, to Slough, where he finally settled, and
+succeeded in erecting a commodious and well-equipped observatory. "We
+may confidently assert," says Arago, "relative to the little house and
+garden of Slough, that it is the spot of all the world where the
+greatest number of discoveries have been made. The name of that village
+will never perish: science will transmit it religiously to our latest
+posterity."
+
+At Slough, as at Datchet, prevailed the most enthusiastic industry; and
+the house was soon as full of well-ordered labour as a bee-hive. Smiths
+were kept constantly at work on different parts of the new telescopic
+leviathan; and a whole troop of labourers was engaged in grinding the
+tools required for shaping and polishing its mirror. Had not a cloudy or
+moonlight night sometimes intervened, Herschel and his sister must have
+died of sheer exhaustion, for they toiled with unremitting ardour both
+day and night. With the morning came the workpeople, of whom no fewer
+than between thirty and forty were at work for upwards of three months
+together: some employed in felling and rooting out trees, some digging
+and preparing the ground for the bricklayers, who were laying the
+foundation for the telescope. Then there were the carpenter and his men;
+and, meanwhile, the smith was converting a wash-house into a forge, and
+manufacturing complete sets of tools for his own share of the labour.
+In short, the place was at one time a complete workshop for the
+manufacture of optical instruments; and it was a pleasure to enter it
+for the purpose of observing the fervour of the great astronomer, and
+the reverent attention given to his orders.
+
+It is impossible not to refer here to the sisterly devotion of Caroline
+Herschel, who was in every respect worthy of her noble-minded,
+tender-hearted, and enthusiastic brother.
+
+She stood beside him to the last, sharing his labours, brightening his
+life. In the days, says her biographer, when Herschel gave up a
+lucrative career that he might dedicate all his energies to astronomical
+pursuits, it was through her care and thriftiness that he was spared
+from the unrest of pecuniary anxieties. As she had been his helper and
+assistant during his career as a popular musician, so she became his
+helper and assistant when he gave himself up, like the Chaldeans of old,
+to the study of the stars. By dint of a resolute will and a love that
+shrank from no sacrifice or exertion, she acquired such a knowledge of
+mathematics and calculations, mysterious as these generally seem to the
+feminine mind, that she was able to formulate with exactness the result
+of her brother's researches. She never failed to be his willing
+fellow-labourer in the workshop; she helped him to grind and polish his
+mirrors; she stood beside his telescope, in order to record his
+observations, during the dark and bitter mid-winter nights, when the
+very ink was frozen in the bottle. It may be said, without exaggeration,
+that she kept him alive by her care: thinking nothing of herself, she
+lived for him, and him alone. She loved him, she believed in him, she
+aided him with all her heart and all her strength. Her mental powers
+were very considerable; and undoubtedly she might have attained to
+eminence on her own account, for she herself discovered no fewer than
+eight comets. But she shunned self-glorification; she desired to live in
+her brother's shadow; she worked for him, never for herself; and in her
+elevated character no feature more strongly demands our admiration than
+her heroic though unconscious self-denial. Happy the man who has such a
+sister; happy the sister whose brother is worthy of so much devotion! It
+is pleasant to know that William Herschel deserved the love so lavishly
+poured out at his feet; that great as were his achievements in science,
+lofty and broad as was his genius, they were fully sustained and
+ennobled by the beauty and worth of his inner life. Who can contemplate
+their twofold career in all its singleness of purpose, its purity, its
+unselfishness, its sublime disregard of worldly pleasures, without
+emotion? The lessons told by such a life are worth all the moral
+treatises ever written.
+
+To Miss Herschel's diary we again refer, for a glimpse of the
+occupations of her brother and herself at Slough in the first two years
+of their residence. These two years, to use an apt expression of her
+own, were spent in a perfect chaos of business. The garden and workrooms
+swarmed with labourers and workmen--smiths and carpenters speeding to
+and fro between the forge and the forty-foot machinery; and so incessant
+was the vigilance of Herschel, that not a screw-bolt in the whole
+apparatus was fixed except under his eye. "I have seen him," writes his
+sister, "lying stretched many an hour in the burning sun, across the top
+beam, whilst the iron-work for the various motions [of the great
+telescope] was being fixed." At one time no fewer than twenty-four men,
+in relays of twelve each, were engaged in grinding and polishing day and
+night; and Herschel never left them, taking his food without allowing
+himself time to sit down to table.
+
+ "In August 1787," writes the diarist, "an additional
+ man-servant was engaged, who would be wanted at the handles of
+ the motions of the forty-foot,"--that is, to raise or lower it,
+ or move it from side to side, as might be required,--"for which
+ the mirror in the beginning of July was so far finished as to
+ be used for occasional observations on trial. Such a person was
+ also necessary for showing the telescopes to the curious
+ strangers, as by their numerous visits my brother and myself
+ had for some time past been much incommoded. In consequence of
+ an application made through Sir J. Banks to the king, my
+ brother had in August a second sum of £2000 granted for
+ completing the forty-foot, and £200 yearly for the expense of
+ repairs; such as ropes, painting, &c., and the keep and
+ clothing of the men who attended at night. A salary of £50 a
+ year was also settled on me, as an assistant to my brother. A
+ great uneasiness was by this means removed from my mind; for
+ though I had generally (and especially during the last busy six
+ years) been almost the keeper of my brother's purse, with a
+ charge to provide for my personal wants, only annexing in my
+ accounts the memorandum '_For Car_.' to the sums so laid out.
+ When cast up, they hardly amounted to seven or eight pounds per
+ year since the time we had left Bath. Nothing but bankruptcy
+ had all the while been running through my silly head, when
+ looking at the sums of my weekly accounts, and knowing they
+ could be but trifling in comparison with what had been and had
+ yet to be paid in town. I will only add, that from this time
+ the utmost activity prevailed to forward the completion of the
+ forty-foot."
+
+In recognition of his scientific triumphs, the honorary degree of LL.D
+was conferred upon Herschel, in 1786, by the University of Oxford. They
+were triumphs that well merited such a recognition. He had already made
+some important observations on the nature of double stars, on the
+dimensions of the telescopic planets, and had begun his famous
+investigations into the composition of the nebulae,--those clusters of
+stars and nebulous matter which had previously proved such a problem to
+astronomers. The remarkable phenomenon of a periodical change of
+intensity in certain stars, which wax and wane in radiance like a
+revolving light, had also excited his attention. Further, he had entered
+upon the experiments which ultimately showed that the Sun positively
+moves; that in this, as in other respects, the magnificent orb of day
+must be ranged among the stars; that the apparently inextricable
+irregularities of numerous sidereal proper motions arise in great part
+from the displacement of the Solar System; that, in short, the point of
+space toward which Earth and its sister planets are annually advancing,
+is situated in the constellation of Hercules.
+
+"Let us," says a French writer, "to these immortal labours add the
+ingenious ideas that we owe to Herschel on the nebulae, on the
+constitution of the Milky Way, on the Universe as a whole,--ideas which
+almost by themselves constitute the actual history of the formation of
+the worlds,--and we cannot but have a deep reverence for that powerful
+genius that scarcely ever erred, notwithstanding the ardour of its
+imagination."
+
+The ordinary spectator, looking upon the face of the heavens through a
+telescope, had, prior to Herschel's time, felt his curiosity excited by
+the appearance here and there of filmy patches, vague in structure and
+irregular in shape, which, from their resemblance to clouds, received
+the name of _nebulae_. What these were, no astronomer had succeeded in
+defining. It was left for Herschel, with his rare powers of patient and
+discriminating observation, assisted by the more powerful instruments
+which his ingenuity succeeded in constructing, to discern in them
+innumerable groups of worlds, in various stages of formation! A new
+light was thrown upon the history of the Universe. Man was able to
+assist, as it were, at the process of creation, and to watch the
+development of a mass of incoherent matter into a perfect star. This
+alone was a discovery which might well have immortalised the name of
+Herschel.
+
+But we owe to him the elements of our knowledge of the Sun's physical
+constitution. He swept aside the erroneous theories and conjectures
+which had previously prevailed, and guided the astronomical inquirer
+into the right path. He convinced himself, by long and patient
+researches, that the luminous envelope of the great "orb of day" was
+neither a liquid nor an elastic fluid; that it was in certain respects
+analogous to the clouds which wreathe our mountain-summits and fertilize
+our plains; that it floated in the solar atmosphere. Thence he came to
+the conclusion that the Sun has two atmospheres, endowed with motions
+quite independent of each other. An elastic fluid, now known as the
+_photosphere_, is in course of continual formation on the dark rugged
+surface of the solar mass; and rising, on account of its specific
+lightness, it forms the _pores_ in the stratum of reflecting clouds;
+then, combining with other gases, it produces the irregularities or
+furrows in the luminous cloud-region. When the ascending currents are
+powerful, they create those appearances which astronomers designate the
+_nuclei_, the _penumbrae_, the _faculae_.
+
+Such was Herschel's explanation of the mode of formation of the solar
+spots; and allowing it to be well-founded, we must expect to find--what
+is, indeed, the case--that the Sun does not always and regularly pour
+forth equal quantities of light and heat. It is true that Herschel's
+hypothesis has been modified by later astronomers; but his is the credit
+of having directed them into the right course of inquiry and
+observation.
+
+ * * * * *
+
+The physical constitution of the Moon was a subject which also engaged
+the attention of our indefatigable enthusiast. As early as 1780 he
+attempted the measurement of the lunar mountains, and came to the
+conclusion that few of them exceeded 2600 feet in height. Later
+research, however, has proved these figures to be inadequate. Next he
+addressed himself to a study of the lunar volcanoes, three of which he
+declared to be in a state of ignition; two of them apparently on the
+decline, the third still active. He was so convinced of the reality of
+the phenomenon, that on the 20th of April 1787 he wrote:--"The volcano
+burns with greater violence than it did last night." The real diameter
+of the volcanic light he estimated at 16,400 feet. Its intensity he
+described as superior to that of the nucleus of a comet then flashing
+across our system. The objects situated near the crater were fully
+illuminated by the glare of its burning matter.
+
+It may seem strange that, after observations so exact and minute, few
+astronomers now admit the existence of active volcanoes in the Moon. The
+reasons for their incredulity are thus stated:--
+
+The various parts of the Moon do not all reflect with the same
+intensity. Here, that intensity may be dependent on the form;
+elsewhere, on the nature of the materials. Those persons who have
+examined the lunar orb with telescopes, know how very considerable the
+difference arising from these two causes may be,--with how much keener
+and stronger a radiance one point of the Moon will sometimes shine than
+those around it. Well, it would seem to be obvious that the ratio of
+intensity between the brilliant parts and the faint parts must always be
+the same, whatever the origin of the illuminating light. In that portion
+of the lunar sphere which receives the glow and glory of the sun, we
+know that some points exist, the brightness of which is extraordinary
+compared with the feeble flickering gleam of those around them. And
+these same points, when seen in the dim reflection of the Earth, will
+still predominate in intensity over the neighbouring regions. In this
+way Arago and others explain the observations of Herschel, without
+admitting the existence of active volcanoes in the Moon. That volcanoes
+there are, is a familiar fact; but they would seem to have exhausted
+their activity in long-past ages. The lunar surface is now a dreary
+waste of rugged lava and ashes, covered with the matter ejected from
+craters once in a state of furious eruption. The Moon, in fact, is a
+world which has burned itself out. How strange the thought that in a
+far-back period the inhabitants of Earth, had Earth then been inhabited,
+might have seen the glare of countless volcanoes diffused, lurid and
+threatening, over the face of their satellite! How strange the thought
+that the once active fires should all have died away, and the Moon have
+thus been prepared for the better reception and reflection of the solar
+radiance in order to illuminate the nights of Earth!
+
+The planets, needless to say, were the objects of Herschel's assiduous
+attention. Mercury was the one which least interested him; but he
+ascertained the perfect circularity of its disc. With respect to Venus,
+he endeavoured to determine the time of its rotation from 1777. We owe
+to him the discovery of the true shape of the "red planet Mars,"--that,
+like the Earth, it is an oblate spheroid, or flattened at the poles.
+After Piazzi, Olbers, and Harding had discovered the small planets,
+Ceres, Pallas, Juno, and Vesta, he applied himself to the measurement
+of their angular diameters. His researches led him to the conclusion
+that these four new bodies could not properly be ranked with the
+planets, and he proposed to call them Asteroids--a name now generally
+adopted. Since Herschel's time, the number of these minor planets known
+to astronomers has increased to upwards of one hundred.
+
+With respect to Jupiter, our astronomer arrived at some important facts
+in connection with the duration of its rotation. He also made numerous
+observations on the intensities and comparative magnitudes of its
+satellites.
+
+We come next in order to Saturn, the gloomy planet which the ancient
+astrologers regarded with so much dislike. Here, too, we find traces
+of Herschel's labours. Not only has he enlarged our knowledge of its
+equatorial compression, of its physical constitution, and of the
+rotation of its luminous belt or ring, but he added two to the number
+of its satellites. Five only of these were known at the close of the
+seventeenth century; of which Cussiric discovered four, and Huygens one.
+It was universally believed that the subject was exhausted.
+
+But, on the 28th of August 1780, Herschel's colossal tube revealed to
+his delighted gaze a satellite nearer to the Saturnian ring than those
+previously observed. And a few days later, on the 17th of September, a
+seventh and last satellite crossed his field of vision. It was situated
+between the former and the ring; that is, it is the nearest to it of the
+seven.
+
+But the most remarkable of Herschel's achievements was the discovery of
+the planet Uranus, and the detection of its satellites.
+
+On the 13th of March 1781, between ten and eleven o'clock at night, the
+great astronomer was engaged in examining the small stars near H in the
+constellation Gemini, with a seven-foot telescope, bearing a magnifying
+power of two hundred and twenty-seven times. It appeared to him that
+one of these stars was of an unusual diameter; and he came to the
+conclusion, therefore, that it was a comet. It was under this
+denomination that it was discussed at the meeting of the Royal Society.
+But the researches of Herschel at a later period showed that the orbit
+of the new body was circular, and accordingly it was elevated to the
+rank of a planet. As already stated, Herschel named it, in compliment to
+George III., the Georgium Sidus; in this copying the example of Galileo
+with his "Medicaean stars." Afterwards, astronomers christened it
+Herschel, and subsequently Uranus, in conformity with the mythological
+nomenclature of the other planets.
+
+The immense distance of Uranus from our Earth, its small angular
+diameter, and the feebleness of its light, seemed to preclude the hope
+that, if it were attended by satellites of the same dimensions in
+proportion to its own magnitude as those of the satellites of Jupiter
+and Saturn in proportion to _their_ magnitude, they could be descried by
+any human observer. The patient, persevering, reverent temper of
+Herschel took no account, however, of any discouraging or unpropitious
+circumstances. What he did was to substitute for telescopes of the
+ordinary construction the new and gigantic forty-foot tube already
+described; and, thus, with unremitting vigilance and intense zeal, he
+arrived at the discovery (between January 4, 1787, and February 28,
+1794) of the _six_ satellites of Uranus; in other words, he revealed to
+man the completeness of a new system,--a system which will always be
+identified with his name.
+
+ * * * * *
+
+Those singular meteors, the comets, which flash through heaven with long
+trails of light, and of old astonished the nations as if they were
+harbingers of some overwhelming calamity, were also the frequent
+subjects of our astronomer's investigations. He brought some of his fine
+and powerful instruments to bear on a comet discovered by Mr. Pigott in
+1807, and closely and carefully investigated its physical constitution.
+
+The nucleus, or head, was circular and well determined, and evidently
+shone by its own light. Very small stars seemed to grow pale, "to hide
+their diminished heads," when seen through its _coma_ or tail. It is
+true, however, that this faintness may have been only apparent, and due
+to the circumstance of the stars being projected on a luminous
+background. Such was Herschel's explanation. A gaseous medium, capable
+of absorbing sufficient solar radiance to efface the light of some
+"lesser stars," appeared to him to possess in each stratum a sensible
+quantity of matter. Hence it would cause a real diminution of the light
+transmitted, though nothing would indicate the existence of such a
+cause.[1]
+
+[Footnote 1: This conclusion is disputed by many astronomers.]
+
+Herschel examined the beautiful comet of 1811 with equal accuracy.
+"Large telescopes showed him, in the midst of the gaseous head, a rather
+reddish body of planetary appearance, which bore strong magnifying
+powers, and showed no sign of _phase_ (that is, of change of aspect, as
+in the case of the Moon). Hence Herschel concluded that it was
+self-luminous. Yet, if we reflect that the planetary body under
+consideration was not a second in diameter, the absence of a phase,"
+says Arago, "does not appear a demonstrative argument."
+
+The same writer adds:--
+
+ "The light of the head had a bluish-green tint." Was this a
+ real tint, or did the central reddish body, only through
+ contrast, make the surrounding vapour appear to be coloured?
+ Herschel did not examine the question from this point of view.
+
+ "The head of the comet appeared to be enveloped at a certain
+ distance, on the side towards the Sun, by a brilliant narrow
+ zone, embracing about a semicircle, and of a yellowish colour.
+ From the two extremities of the semicircle arose, towards the
+ region away from the Sun, two long luminous streaks which
+ limited the tail. Between the brilliant circular semi-ring and
+ the head, the cometary substance appeared to be dark, of great
+ rarity, and very diaphanous.
+
+ "The luminous self-ring floated: one day it seemed to be
+ suspended in the diaphanous atmosphere by which the head of the
+ comet was surrounded, at a distance of 322,000 English miles
+ from the nucleus.
+
+ "This distance was not constant. The matter of the semi-annular
+ envelope seemed even to be precipitated by slow degrees through
+ the diaphanous atmosphere; finally, it reached the nucleus; the
+ earlier appearances vanished; the comet was reduced to a
+ globular nebula.
+
+ "During its period of dissolution, the ring appeared sometimes
+ to have several branches.
+
+ "The luminous shreds of the tail apparently underwent rapid,
+ frequent, and considerable variations of length. Herschel
+ discerned symptoms of a rotatory movement both in the comet and
+ its tail; a movement which carried unequal shreds from the
+ centre towards the border, and the border towards the centre.
+ On examining at intervals the same region of the tail--the
+ border, for example--sensible changes of length must have been
+ perceptible; which, however, had no reality in them. Herschel
+ thought that both the comet of 1811 and that of 1807 were
+ self-luminous. The second comet of 1811 appeared to him to
+ shine only by borrowed light. It must be acknowledged that
+ these conjectures did not rest on anything demonstrative.
+
+ "In attentively comparing the comet of 1807 with the beautiful
+ comet of 1811, relative to the changes of distance from the
+ Sun, and the modifications resulting thence, Herschel put it
+ beyond doubt that these modifications have something individual
+ in them,--something relative to a special state of the nebulous
+ matter. On one celestial body the changes of distance produce
+ an enormous effect, on another the modifications are
+ insignificant."
+
+We have reproduced these observations by a distinguished French
+astronomer, in order to show the reader what was the nature, and how
+great was the importance, of Herschel's labours, and in how remarkable
+and comprehensive a manner he conducted his survey of the celestial
+phenomena. We now return to our brief narrative of his life.
+
+Such a life, absorbed in tranquil and incessant studies, presents no
+curious, romantic, or surprising incidents. It was the life of a
+reverent, patient, gentle, and devoted man of genius, who dedicated
+himself to the task of making known the "wondrous works of God" to his
+fellow-men, and who in all his social and domestic relations was without
+blot or stain.
+
+In 1788 he married the widow of John Pitt, Esq., with whom he received
+a considerable fortune, and thus for the remainder of his life he was
+enabled to give himself up to his favourite pursuits unembarrassed by
+pecuniary anxieties. His marriage was in every respect a happy one, and
+effectually secured his domestic peace. By his wife he had an only
+son,--the late Sir John Herschel,--who worthily maintained the
+scientific dignity of his name.
+
+It is said, by the highest of all authority, that a prophet is not
+honoured in his own country. But our astronomer was not without the
+reward of his work, even in his lifetime. The University of Oxford
+conferred upon him the illustrious honorary degree of D.C.L. In 1816 he
+received the Guelphic order of knighthood; and in 1820 he was chosen the
+first president of the Astronomical Society.
+
+From his sister's diary we gather a few particulars illustrative of his
+mode of life.
+
+On the 4th of October 1806 she writes:--
+
+
+ "My brother came from Brighton. The same night two parties from
+ the castle [Windsor] came to see the comet, and during the
+ whole month my brother had not an evening to himself. As he was
+ then in the midst of polishing the forty-foot mirror, rest
+ became absolutely necessary after a day spent in that most
+ laborious work; and it has ever been my opinion, that on the
+ 14th of October his nerves received a shock of which he never
+ got the better afterwards; for on that day (in particular) he
+ had hardly dismissed his troop of men, when visitors assembled,
+ and from the time it was dark till past midnight he was on the
+ grass-plot, surrounded by between fifty and sixty persons,
+ without having had time for putting on proper clothing, or for
+ the least nourishment passing his lips.
+
+ "_February 6th, 1807_.--When I came to Slough to assist my
+ brother in polishing the forty-foot mirror, I found my
+ nephew[1] very ill with an inflammatory sore throat and fever.
+
+ "_February 9th_.--Still very ill; and my brother obliged to go
+ on with the polishing of the great mirror, as every arrangement
+ had been made for that purpose.--_Mem_. I believe my brother
+ had reasons for choosing the cold season for this laborious
+ work, the exertion of which alone must put any man into a
+ fever, if he were ever so strong.
+
+ "_February 10th_.--From this day my nephew's health kept on
+ mending.
+
+ "_February 19th_.--My nephew mending, but my brother not well.
+
+ "_February 26th_.--My brother so ill that I was not allowed to
+ see him, and till March 8th his life was despaired of; and by
+ March 10th I was permitted to see him, but only for two or
+ three minutes, as he was not allowed to speak.
+
+ "_March 22nd_.--He (Sir William) went for the first time into
+ his library, but could only remain for a few moments."
+
+ [Footnote 1: Afterwards Sir John Herschel.]
+
+From this dangerous attack Sir William recovered, but thenceforth it
+was clear to his friends that his strength gradually decreased, though
+not his enthusiasm or his industry. He persevered in his life-long
+labours with all his old intellectual force. What failed him was neither
+his tender affections nor his mental powers; but his body refused to
+answer all the demands made upon it by the resolute will,--the sword was
+slowly but surely wearing out the scabbard. Under the date of April 2,
+1819, we meet with an ominous entry in his loving and faithful sister's
+diary:--
+
+
+ "My brother left Slough, accompanied by Lady Herschel, for
+ Bath, he being very unwell; and the constant complaint of
+ giddiness in the head so much increased, that they were obliged
+ to be four nights on the road both going and coming. The last
+ moments before he stepped into the carriage were spent in
+ walking with me through his library and workrooms, pointing
+ with anxious looks to every shelf and drawer, desiring me to
+ examine all, and to make memorandums of them as well as I
+ could. He was hardly able to support himself; and his spirits
+ were so low, that I found difficulty in commanding my voice so
+ far as to give him the assurance he should find on his return
+ that my time had not been misspent.
+
+ "When I was left alone, I found that I had no easy task to
+ perform, for there were packets of writings to be examined
+ which had not been looked at for the last forty years. But I
+ did not pass a single day without working in the library as
+ long as I could read a letter without candlelight, and taking
+ with me papers to copy, which employed me for best part of the
+ night; and thus I was enabled to give my brother a clear
+ account of what had been done at his return. But (May 1) he
+ returned home much worse than he went, and for several days
+ hardly noticed my handiwork."
+
+To this same year of decay and decline (1819) belongs a small slip of
+yellow paper, inscribed with the following lines in a tremulous and
+feeble handwriting, which is jealously preserved by the illustrious
+astronomer's descendants:--
+
+
+ "LINA,--There is a great comet. I want you to assist me. Come
+ to dine, and spend the day here. If you can come soon after one
+ o'clock, we shall have time to prepare maps and telescopes. I
+ saw its situation last night,--it has a long tail.
+
+ "_July 4, 1819_."
+
+Then follows:--
+
+
+ "I keep this as a relic! Every line _now_ traced by the hand of
+ my dear brother becomes a treasure to me.
+
+ "C. HERSCHEL."
+
+We know of nothing more touching in literary history than this noble,
+self-sacrificing, generous affection of the sister towards her eminent
+brother. Such instances of absolute self-denial and all-absorbing love
+elevate our opinion of human nature generally, and prove that something
+of the Divine image lingers in it still.
+
+Herschel was now bordering upon the ripe old age of eighty, and it is no
+wonder that, after a life of incessant study, his strength should daily
+diminish. In 1822 it became painfully evident to his attached relatives
+and friends that the end was not far off; and on the 25th of August he
+passed away to his rest. We owe an account of his last days to his
+sister, but for whose pious care, indeed, very little of his private
+life would have been known, and Herschel could have been judged only
+from the recorded results of his immense labours.
+
+
+ "_May 20th_.--The summer proved very hot; my brother's feeble
+ nerves were very much affected, and there being in general much
+ company, added to the difficulty of choosing the most airy
+ rooms for his retirement.
+
+ "_July 8th_.--I had a dawn of hope that my brother might regain
+ once more a little strength, for I have a memorandum in my
+ almanac of his walking with a firmer step than usual above
+ three or four times the distance from the dwelling-house to the
+ library, in order to gather and eat raspberries, in his garden,
+ with me. But I never saw the like again.
+
+ "The latter end of July I was seized by a bilious fever, and I
+ could for several days only rise for a few hours to go to my
+ brother about the time he was used to see me. But one day I was
+ entirely confined to my bed, which alarmed Lady Herschel and
+ the family _on my brother's account_. Miss Baldwin [a niece of
+ Lady Herschel] called and found me in despair about my own
+ confused affairs, which I never had had time to bring into any
+ order. The next day she brought my nephew to me, who promised
+ to fulfil all my wishes which I should have expressed on paper;
+ he begged me not to exert myself, for his father's sake, of
+ whom he believed _it would be the immediate death if anything
+ should happen to me_."
+
+Afterwards she wrote:--
+
+
+ "Of my dear nephew's advice I could not avail myself, for I
+ knew that at that time he had weighty concerns on his mind.
+ And, besides, my whole life almost has passed away in the
+ delusion that, next to my eldest brother, none but Dietrich was
+ capable of giving me advice where to leave my few relics,
+ consisting of a few books and my sweeper [that is, the
+ seven-foot telescope with which she was accustomed to sweep the
+ heavens for comets]. And for the last twenty years I kept to
+ the resolution of never opening my lips to my dear brother
+ William about worldly concerns, let me be ever so much at a
+ loss for knowing right from wrong."
+
+Miss Herschel proceeds to note that on the afternoons of the 11th, 12th,
+13th, and 14th of August, she, "as usual," spent some hours with her
+brother.
+
+On the 15th she hastened to the accustomed place, where she generally
+found him, with the newspaper which she was to read aloud for his
+amusement. But, instead, she found assembled there several of his
+nearest friends, who informed her that her aged brother had been
+compelled to return to his room. She lost no time in seeking him. He was
+attended by Lady Herschel and his housekeeper, who were administering
+everything which was likely to keep up his failing strength.
+
+Miss Herschel observed that he was much irritated, with the irritation
+natural to old age and extreme bodily feebleness, at his inability to
+grant a friend's request for some token of remembrance for his father.
+No sooner did he see Miss Herschel, the loving companion and
+fellow-worker of so many years, than he characteristically employed her
+to fetch one of his last papers, and a plate (or map) of the forty-foot
+telescope. "But, for the universe," says Miss Herschel, "I could not
+have looked twice at what I had snatched from the shelf; and when he
+faintly asked if the breaking up of the Milky Way[1] was in it, I said,
+'Yes,' and he looked content." I cannot help remembering this
+circumstance; it was the last time I was sent to the library on such an
+occasion. That the anxious care for his papers and workrooms never ended
+but with his life, was proved by his frequent whispered inquiries if
+they were locked and the key safe; of which I took care to assure him
+that they were, and the key in Lady Herschel's hands.
+
+[Footnote 1: The _Via Lactea_, or "Milky Way," had long been supposed to
+consist of a nebulous, vague, luminous matter, but Herschel showed that
+it was really made up of stars and systems of stars.]
+
+After struggling for some thirty minutes against his rapidly increasing
+weakness, the great astronomer, bowed by his burden of years and
+labours, was forced to retire to his bed, with little hope that he would
+ever rise from it again. For ten days and nights his wife and sister
+watched by his side in painful suspense, until, on the 25th of August,
+the end came. Peacefully closed a life which had passed in a peace and
+quietness not often vouchsafed to man.
+
+ * * * * *
+
+Herschel, says a brother astronomer, will never cease to occupy an
+eminent place in the small group of our contemporary men of genius,
+while his name will descend to the most distant posterity. The variety
+and the magnificence of his labours vie with their extent. The more they
+are studied, the more they are admired. For it is with great men as it
+is with great movements in the Arts and in national history,--we cannot
+understand them without observing them from different points of view.
+
+What a brilliant roll of achievements is recalled to the mind by the
+name of William Herschel! The discovery of Uranus, and of its
+satellites; of the fifth and sixth satellites of Saturn; of the many
+spots at the poles of Mars; of the rotation of Saturn's ring; of the
+belts of Saturn; of the rotation of Jupiter's satellites; of the daily
+period of Saturn and Venus; and of the motions of binary sidereal
+systems,--added to his investigations into nebulae, the Milky Way, and
+double, triple, and multiple stars;--all this we owe to his patient, his
+persevering, his daring genius! He may almost be styled the Father of
+Modern Astronomy.
+
+
+
+
+CHAPTER IV.
+
+
+We now propose to furnish a brief sketch of the life of Sir John
+Frederick William Herschel, the only son of Sir William, and not less
+illustrious as a man of science.
+
+He was born at Slough, in the year 1792. Evincing considerable talents
+at a very early age, he received a careful private education under Mr.
+Rogers, a Scottish mathematician of distinguished merit; and afterwards
+was sent to St. John's College, Cambridge, always famous as a nursery of
+mathematical and scientific prodigies! Here he pursued his studies with
+remarkable success, suffering no obstacles to daunt him, and wasting no
+opportunities of improvement. His fellow-collegians regarded him as one
+who would add to the high repute of the college, and rejoiced at the
+brilliant ease with which he passed every examination. In 1813 he took
+his degree of B.A., and consummated a long series of successes by
+becoming "senior wrangler," and "Smith's prizeman;" these being the two
+highest distinctions to which a Cambridge scholar can attain.
+
+In the same year, when he was hardly twenty-one, he published a work
+entitled, "A Collection of Examples of the Application of the Calculus
+to Finite Differences." To our young readers such a title will convey no
+meaning; and we refer to it here only to illustrate the industry and
+careful thought of the young student, which had rendered possible such a
+result.
+
+Returning to Slough, he continued his studies in mathematics, chemistry,
+and natural philosophy, and in various publications exhibited that
+faculty of observation and analyzation, that intelligence and
+scrupulousness in collecting facts, and that boldness in deducing new
+inferences from them, which were characteristic of his illustrious
+father. The subjects he took up were so abstruse, that we could not hope
+to make our readers understand what he accomplished, or how far he
+excelled his predecessors in his grasp and comprehension of them. For
+instance: if we tell them that in 1820 he wrote a paper "On the Theory
+and Summation of Series;" communicated to the Cambridge Philosophical
+Society his discovery that the two kinds of rotatory polarization in
+rock crystal were related to the plagihedral faces of that mineral; and
+issued an able treatise "On Certain Remarkable Instances of Deviation
+from Newton's Tints in the Polarized Tints of Uniaxal Crystals,"--they
+will gain no very distinct idea of the significance or value of these
+researches. Again: it will not be very intelligible to them to be
+informed that, in 1822, he communicated to the Royal Society of
+Edinburgh a paper "On the Absorption of Light by Coloured Media", in
+which he enunciated a new method of measuring the dispersion of
+transparent bodies by stopping the green, yellow, and most refrangible
+red rays, and thus rendering visible the rays situated rigorously at the
+end of the spectrum. But they will understand that these results could
+have been attained only by the most assiduous industry and the most
+unflinching perseverance. And it is on account of this industry and
+this perseverance that we recommend Herschel as an example to our
+readers. They may not make the same progress in science, or achieve the
+same reputation. It is not necessary they should. Humble work is not
+less honourable, if it be done conscientiously, and with a sincere
+desire to do the best that it is in our power to do.
+
+An interesting feature in the younger Herschel's character was his
+loving care for his father's fame. He was ever most anxious that the
+full measure of his services to science should be recognized and
+appreciated. Thus, in 1823, he writes to his aunt:--
+
+
+ "I have been long threatening to send you a long letter, but
+ have always been prevented by circumstances and want of leisure
+ from executing my intention. The truth is, I have been so much
+ occupied with astronomy of late, that I have had little time
+ for anything else--the reduction of those double stars, and the
+ necessity it has put me under of looking over the journals,
+ reviews, &c, for information on what has already been done, and
+ in many cases of re-casting up my father's measures, swallows
+ up a great deal of time and labour. But I have the satisfaction
+ of being able to state that our results in most instances
+ confirm and establish my father's views in a remarkable manner.
+ These inquiries have taken me off the republication of his
+ printed papers for the present.
+
+ "I think I shall be adding more to his fame by pursuing and
+ verifying his observations than by reprinting them. But I have
+ by no means abandoned the idea. Meanwhile, I am not sorry to
+ hear they are about to be translated into German.... I hope
+ this season to commence a series of observations with the
+ twenty-foot reflector, which is now in fine order. The
+ forty-foot is no longer capable of being used, but I shall
+ suffer it to stand as a monument."
+
+ * * * * *
+
+In reference to this famous telescope, we may digress to state that its
+remains have been carefully preserved.
+
+The metal tube of the instrument, carrying at one end the recently
+cleaned mirror of four feet ten inches in diameter, has been placed
+horizontally in the meridian line, on solid piles of masonry, in the
+midst of the circle where the apparatus used in manoeuvring it was
+formerly placed. On the 1st of January 1840, Sir John Herschel, his
+wife, their seven children, and some old family servants, assembled at
+Slough. Exactly at noon the party walked several times in procession
+round the instrument; they then entered the gigantic tube, seated
+themselves on benches previously prepared, and chanted a requiem with
+English words composed by Sir John Herschel himself. Then issuing from
+the tube, they ranged themselves around it, while its opening was
+hermetically sealed.
+
+ * * * * *
+
+In March 1821, the younger Herschel, in conjunction with Sir James
+South, undertook a series of observations on the distances and positions
+of three hundred and eighty double and triple stars, by means of two
+splendid achromatic telescopes of five and seven focal length. These
+were continued during 1822 and 1823, and have proved of great service to
+astronomers.
+
+Having pursued with much zeal the study of optics, and experimented
+largely and carefully on the double refraction and polarization of
+light, he compiled a treatise on the subject for the "Encyclopaedia
+Metropolitana" It has been translated into French by M. Quetelet; and
+both foreign and English men of science have been accustomed to regard
+it as indicating a new point of departure in the important branch of
+science to which it is devoted.
+
+Astronomy, however, became for him, as for his father, the great
+pursuit of his laborious life; and having constructed telescopes of
+singular magnitude and power, he entered upon a study of the Sidereal
+World. In 1825 he commenced a careful re-examination of the numerous
+nebulae and starry clusters which had been discovered by his father, and
+described in the "Philosophical Transactions," fixing their positions
+and investigating their aspects. He devoted eight years to this _magnum
+opus_, completing it in 1832. The catalogue which he then contributed to
+the "Philosophical Transactions" includes 2306 nebulae and
+star-clusters, of which 525 were discovered by himself. While engaged in
+this difficult task, Herschel discovered between three and four thousand
+double stars, which he described in the Memoirs of the Astronomical
+Society. His observations were made with an excellent Newtonian
+telescope, twenty feet in focal length, and eighteen and a half inches
+in aperture; and having obtained, to use his own expression, "a
+sufficient mastery over the instrument," the idea occurred to him of
+making it available for a survey of the southern heavens. Accordingly,
+he left England on the 13th of November 1833, and arrived at Cape Town
+on the 16th of January 1834. Five days later he wrote to his aunt as
+follows:--
+
+
+ "Here we are safely lauded and comfortably housed at the far
+ end of Africa; and having secured the landing and final storage
+ of all the telescopes and other matters, as far as I can see,
+ without the slightest injury, I lose no time in reporting to
+ you our good success _so far_. M----[1] and the children are,
+ thank God, quite well; though, for fear you should think her
+ too good a sailor, I ought to add that she continued sea-sick,
+ at intervals, during the whole passage. We were nine weeks and
+ two days at sea, during which period we experienced only one
+ day of contrary wind. We had a brisk breeze 'right aft' all the
+ way from the Bay of Biscay (which we never entered) to the
+ 'calm latitudes;' that is to say, to the space about five or
+ six degrees broad near the equator, where the trade-winds
+ cease, and where it is no unusual thing for a ship to lie
+ becalmed for a month or six weeks, frying under a vertical sun.
+ Such, however, was not our fate. We were detained only three or
+ four days by the calms usual in that zone, but never _quite_
+ still, or driven out of our course; and immediately on crossing
+ 'the line' got a good breeze (the south-east trade-wind), which
+ carried us round Trinidad; then exchanged it for a north-west
+ wind, which, with the exception of one day's squall from the
+ south-east, carried us straight into Table Bay. On the night of
+ the 14th we were told to prepare to see the Table Mountain.
+ Next morning (_N.B._, we had not seen land before since leaving
+ England), at dawn, the welcome word land' was heard; and there
+ stood this magnificent hill, with all its attendant
+ mountain-range down to the farthest point of South Africa, full
+ in view, with a clear blue ghost-like outline; and that night
+ we cast anchor within the Bay. Next morning early we landed,
+ under escort of Dr. Stewart, M----'s brother, and you may
+ imagine the meeting. We took up our quarters at a most
+ comfortable lodging-house (Miss Robe's), and I proceeded,
+ without loss of time, to unship the instruments. This was no
+ trifling operation, as they filled (with the rest of our
+ luggage) fifteen large boats; and, owing to the difficulty of
+ getting them up from the hold of the ship, required several
+ days to complete the landing. During the whole time (and indeed
+ up to this moment) not a single south-east gale, the summer
+ torment of this harbour, has occurred. This is a thing almost
+ unheard of here, and has indeed been most fortunate, since
+ otherwise it is not at all unlikely that some of the boats,
+ laden as they were to the water's edge, might have been lost,
+ and the whole business crippled.
+
+ [Footnote 1: Herschel married a Miss Stewart in February 1826.]
+
+ "For the last two or three days we have been looking at houses,
+ and have all but agreed for one--a most beautiful place within
+ four or five miles out of town, called 'The Grove.' In point of
+ situation it is a perfect paradise, in rich and magnificent
+ mountain-scenery, and sheltered from all winds, even the fierce
+ south-easter, by thick surrounding woods. I must reserve for my
+ next all description of the gorgeous display of flowers which
+ adorns this splendid country, as well as of the astonishing
+ brilliancy of the constellations, which the calm, clear nights
+ show off to great advantage."
+
+Mr. Herschel settled at Feldhausen, about 142 feet above the sea, and in
+long. 22° 46' 9".11 E., and lat. 33° 58' 26".59 S. Here he entered upon
+his great series of observations of the southern heavens, which he
+continued with unwearied ardour for a period of four years. The results
+were afterwards published, at the cost of the Duke of Northumberland, in
+a work entitled "Results of Astronomical Observations made in
+1834-35-36-37-38, at the Cape of Good Hope." In this superb work, which
+placed its author on an equality with the most brilliant and illustrious
+astronomers, he defined and described 4015 of the nebulae and
+star-groups in the southern hemisphere, and 2995 of the double stars;
+besides entering into a variety of valuable particulars relative to
+Halley's comet, the solar spots, the satellites of Saturn, and the
+measurement of the apparent magnitude of stars.
+
+On his return to England (in 1838) the astronomer received a noble
+welcome. Honours poured in upon him. The Gold Medal of the Astronomical
+Society was conferred upon him for a second time. William IV. had
+previously distinguished him with the Hanoverian order of K.H.; but, on
+the coronation of Queen Victoria, he received a baronetcy; and in 1839
+the University of Oxford made him a D.C.L.
+
+Continuing his career of scientific industry, he issued, in 1849, his
+important and very valuable treatise entitled "Outlines of Astronomy."
+In 1845, he was appointed President of the British Association; and in
+1848, of the Royal Astronomical Society. To his other honours was added
+that of Chevalier of the Prussian order, "Pour la Mérite," founded by
+Frederick the Great, and bestowed at all times with a discrimination
+which renders it a deeply-coveted distinction. Of the academies and
+leading scientific institutions of the Continent and the United States,
+he was also an honorary or corresponding member.
+
+Besides his works on meteorology and physical geography, he published,
+in 1867, an admirable little volume--"Familiar Lectures on Scientific
+Subjects." In this he showed that he could write with as much ease and
+intelligibility for the general public as for the higher order of
+scientific inquirers. His style in this valuable manual of information
+has a charm of its own, and entices the reader into the consideration of
+subjects apparently abstruse. He is earned on from page to page without
+any great mental effort, and finds himself rapidly mastering
+difficulties which he had been accustomed to regard as insuperable.
+
+Let us take the first lecture on "Volcanoes and Earthquakes," and obtain
+a glimpse of Herschel's mode of treatment. He refers to the greater and
+more permanent agencies which affect the configuration of our planet.
+Everywhere, he says, and along every coast-line, we see the sea warring
+against the land, and overcoming it; wearing it and eating it down, and
+battering it to pieces; grinding those pieces to powder; carrying that
+powder away, and spreading it out over its own bottom, by the continued
+effect of the tides and currents. What a scene of continual activity is
+presented by the chalk-cliffs of Old England! How they are worn, and
+broken up, and fantastically sculptured by the influence of winds and
+waters! Precipices cut down to the sea-beach, constantly hammered by the
+waves, and constantly crumbling; the beach itself made of the flints
+outstanding after the softer chalk has been ground down and washed
+away; themselves grinding one another under the same ceaseless
+discipline--first rounded into pebbles, then worn into sand, and then
+carried further and further down the slope, to be replaced by fresh ones
+from the same source. Here the likeness of an old Gothic cathedral, with
+lofty arch, and shapely pinnacle; there the similitude of a mass of
+medieval fortifications, with crumbling battlements and shattered
+towers!
+
+The same thing, the same waste and wear, is going on everywhere, round
+every coast. The rivers contribute their share to the great work of
+change. Look at the sand-banks at the mouth of the Thames. What are
+they, says Sir John Herschel, but the materials of our island carried
+out to sea by the stream? The Ganges carries away from the soil of
+India, and delivers into the sea, twice as much solid substance weekly
+as is contained in the Great Pyramid of Egypt. The Irawaddy sweeps off
+from Burmah sixty-two cubic feet of earth in every second of time, on an
+average Sometimes vast amount of earthy materials is transferred from
+one locality to another by river agency, as is the case in the deltas
+of the Nile and the Mississippi.
+
+These changes operate silently, continuously, and unperceived by the
+ordinary observer; but Nature does not limit herself always and
+everywhere to such peaceful agencies. At times, and in certain places,
+she acts with startling abruptness and extraordinary violence. Let the
+volcano and the earthquake attest the immensity of her power. Let the
+earthquake tell how, within the memory of man, the whole coast-line of
+Chili, for 100 miles about Valparaiso, with the mighty chain of the
+Andes, was hoisted at one blow, and in a single night (November 19,
+1822), from two to seven feet above its former level, leaving the beach
+below the old low-water mark high and dry. One of the Andean peaks
+upheaved on this occasion was the colossal mass of Aconcagua, which
+overlooks Valparaiso, and measures nearly 24,000 feet in height. On the
+same occasion, at least 10,000 square miles of country were estimated as
+having been upheaved; and the upheaval was not confined to the land, but
+extended far away to sea,--which was proved by the soundings off
+Valparaiso and along the coast having been found considerably shallower
+than they were before the shock.
+
+In the year 1819, in an earthquake in India, in the district of Cutch,
+bordering on the Indus, a tract of country more than fifty miles long
+and sixteen miles broad was suddenly raised _ten feet_ above its former
+level. The raised portion still stands up above the unraised, like a
+long perpendicular rampart, known by the name of Ullah Bund, or God's
+Wall.
+
+ * * * * *
+
+With a similar fertility of illustration, Herschel sets before us the
+phenomena of volcanic eruptions and their extraordinary effects.
+
+In a district of Mexico, between the two streams of the Cintimba and the
+San Pedro, on the 28th of September 1789, a whole tract of ground, from
+three to four miles in extent, surged up like a foam-bubble, or the
+swell of a wave, to a height of upwards of 500 feet. Flames, lurid and
+crackling, broke forth over a surface of more than half a square league;
+and the earth, as if softened by heat, was seen to rise and sink like
+the rolling tide. Vast chasms opened in the earth, into which the two
+rivers poured their waters headlong; reappearing afterwards at no great
+distance from a cluster of _hornitos_, or small volcanic cones, which
+sprang out of the mighty mud-torrent that gradually covered the entire
+plain. Wonderful and awful as were these phenomena, they were surpassed
+by the sudden opening of a chasm which vomited forth fire, and red-hot
+stones and ashes, until they accumulated in a range of six large
+mountain masses,--one of which, now known as the volcano of Jorullo,
+attains an altitude of 1690 feet above the ancient level.
+
+In like manner Sir John proceeds to describe an eruption of Mount
+Tomboro, in the island of Sumbawa, the influence of which was felt to a
+distance of 1000 miles from its centre, in strange tremulous motions of
+the earth, and in the clash and clang of loud explosions. He says that
+he had seen it computed that the quantity of ashes and lava ejected in
+the course of this tremendous eruption would have formed three mountains
+of the size of Mont Blanc.
+
+As to the nature of the forces which operate to produce this astounding
+result, Herschel puts forward a theory of singular simplicity and
+directness.
+
+"The origin," he says, "of such an enormous power thus occasionally
+exerting itself, will no doubt seem very marvellous--little short,
+indeed, of miraculous intervention; but the mystery, after all, is not
+quite so great as at first it seems. We are permitted to look a little
+way into these great secrets of Nature; not far enough, indeed, to clear
+up every difficulty, but quite enough to penetrate us with admiration of
+that wonderful system of counterbalances and compensations, that
+adjustment of causes and consequences, by which, throughout all nature,
+evils are made to work their own cure, life to spring out of death, and
+renovation to tread in the steps and efface the vestiges of decay." And
+he finds the clew to the secret, the key of the whole matter, in the
+earth's vast central heat. This it is which produces the convulsions
+that change the terrestrial configuration, and fill the minds of men
+with fear and awe. Conceive of "a sea of fire, on which we are all
+floating, land and sea,"--a boiling, seething, incandescent reservoir in
+the centre of our planet; and the solution of the problem will seem to
+you not difficult. Such a sea would necessarily roll its liquid matter
+to and fro; and the removal of ever so small a portion from one point to
+another on the earth's surface would tend to disturb the equilibrium of
+the floating mass; just as, when a ship is launched into the river, the
+water it displaces is carried to the opposite bank with greater or less
+violence, according to the amount of displacement.
+
+It is impossible, adds Herschel, but that this increase of pressure in
+some places and relief in others must be very unequal in their bearings.
+So that at some point or another our planet's floating crust must be
+brought into a state of strain, and if there be a weak or a soft part a
+crack will at last take place. This is exactly what happened in the
+earthquake which originated the Allah Bund, or God's Wall, in Cutch.
+
+Volcanic eruptions are easily explicable on this principle,--the volcano
+being simply a vent for the passage of heated and molten matter, which
+the elevating pressure of the liquid below tends to eject. It is a
+well-known fact that volcanoes and earthquake-centres are nearly all
+situated on the borders or in the immediate neighbourhood of seas and
+oceans; and the reason would seem to be, that at such positions the
+accumulation of transported matter would necessarily attain its maximum,
+to whatever cause it might be due. Then again, as Herschel points out,
+the eruption of scorite and lava from the mouths of volcanoes, the
+result of the upward movement of the fiery liquid below, compensates in
+some degree for the downward transfer of material by detritus and
+alluvial deposits. Hence it may be inferred that, on the whole, the
+quantity of solid matter above the ocean-level probably remains nearly
+always at the same amount.
+
+ * * * * *
+
+It is with this ease and lucidity that Sir John deals with scientific
+subjects of the greatest importance,--his genius resembling the
+elephant's trunk, which can balance a straw or rend an oak. In private
+life he displayed a simplicity of manner in harmony with the general
+unassumingness of his character. In his books as in society, in society
+as in his books, he was the same,--that is, free from all ostentation,
+free from self-pride, free from the arrogance of superior knowledge, and
+as ready to unbend himself to a child as to discourse with men of
+science.
+
+His career was a tranquil and a prosperous one, and, apart from the
+record of his discoveries and his honours, presents nothing of interest.
+He was peculiarly happy in his domestic relations; and in the wide
+circle of friends attracted by the mingled charm of his intellect and
+manners. A devout Christian, a man of generosity and culture, a
+philosopher of great breadth of view and infinite patience of
+research,--we can place few better or brighter examples before our
+English youth than Sir John Herschel.
+
+
+
+
+CHAPTER V.
+
+
+We could not conclude our notice of this remarkable family without some
+further allusion to its not least remarkable member--Caroline Lucretia
+Herschel.
+
+To her varied accomplishments, her astronomical researches, and, above
+all, to her unwearied and unselfish devotion to her brother William, we
+have already made frequent allusion. She seemed to live for him and in
+him, to live for his fame and prosperity; and she poured out at his feet
+the treasures of an inexhaustible affection. To assist him in his
+labours, at whatever sacrifice, was her sole object in life; and she was
+certainly more careful for his reputation than was he himself. During
+his declining years she was his principal stay and support, and she was
+in daily attendance to note down or to calculate the results of his
+observations. His death was a severe blow to her; but, with
+characteristic courage, she retired to Hanover, gave herself up to
+scientific pursuits, and in comparative solitude spent her later years.
+
+Her biographer writes:--
+
+ "When all was over, her only desire seems to have been to hurry
+ away. Hardly was her brother laid in his grave than she
+ collected the few things she cared to keep, and left for ever
+ the country where she had spent fifty years of her life, living
+ and toiling for him and him only. 'If I should leave off making
+ memorandums of such events as affect or are interesting to me,
+ I should feel like what I am,--namely, a person that has
+ nothing more to do in this world.' Mournful words! doubly
+ mournful, when we know that the writer had nearly half an
+ ordinary lifetime still between her and that grave which she
+ made haste to prepare, in the hope that her course was nearly
+ run. Who can think of her, at the age of seventy-two,
+ heart-broken and desolate, going back to the home of her youth
+ in the fond expectation of finding consolation, without a pang
+ of sympathetic pity? She found everything changed."
+
+_That_, indeed, is to all of us the greatest grief, when we return to
+the home of our youth. It is as if, during the years of our absence, we
+had expected everything to stand as still as in the palace of the
+Sleeping Beauty while the charm rested upon it. We are fain to see the
+trees in their young greenness as when they sheltered our childhood, to
+find the hedgerows blooming with the same violets, to hear the
+mill-stream murmuring with the same music. Time furrows our brows with
+wrinkles, and streaks our hair with silver; our hearts grow colder; our
+minds lose their elasticity and freshness; our friends pass away from
+our side. But still we think to ourselves that in the old scenes all
+things are as they were. We say to ourselves: The bird sings as of old
+in the elm-trees at the garden-foot; the rose-bush blossoms as of old
+against our favourite window.
+
+ "The varying year with blade and sheaf
+ Clothes and re-clothes the happy plains;
+ Here rests the sap within the leaf,
+ Here stays the blood along the veins.
+ Faint shadows, vapours lightly curled,
+ Faint murmurs from the meadows come,
+ Like hints and echoes of the world
+ To spirits folded in the womb."
+
+ * * * * *
+
+But we regain the old familiar places, and, alas! we find that change
+has been as busy with them as with us. The signs of decay are upon the
+trees; the brook has ceased to flow; the rose-bush has withered to the
+ground. There are trees as green and streams as musical and flowers as
+sweet as in our youth; but they are not the streams or flowers or trees
+which delighted us, and to us they can never be as dear. But a worse
+alteration has taken place than any visible in the face of nature. We
+discover that we have lost the old habits, the old capacity of
+enjoyment; and we soon discover that it was the sympathies, the hopes,
+the aspirations of youth which, after all, lent to these early scenes
+their rare and irrecoverable attraction.
+
+And thus it was that Miss Herschel found everything changed. A life of
+fifty years spent in a certain routine and upon certain objects, had
+unfitted her to tread in the old paths. It soon became clear to her that
+all her ideas and feelings had been shaped and influenced in a totally
+different path. More bitter still, we are told, she came to know that in
+her great sorrow and inextinguishable love she was all alone. And
+bitterest of all was the feeling that, in losing her brother she had
+lost the glory of her life, the source of her intellectual enjoyment.
+"You don't know," she wrote to a friend, "the blank of life after
+having lived within the radiance of genius." Yet to live in this
+blankness, and to do the best she could with it, became the work of
+Caroline Lucretia Herschel at the age of threescore years and ten,--an
+age when most of us have already put off our cares and anxieties, but
+when she began to enter on a new life, with new habits, new duties, and
+new associations.
+
+Her interest in astronomical pursuits never slackened, and she watched
+with eagerness the labours and successes of her nephew. The respect paid
+to her in society as a "woman of science" was not unwelcome, though she
+affected to make light of it. "You must give me leave," she wrote to Sir
+John, "to send you any publications you can think of, without mentioning
+anything about paying for them. For it is necessary I should every now
+and then lay out a little of my spare cash in that, for the sake of
+supporting the reputation of being a learned lady; (there is for you!)
+for I am not only looked at for such a one, but even stared at here in
+Hanover!" It was with unaffected modesty she deprecated the honorary
+membership of the Irish Academy, conferred on one who, she said, had
+not for many years discovered even a comet; yet she was by no means
+insensible to the distinction. Every man of scientific eminence who
+visited Hanover visited this aged lady; and her presence in the theatre,
+even in her latest years, was a constant source of attraction. Such was
+the simple frugality of her habits, that she experienced an actual
+difficulty in disposing of her income. She affirmed that the largest sum
+she could spend upon herself was £50 a year; and the annual pension of
+£100, left by her brother, she refused, or else devoted the quarterly or
+half-yearly payment to the purchase of some handsome present for her
+nephew or niece.
+
+Such was Caroline Lucretia Herschel; and as such she was a remarkable
+proof that the rarest womanly gifts of affectionate forethought and
+loving devotion may exist in combination with intellectual strength and
+scientific enthusiasm.
+
+Of the force, keenness, and permanency of her sisterly love, an
+illustration of a pathetic character occurs in a letter which she
+addressed to her nephew, February 27, 1823:--
+
+
+ "I am grown much thinner than I was six months ago: when I look
+ at my hands, they put me so in mind of what your dear father's
+ were, when I saw them tremble under my eyes, as we latterly
+ played at backgammon together."
+
+It has long been the reproach of England that she treats, or rather that
+her Government treats, her men of science, her artists, and her
+litterateurs with a disgraceful parsimony. It would appear from the
+following letter that Sir William Herschel was inadequately rewarded,
+and that his sister felt this keenly:--
+
+
+ "There can be no harm," she says, "in telling my own dear
+ nephew that I never felt satisfied with the support your father
+ received towards his undertakings, and far less with the
+ ungracious manner in which it was granted. For the last sum
+ came with a message that more must never be asked for. (Oh! how
+ degraded I felt, even for myself, whenever I thought of it!)
+ And after all it came too late, and was not sufficient; for if
+ expenses had been out of question, there would not have been so
+ much time, and labour, and expense, for twenty-four men were at
+ times by turns, day and night, at work, wasted on the first
+ mirror, which had come out too light in the casting (Alex more
+ than once would have destroyed it secretly, if I had not
+ persuaded him against it); and without two mirrors, you know,
+ such an instrument cannot be always ready for observing.
+
+ "But what grieved me most was that to the last your poor father
+ was struggling above his strength against difficulties which he
+ well knew might have been removed if it had not been attended
+ with too much expense. The last time the mirror was obliged to
+ be taken from the polisher on account of some obstacle, I heard
+ him say (in his usual manner of thinking aloud on such
+ occasions), 'It is impossible to make the machine act as
+ required without a room three times as large as this.'
+
+ "I must say a few words of apology for the good King (George
+ III.), and ascribe the close bargains which were made between
+ him and my brother to the _shabby, mean-spirited advisers_ who
+ were undoubtedly consulted on such occasions; but they are dead
+ and gone, and no more of them."
+
+In February 1828, the great services which this high-souled woman had
+rendered to astronomical science were fitly rewarded by the presentation
+to her of the Royal Astronomical Society's gold medal,--the greatest
+honour which an astronomer can receive.
+
+Mr. South, himself an astronomer of deserved repute, was charged with
+the duty of presenting the medal; and in the course of his address he
+dwelt on the labours of her brother, and the share she had had in them.
+
+Sir William's first catalogue of new nebulae and clusters of stars, he
+said, amounting in number to one thousand, was compiled with
+observations made from a twenty-foot reflector in the years 1783, 1784,
+and 1785. By the same instrument he was enabled to discover the
+positions of a second thousand of these distant worlds in 1785 to 1788;
+while the places of five hundred others were registered on the celestial
+map between 1788 and 1802. What, we may ask, were the discoveries of
+Columbus compared with these? He revealed to Europe the existence of
+only a single continent; Herschel unfolded to man the mysteries of the
+depths of the heavens.
+
+But, continued Mr. South, when we have thus enumerated the results
+obtained in the course of "sweeps" with this instrument, and taken into
+consideration the extent and variety of the other observations which
+were at the same time in progress, a most important part yet remains
+untold. Who participated in his toils? Who braved with him all the
+experiences of inclement weather? Who shared, and consoled him in, his
+privations? A woman. And who was she? His sister. Miss Herschel it was
+who by night acted as his amanuensis; she it was whose pen conveyed to
+paper his observations as they issued from his lips; she it was who
+noted the various aspects and phenomena of the objects observed; she it
+was who, after spending the still night beside the wonder-exhibiting
+instrument, carried the rough, blurred manuscripts to her cottage at
+daybreak, and by the morning produced a clean copy and register of the
+night's achievements; she it was who planned the labour of each
+succeeding night; she it was who reduced into exact form every
+calculation; she it was who arranged the whole in systematic order; and
+she it was who largely assisted her illustrious brother to obtain his
+imperishable renown.
+
+Miss Herschel's claims to the gratitude of men of science, and to the
+admiration of all who can appreciate the beauty of self-sacrifice, did
+not end here. She was herself an astronomer, and an original observer.
+At times her brother was enabled to dispense with her attendance. You
+would suppose that such leisure nights she would gladly give up to rest.
+Not she. Her brother might, at some unforeseen moment, require her aid,
+and consequently she preferred to be close at hand. A seven-foot
+telescope planted on the lawn helped to while away the hours of waiting;
+and it was to the occupation of these hours that science owed the
+discovery of the comet of 1786, of the comet of 1788, of the comet of
+1791, of the comet of 1793, and of that of 1795, now connected with the
+name of Encke. Many, also, of the nebulae contained in Sir William
+Herschel's catalogues were detected by her keen and accurate gaze during
+these nights of lonely observation. Indeed, as South remarked, when
+looking at the joint-labours of these two enthusiasts, we scarcely know
+whether the warmer praise should be given to the intellectual might of
+the brother or the ardent industry of the sister.
+
+In 1797, continued her eulogist, she presented to the Royal Society a
+catalogue of 560 stars, taken from Flamsteed's observations, the exact
+positions of which had not been previously defined.
+
+Soon after the death of him to whom she had given up so much of her
+life, her best energies, and her ripest faculties, she returned to
+Hanover,--unwilling, however, to relinquish the astronomical researches
+which had been so pure and permanent a source of pleasure. She undertook
+and completed the laborious "reduction" or registration of the places of
+2500 nebulae, down to the 1st of January 1800; thus presenting in one
+view the results of all the observations Sir William Herschel had made
+upon those wonderful bodies, and triumphantly bringing to a close half a
+century of scientific toil.
+
+ * * * * *
+
+We return to Miss Herschel's biography, in order to gather up a few
+particulars of her last years, and to exhibit some of the tenderer
+features of her character.
+
+On the occasion of her nephew's marriage, in 1829, she wrote to him in
+the following terms:--
+
+
+ "MY DEAREST NEPHEW,--I have spent four days in vain endeavours
+ to gain composure enough to give you an idea of the joyful
+ sensation your letter of February 5th has caused me. But I can
+ at this present moment find no words which would better express
+ my happiness than those which escaped in exclamation from my
+ lips, according to Simeon (see St. Luke ii. 29), 'Lord, now
+ lettest thou thy servant depart in peace.'
+
+ "I have now some hopes of passing the few remainder of my days
+ in as much comfort as the separation from the land where I
+ spent the greatest portion of my life, and from all those which
+ are most dear to me, can admit. For, from the description given
+ me of the dear young lady of your choice, I am confident my
+ dear nephew's future happiness is now established.
+
+ "I beg you will give my love to your dear lady, and best
+ regards to all your new connections where they are due, in the
+ best terms you can think of, for I am at present too unwell for
+ writing all I could wish to say.
+
+ "I have suffered much during this severe winter, and have not
+ been able to leave my habitation above three or four times for
+ the last three months; and feel, moreover, much fatigued by
+ sitting eight times within the last ten days to Professor
+ Tiedemann for having my picture taken--which he did at my
+ apartment, and now he has taken it home to finish. I must
+ conclude, for I wish to say a few words to your dear mother. It
+ is now between eleven and twelve, and perhaps you are at this
+ very moment receiving the blessing of Dr. Jennings; in which I
+ most fervently join by saying, 'God bless you both!'"
+
+Though eighty-three years old, Miss Herschel retained all her old powers
+of memory; and in a letter to her new niece, Lady Herschel, written in
+1833, she narrated some amusing reminiscences of her nephew's early
+childhood.
+
+He was only in his sixth year, she said, when she was separated for a
+while from the family circle. But this did not hinder "John" and her
+from remaining the most affectionate friends, and many a half or whole
+holiday he spent with her, devoting it to chemical experiments, in which
+all kinds of boxes, tops of tea-canisters, pepper-cruets, tea-cups, and
+the like, served for the necessary vessels, and the sand-tub furnished
+the matter to be analysed. Miss Herschel's task was to prevent the
+introduction of water, which would have produced havoc on her carpet.
+For his first notion of building, "John" was indebted to the affection
+of his aunt, who, on his second or third birthday, lifted him in the
+trenches to lay the south corner-stone of the building which was added
+to Sir William's original house at Slough. On further reflection, she
+felt convinced that this incident occurred in the second year of her
+nephew's age, for she remembered being obliged to use "a deal of
+coaxing" to make him part with the money he was to lay on the
+comer-stone.
+
+About the same time, when she was sitting near him one day, listening to
+his prattle, her attention was drawn to his repeated and formidable
+hammering. On investigating into its object, she found that it was the
+continuation of the labour of many days, during which he had undermined
+the ground about the corner of the house, had entirely removed the
+corner-stone, and was zealously toiling to overthrow the next! His aunt
+gave the alarm, and old John Wiltshire, a favourite carpenter, ran to
+the spot, exclaiming, "Heaven bless the boy! if he is not going to pull
+the house down!"
+
+ * * * * *
+
+In 1834, Sir John, as already stated, made a voyage to the Cape of Good
+Hope, in order to undertake a series of observations of the southern
+heavens. His aunt had now reached the ripe old age of eighty-four, an
+age attained by few,--and when attained, bringing with it in almost
+every case a painful diminution of physical energy, and a corresponding
+decline in mental force. But such was not the case with this remarkable
+woman. She still continued an active correspondence with her nephew, and
+manifested the liveliest interest in all his movements. It is
+astonishing to mark the vivacity and clearness of the letters she wrote
+at this advanced period of her life. Thus, on the 1st of May 1834, she
+writes to Sir John:--
+
+
+ "Both yourself and my dear niece urged me to write often, and
+ to write always twice; but, alas! I could not overcome the
+ reluctance I felt of [at] telling you that it is over with me
+ for getting up at eight or nine o'clock, dressing myself,
+ eating my dinner alone without an appetite, falling asleep over
+ a novel (I am obliged to lay down to recover the fatigue of the
+ morning's exertions), awaking with nothing but the prospect of
+ the trouble of getting into bed, where very seldom I get above
+ two hours' sleep. It is enough to make a parson swear! To this
+ I must add, I found full employment for the few moments, when I
+ could rouse myself from a melancholy lethargy, to spend in
+ looking over my store of astronomical and other memorandums of
+ upwards of fifty years' collecting."
+
+Later in the year she writes:--
+
+
+ "I know not how to thank you sufficiently for the cheering
+ account you give of the climate agreeing so well with you and
+ all who are so dear to me, and that you find all about you so
+ agreeable and comfortable;... so that I have nothing left to
+ wish for but a continuation of the same, and that I may only
+ live to see the handwriting of your dear Caroline, though I
+ have my doubts about lasting till then, for the thermometer
+ standing 80° and 90° for upwards of two mouths, day and night,
+ in nay rooms (to which I am mostly confined), has made great
+ havoc in my brittle constitution. I beg you will look to it
+ that she learns to make her figures as you find them in your
+ father's MSS., such as he taught me to make. The daughter of a
+ mathematician must write plain figures.
+
+ "My little grand-nephew making alliance with your workmen shows
+ that he is taking after his papa. I see you now in idea,
+ running about in petticoats among your father's carpenters,
+ working with little tools of your own; and John Wiltshire (one
+ of Pitt's men, whom you may perhaps remember) crying out, 'Dang
+ the boy, if he can't drive in a nail as well as I can!'
+
+ "I thank you for the astronomical portion of your letter, and
+ for your promise of future accounts of uncommon objects. It is
+ not _clusters of stars_ I want you to discover in the body of
+ the Scorpion [the astronomical sign, so called], or thereabout,
+ for that does not answer my expectation, remembering having
+ once heard your father, after a long, awful silence, exclaim,
+ 'Hier ist wahrhaftig ein loch ein Himmel!' [Here, indeed, is a
+ great gap in Heaven!], and, as I said before, stopping
+ afterwards at the same spot, but leaving it unsatisfied."
+
+These extracts may seem trivial to some of our readers, but they are not
+so, rightly considered. They illustrate the wonderful mental vivacity of
+their venerable writer, and in this respect are useful; but still more
+useful in showing how cheerfully she bore the burden of her years, and
+with what intellectual serenity she looked forward to her end.
+
+We own that the lives of the Herschels are what the world would call
+uneventful. The discovery of a new planet, or of the orbit of a star,
+seems less romantic to the vulgar taste than the slaughter of ten
+thousand men on a field of battle. It will seem to the unthinking that
+the victorious general or the daring seaman, the leader of a forlorn
+hope, or the captain who goes down with his sinking ship, affords an
+example worthier of imitation than the patient, watchful, enthusiastic
+astronomer or his devoted sister. _His_, they will say, was a noble
+life. Be it so; but every life is noble which is spent in the path of
+duty. Do what comes to your hand to do with all honesty and
+completeness, and you will make _your_ life noble. Subdue your passions,
+master your evil thoughts, observe the laws of temperance and purity, be
+truthful, be firm, be honest, and keep ever before you the law of Christ
+as the law of your daily work, and you will make _your_ life noble. We
+cannot all be great commanders or daring captains, we cannot all be
+distinguished men of science; but we can all be righteously-living men,
+endeavouring to raise others by our example, and it is a higher aim to
+live purely than to live successfully. We cannot all command the
+success, just as we do not all enjoy the intellectual powers, of a
+Herschel; but we can emulate the industry and perseverance of the
+astronomer, we can copy the devoted affection and self-denial of his
+sister. The sorriest mistake of which men can be guilty,--yet it is a
+mistake which has clouded many lives,--is to suppose that duty is less
+imperative in its claims on the humble and unknown than on men raised or
+born to eminent position. Let it be understood and remembered that each
+one of us can rise to a standard of true heroism, by cultivating the
+graces of the Christian character, and doing the work which God has
+appointed.
+
+ * * * * *
+
+Sir John Herschel returned to England in 1838, and in July of the same
+year he and his little son paid a visit to Miss Herschel. It is
+characteristic that her intense anxiety as to the proper treatment of
+her little grand-nephew--his sleep, his food, his playthings--greatly
+disturbed her peace. "I rather suffered him," she writes, "to hunger,
+than would let him eat anything hurtful; indeed, I would not let him eat
+anything at all unless his papa was present." Her biographer remarks,
+that great as was her joy to see once more almost the only living being
+upon whom she poured some of that wealth of affection with which her
+heart never ceased to overflow, yet it was on the disappointments and
+shortcomings of those few days, those precious days, that she chiefly
+dwelt; and the abrupt termination of her nephew's visit filled her with
+the deepest sorrow. With the generous, but, as it proved, mistaken
+intention of sparing her feelings, her nephew left without informing her
+beforehand of the exact time of his departure, simply bidding her
+good-night prior to his return to his inn. Great was her distress when
+she found that he and his son had quitted Hanover at four o'clock on the
+following morning.
+
+Her introduction to her grand-nephew, as described by his father, Sir
+John, was exceedingly quaint:--
+
+ "Now, let me tell you how tilings fell out. Dr. Groskopff took
+ Willie with him to Aunty, but without saying who he was. Says
+ she, 'What little boy is that?' Says he, 'The son of a friend
+ of mine. Ask him his name.' However, Willie would not tell his
+ name. 'Where do you come from, little fellow?' 'From the Cape
+ of Good Hope,' says Willie. 'What is that he says?' 'He says he
+ comes from the Cape of Good Hope.' 'Ay! and who is he? What is
+ his name?' 'His name is Herschel.' 'Yes,'says Willie. 'What is
+ that he says?' 'He says he comes from the Cape of Good Hope.'
+ 'Ay! and who is he? What is his name?' 'His name is Herschel.'
+ 'Yes,' says Willie, 'William James Herschel.' 'Ach, mem Gott!
+ das nicht möglich; ist dieser kleines neffeu's sohn?' And so it
+ all came out; and when I came to her all was understood, and we
+ sat down and talked as quietly as if we had parted but
+ yesterday."
+
+ * * * * *
+
+In a letter which she wrote to Lady Herschel in 1838, we find some
+reminiscences of her early years. She says that when, at the age of
+twenty-two, she first visited England, there was no kind of ornamental
+needle-work, knitting, plaiting hair, stringing beads and bugles, and
+the like, of which she did not make samples by way of mastering the art.
+As she was the only girl, and consequently the Cinderella, of the
+family, she could not find time, however, for much self-improvement. She
+was not, for instance, a skilled musician, but she was able to play the
+second violin part of an overture or easy quartette. And it is worth
+notice that the Herschels were something more than astronomers only.
+Both Sir William and his son, great as they were in their special
+department of science, took care to cultivate their minds generally;
+were mathematicians, chemists, geologists, and men of letters. And here
+is a lesson for our younger readers. The mind should always be diverted
+towards one particular object; it should be the aim of everybody to
+attain towards supreme excellence, if possible, in some one pursuit. On
+the other hand, he should gather knowledge, more or less, in every
+field, so as to avoid narrowness of view and poverty of idea.
+Versatility does not necessarily mean superficiality; we may know much
+of many things, and more of one thing. A man who is only a botanist,
+shuts himself out from all the truest and deepest pleasures of
+knowledge. It may be very clever for a violinist to play on a single
+string; but he must play on _all_, if he would bring out the full
+harmonies of his instrument, and do justice to its extraordinary powers.
+
+ * * * * *
+
+Miss Herschel's enjoyment of life, which, when not carried to an excess,
+is a Christian duty, continued to the very last. When she was in her
+ninetieth year, she rose as usual every day, dressed, ate, drank, rested
+on her sofa, read and conversed with her numerous visitors; still
+taking an interest in science and literature, even in public affairs,
+and still occupying herself with all that concerned the evergrowing
+reputation of her nephew. Of course, she could not escape the
+infirmities of old age, but by cheerfulness and patience she did her
+best to alleviate them. In recalling incidents of her early life, she
+frequently gave evidence of her good-humoured contentment. In 1840,
+writing to her niece, she refers to an incident which occurred in the
+early part of the forty-foot telescope's existence, when "God save the
+King" was sung in it by her brother and his guests, who rose from the
+dinner-table for the purpose, and entered the tube in procession. She
+adds that among the company were two Misses Stows, one of whom was a
+famous pianoforte player; some of the Griesbachs (well-known musicians),
+who accompanied on the oboe, or any instrument they could get hold of;
+and herself, who was one of the nimblest and foremost to get in and out
+of the tube. "But now," she adds, "lack-a-day! I can hardly cross the
+room without help. But what of that? Dorcas, in the _Beggar's Opera_,
+says, 'One cannot eat one's cake and have it too!'"
+
+She relates, in the same letter, a curious anecdote of the old and
+celebrated tube. Before the optical apparatus was finished, many
+visitors took a pleasure in walking through it,--among the rest, on one
+occasion, King George III. and the Archbishop of Canterbury. The latter
+following the king, and finding it difficult to proceed, his majesty
+turned and gave him his hand, saying, "Come, my Lord Bishop; I will show
+you the way to heaven!"
+
+Then, with that astonishing memory of hers, which kept its greenness
+until the very last, she notes that this occurred on August 17, 1787,
+when the King and Queen, the Duke of York, and some of the princesses
+were of the company.

+
+From another letter we take a lively little picture of a Christmas in
+Hanover:--
+
+She had been told that keeping Christmas in the German sense was coming
+to be very general in England; but her shrewd, practical turn of mind
+induced her to hope that the English would never go "such lengths in
+foolery." At Hanover, she wrote, the tradespeople had been for many
+weeks in full employ, framing and mounting the embroideries of the
+ladies and girls of all classes; of _all_ classes, for not a folly or
+extravagancy existed among the great but it was imitated by the little.
+The shops were beautifully lighted up by gas, and the last three days
+before Christmas all that could tempt or attract was exhibited in the
+market-places in booths lighted up in the evening, whither everybody
+hastened to gaze and to spend their money. Cooks and housemaids
+presented one another with knitted bags and purses; the cobbler's
+daughter embroidered "neck-cushions" for her friend the butcher's
+daughter. These were made up by the upholsterer at great expense, lined
+with white satin; the upper part, on which the back rested, being
+wrought with gold, silver, and pearls.

+
+But we must no longer delay the reader by our gossip. Enough has been
+said to illustrate the character of a remarkable woman, and of those
+features of it--her cheerfulness, her patience, her industry, her
+devoted affection, her unselfishness--which all of us may be the better
+for studying and imitating. Our limits compel us to draw our simple
+narrative to a close, and we must pass over the delight with which she
+received and read Sir John Herschel's great work, "Cape
+Observations,"--a noble monument of the perseverance and strenuous
+labour of genius; but of twofold interest to her, because it not only
+testified to the eminent qualities of her nephew, but brought to a noble
+conclusion the vast undertaking of that nephew's father and her own
+beloved brother--the survey of the nebulous heavens.
+
+A letter written by her friend Miss Becksdorff, on the 6th of January
+1848, describes Caroline Herschel's last days:--
+
+
+ "Her decided objection to having her bed placed in a warmer
+ room had brought on a cold and cough; and so firm was her
+ determination to preserve her old customs, and not to yield to
+ increasing infirmities, that when, upon her doctor's positive
+ orders, I had a bed made up in her room, before she came to sit
+ in it one day, it was not till two o'clock in the night that
+ Betty could persuade her to lie down in it. Upon going to her
+ the next morning, I had the satisfaction, however, of finding
+ her perfectly reconciled to the arrangement; she now felt the
+ comfort of being undisturbed, and she has kept to her bed ever
+ since. Her mental and bodily strength is gradually declining.
+ But a few days ago she was ready for a joke. When Mrs. Clarke
+ told her that General Halkett sent his love, and 'hoped she
+ would soon be so well again that he might come and give her a
+ kiss, as he had done on her birthday,' she looked only archly
+ at her, and said, 'Tell the general that I have not tasted
+ anything since I liked so well.' I have just left her, and upon
+ my asking her to give me a message for her nephew, she said,
+ 'Tell them I am good for nothing,' and went to sleep again."
+
+On the 9th of January 1848 she breathed her last, passing away with a
+Christian's tranquillity.[1]
+
+[Footnote 1: The particulars recorded in the foregoing pages are chiefly
+taken from Mrs. John Herschel's very interesting "Memoir and
+Correspondence of Caroline Herschel."]
+
+ * * * * *
+
+Her body was followed to the grave by many of her relatives and friends,
+the royal carriages forming part of the funeral procession. The coffin
+was adorned with garlands of laurel and cypress and palm branches, sent
+by the Crown-Princess from Herrnhausen; and the service was conducted in
+that same garrison-church in which, nearly a century before, she had
+been christened, and afterwards confirmed. And, as proving her love and
+fidelity to the last, in her coffin were placed, by her express desire,
+"a lock of her beloved brother's hair, and an old, almost obliterated
+almanac that had been used by her father."

+
+May our readers be induced, by their perusal of these pages, to emulate
+the Herschels--brother, sister, nephew--in all the bright and lovely
+qualities that ennoble life; in their fixity of purpose, their elevation
+of thought, their purity of character, their self-denial, their
+industry, their hopefulness, and their faith!
+
+ [The following inscription is engraved on Miss Herschel's tomb.
+ It begins: "Hier ruhet die irdische Hülle von CAROLINA
+ HERSCHEL, Geboren zu Hannover den 16ten Marz 1750, Gestorben,
+ den 9ten Januar 1848." But, for the convenience of our young
+ readers, we give it in English:--
+
+ HERE RESTS THE EARTHLY CASE OF
+ C A R O L I N E H E R S C H E L.
+ BORN AT HANOVER, MARCH 10, 1750.
+ DIED JANUARY 9, 1848.
+
+ "The eyes of her now glorified were, while here below, directed
+ towards the starry heavens. Her own discoveries of comets, and
+ her share in the immortal labours of her brother, William
+ Herschel, bear witness of this to succeeding ages.
+
+ "The Royal Irish Academy of Dublin, and the Royal Astronomical
+ Society of London, enrolled her name among their members.
+
+ "At the age of 97 years 10 months, she fell asleep in calm
+ rest, and in the full possession of her faculties; following
+ into a better life her father, Isaac Herschel, who lived to the
+ age of 60 years, 2 months, 17 days, and has lain buried not far
+ off since the 29th of March 1767."
+
+ This epitaph was mainly written by Miss Herschel herself, and
+ the allusion to her brother is characteristic.]
