Tacitus took as a motto: "To say nothing false, to omit nothing true."
Our colleague contented himself in society with the first half of the precept. Never did mockery, bitterness, or severity issue from his lips.
His manners were a medium between those of Lacaille and the manners of another academician who had succeeded in not making a single enemy, by adopting the two axioms: "Every thing is possible, and everybody is in the right."
Crebillon obtained permission from the French Academy to make his reception discourse in verse. At the moment when that poet, then almost sixty years of age, said, speaking of himself,
"No gall has ever poisoned my pen,"
the hall reechoed with approbation.
I was going to apply this line by the author of _Rhadamistus_ to our colleague, when accident offered to my sight a pa.s.sage in which Lalande reproaches Bailly for having swerved from his usual character, in 1773, in a discussion that they had together on a point in the theory of Jupiter"s Satellites. I set about the search for this discussion; I found the article by Bailly in a journal of that epoch, and I affirm that this dispute does not contain a word but what is in harmony with all our colleague"s published writings. I return therefore to my former idea, and say of Bailly, with perfect confidence,
"No gall had ever poisoned his pen."
Diffidence is usually the trait that the biographers of studious men endeavour most to put in high relief. I dare a.s.sert, that in the common acceptation, this is pure flattery. To merit the epithet of diffident, must we think ourselves beneath the compet.i.tors of whom we are at least the equals? Must we, in examining ourselves, fail in the tact, in the intelligence, in the judgment, that nature has awarded us, and of which we make so good a use in appreciating the works of others? Oh! then, few learned men can be said to be diffident. Look at Newton: his diffidence is almost as celebrated as his genius. Well, I will extract from two of his letters, scarcely known, two paragraphs which, put side by side, will excite some surprise; the first confirms the general opinion; the second seems with equal force to contradict it. Here are the two pa.s.sages:
"We are diffident in the presence of Nature."
"We may n.o.bly feel our own strength in the face of man"s works."
In my opinion, the opposition in these two pa.s.sages is only apparent; it will he explained by means of a distinction which I have already slightly indicated.
Bailly"s diffidence required the same distinction. When people praised him to his face on the diversity of his knowledge, our colleague did not immediately repel the compliment; but soon after, he would stop his panegyrist, and whisper in his ear with an air of mystery: "I will confide a secret to you, pray do not take advantage of it: I am only a very little less ignorant than another man."
Never did a man act more in harmony with his principles. Bailly was led to reprimand severely a man belonging to the humblest and poorest cla.s.s of society. Anger does not make him forget that he speaks to a citizen, to a man. "I ask pardon," says the first magistrate of the capital, addressing himself to a rag-gatherer; "I ask your pardon, if I am angry; but your conduct is so reprehensible, that I cannot speak to you otherwise."
Bailly"s friends were wont to say that he devoted too much of his patrimony to pleasure. This word was calumniously interpreted. Merard Saint Just has given the true sense of it: "Bailly"s pleasure was beneficence."
So eminent a mind could not fail to be tolerant. Such in fact Bailly constantly showed himself in politics, and what is almost equally rare, in regard to religion. In the month of June, 1791, he checked in severe terms the fury with which the mult.i.tude appeared to be excited, at the report that at the Theatines some persons had taken the Communion two or three times in one day. "The accusation is undoubtedly false," said the Mayor of Paris; "but if it were true, the public would not have a right to inquire into it. Every one should have the free choice of his religion and his creed." Nothing would have been wanting in the picture, if Bailly had taken the trouble to remark how strange it was, that these violent scruples against repeated Communions emanated from persons who probably never took the Sacrament at all.
The reports on animal magnetism, on the hospitals, on the slaughter-houses, had carried Bailly"s name into regions, whence the courtiers knew very cleverly how to discard true merit. _Madame_ then wished to attach the ill.u.s.trious academician to her person as a cabinet secretary. Bailly accepted. It was an entirely honorary t.i.tle. The secretary saw the princess only once, that was on the day of his presentation.
Were more important functions reserved for him? We must suppose so; for some influential persons offered to procure Bailly a t.i.tle of n.o.bility and a decoration. This time the philosopher flatly refused, saying, in answer to the earnest negotiators: "I thank you, but he who has the honour of belonging to the three princ.i.p.al academies of France is sufficiently decorated, sufficiently n.o.ble in the eyes of rational men; a cordon, or a t.i.tle, could add nothing to him."
The first secretary of the Academy of Sciences had, some years before, acted as Bailly did. Only he gave his refusal in such strong terms, that I could not easily believe them to have been written by the timid pen of Fontenelle, if I did not find them in a perfectly authentic doc.u.ment, in which he says: "Of all the t.i.tles in this world, I have never had any but of one sort, the t.i.tles of Academician, and they have not been profaned by an admixture of any others, more worldly and more ostentatious."
Bailly married, in November, 1787, an intimate friend of his mother"s, already a widow, only two years younger than himself. Madame Bailly, a distant relation of the author of the _Ma.r.s.eillaise_, had an attachment for her husband that bordered on adoration. She lavished on him the most tender and affectionate attention. The success that Madame Bailly might have had in the fashionable world by her beauty, her grace, by her ineffable goodness, did not tempt her. She lived in almost absolute retirement, even when the learned academician was most in society. The Mayor"s wife appeared only at one public ceremony: the day of the benediction of the colours of the sixty battalions of the National Guard by the Archbishop of Paris, she accompanied Madame de Lafayette to the Cathedral. She said: "My husband"s duty is to show himself in public wherever there is any good to be done, or sound advice to be given; mine is to remain at home." This rare retiring and respectable conduct did not disarm some hideous pamphleteers. Their impudent sarcasms were continually attacking the modest wife on her domestic hearth, and troubling her peace of mind. In their logic of the tavern they fancied that an elegant and handsome woman, who avoided society, could not fail to be ignorant and stupid. Thence arose a thousand imaginary stories, ridiculous both as to their matter and form, thrown out daily to the public, more, indeed, to offend and disgust the upright magistrate than to humble his companion.
The axe that ended our colleague"s life, with the same stroke, and almost as completely, crushed in Madame Bailly, after so many poignant agitations and unexampled misfortunes, all that was left of strength of mind and power of intellect. A strange incident also aggravated the sadness of Madame Bailly"s situation. On a day of trouble, during her husband"s lifetime, she had placed the a.s.signats resulting from the sale of their house at Chaillot, amounting to about thirty thousand francs, in the wadding of a dress. The enfeebled memory of the unfortunate widow did not recall to her the existence of this treasure, even in the time of her greatest distress. When the age of the material which had secreted them began to reveal them to daylight, they were no longer of any value.
The widow of the author of one of the best works of the age, of the learned member of our three great academies, of the first President of the National a.s.sembly, of the first Mayor of Paris, found herself thus reduced, by an unheard-of turn of fortune, to implore help from public pity. It was the geometer Cousin, member of this academy, who by his incessant solicitations got Madame Bailly"s name inserted at the Board of Charity in his arrondiss.e.m.e.nt. The support was distributed in kind.
Cousin used to receive the articles at the Hotel de Ville, where he was a Munic.i.p.al Councillor, and carried them himself to the street de la Sourdiere. It was, in short, in the street de la Sourdiere that Madame Bailly had obtained two rooms gratis, in the house of a compa.s.sionate person, whose name I very much regret not having learnt. Does it not appear to you, Gentlemen, that the academician Cousin, who crossed the whole of Paris, with the bread under his arm and the meat and the candle, intended for the unfortunate widow of an ill.u.s.trious colleague, did himself more honour than if he had come to one of the sittings bringing in his portfolio the results of some fine scientific research?
Such n.o.ble actions are certainly worth good "Papers."
Affairs proceeded thus up to the revolution of the 18th Brumaire. On the 21st, the public criers were announcing everywhere, even in the street de la Sourdiere, that General Bonaparte was Consul, and M. de Laplace Minister of the Interior. This name, so well known by the respectable widow, reached even the room that she inhabited, and caused her some emotion. That same evening, the new minister (this was a n.o.ble beginning, Gentlemen) asked for a pension of 2000 francs for Madame Bailly. The Consul granted the demand, adding to it this express condition, that the first half year should be paid in advance, and immediately. Early on the 22d, a carriage stopped in the street de la Sourdiere; Madame de Laplace descends from it, carrying in her hand a purse filled with gold. She rushed to the staircase, runs to the humble abode, that had now for several years witnessed irremediable sorrow and severe misery; Madame Bailly was at the window: "My dear friend, what are you doing there so early?" exclaimed the wife of the minister.
"Madam," replied the widow, "I heard the public crier yesterday, and I was expecting you!"
If after having, from a sense of duty, expatiated upon anarchical, odious, and sanguinary scenes, the historian of our civil discords has the good fortune to meet on his progress with an incident that gratifies the mind, raises the soul, and fills the heart with pleasing emotions, he stops there, Gentlemen, as the African traveller halts in an oasis!
HERSCHEL.
William Herschel, one of the greatest astronomers that ever lived in any age or country, was born at Hanover, on the 15th of November, 1738. The name of Herschel has become too ill.u.s.trious for people to neglect searching back, up the stream of time, to learn the social position of the families that have borne it. Yet the just curiosity of the learned world on this subject has not been entirely satisfied. We only know that Abraham Herschel, great-grandfather of the astronomer, resided at Mahren, whence he was expelled on account of his strong attachment to the Protestant faith; that Abraham"s son Isaac was a farmer in the vicinity of Leipzig; that Isaac"s eldest son, Jacob Herschel, resisted his father"s earnest desire to see him devote himself to agriculture, that he determined on being a musician, and settled at Hanover.
Jacob Herschel, father of William, the astronomer, was an eminent musician; nor was he less remarkable for the good qualities of his heart and of his mind. His very limited means did not enable him to bestow a complete education on his family, consisting of six boys and four girls.
But at least, by his care, his ten children all became excellent musicians. The eldest, Jacob, even acquired a rare degree of ability, which procured for him the appointment of Master of the Band in a Hanoverian regiment, which he accompanied to England. The third son, William, remained under his father"s roof. Without neglecting the fine arts, he took lessons in the French language, and devoted himself to the study of metaphysics, for which he retained a taste to his latest day.
In 1759, William Herschel, then about twenty-one years old, went over to England, not with his father, as has been erroneously published, but with his brother Jacob, whose connections in that country seemed likely to favour the young man"s opening prospects in life. Still, neither London nor the country towns afforded him any resource in the beginning, and the first two or three years after his expatriation were marked by some cruel privations, which, however, were n.o.bly endured. A fortunate chance finally raised the poor Hanoverian to a better position; Lord Durham engaged him as Master of the Band in an English regiment which was quartered on the borders of Scotland. From this moment the musician Herschel acquired a reputation that spread gradually, and in the year 1765 he was appointed organist at Halifax (Yorkshire). The emoluments of this situation, together with giving private lessons both in the town and the country around, procured a degree of comfort for the young William. He availed himself of it to remedy, or rather to complete, his early education. It was then that he learnt Latin and Italian, though without any other help than a grammar and a dictionary. It was then also that he taught himself something of Greek. So great was the desire for knowledge with which he was inspired while residing at Halifax, that Herschel found means to continue his hard philological exercises, and at the same time to study deeply the learned but very obscure mathematical work on the theory of music by R. Smith. This treatise, either explicitly or implicitly, supposed the reader to possess some knowledge of algebra and of geometry, which Herschel did not possess, but of which he made himself master in a very short time.
In 1766, Herschel obtained the appointment of organist to the Octagon Chapel at Bath. This was a more lucrative post than that of Halifax, but new obligations also devolved on the able pianist. He had to play incessantly either at the Oratorios, or in the rooms at the baths, at the theatre, and in the public concerts. Then, being immersed in the most fashionable circle in England, Herschel could no longer refuse the numerous pupils who wished to be instructed in his school. It is difficult to imagine how, among so many duties, so many distractions of various kinds, Herschel could continue so many studies, which already at Halifax had required in him so much resolution, so much perseverance, and a very uncommon degree of talent. We have already seen that it was by music that Herschel was led to mathematics; mathematics in their turn led him to optics, the princ.i.p.al and fertile source of his ill.u.s.trious career. The hour finally struck, when his theoretic knowledge was to guide the young musician into a laborious application of principles quite foreign to his habits; and the brilliant success of which, as well as their excessive hardihood, will excite reasonable astonishment.
A telescope, a simple telescope, only two English feet in length, falls into the hands of Herschel during his residence at Bath. This instrument, however imperfect, shows him a mult.i.tude of stars in the sky that the naked eye cannot discern; shows him also some of the known objects, but now under their true dimensions; reveals forms to him that the richest imaginations of antiquity had never suspected. Herschel is transported with enthusiasm. He will, without delay, have a similar instrument but of larger dimensions. The answer from London is delayed for some days: these few days appear as many centuries to him. When the answer arrives, the price that the optician demands proves to be much beyond the pecuniary resources of a mere organist. To any other man this would have been a clap of thunder. This unexpected difficulty on the contrary, inspired Herschel with fresh energy; he cannot buy a telescope, then he will construct one with his own hands. The musician of the Octagon Chapel rushes immediately into a mult.i.tude of experiments, on metallic alloys that reflect light with the greatest intensity, on the means of giving the parabolic figure to the mirrors, on the causes that in the operation of polishing affect the regularity of the figure, &c. So rare a degree of perseverance at last receives its reward. In 1774 Herschel has the happiness of being able to examine the heavens with a Newtonian telescope of five English feet focus, entirely made by himself. This success tempts him to undertake still more difficult enterprises. Other telescopes of seven, of eight, of ten, and even of twenty feet focal distance, crown his efforts. As if to answer in advance those critics who would have accused him of a superfluity of apparatus, of unnecessary luxury, in the large size of the new instruments, and his extreme minutiae in their execution, Nature granted to the astronomical musician, on the 13th of March 1781, the unheard-of honour of commencing his career of observation with the discovery of a new planet, situated on the confines of our solar system. Dating from that moment, Herschel"s reputation, no longer in his character of musician, but as a constructor of telescopes and as an astronomer, spread throughout the world. The King, George III., a great lover of science, and much inclined besides to protect and patronize both men and things of Hanoverian origin, had Herschel presented to him; he was charmed with the simple yet lucid and modest account that he gave of his repeated endeavours; he caught a glimpse of the glory that so penetrating an observer might reflect on his reign, ensured to him a pension of 300 guineas a year, and moreover a residence near Windsor Castle, first at Clay Hall and then at Slough. The visions of George III. were completely realized. We may confidently a.s.sert, 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.
I will avail myself of this opportunity to rectify a mistake, of which ignorance and idleness wish to make a triumphant handle, or, at all events, to wield in their cause as an irresistible justification. It has been repeated to satiety, that at the time when Herschel entered on his astronomical career he knew nothing of mathematics. But I have already said, that during his residence at Bath, the organist of the Octagon Chapel had familiarized himself with the principles of geometry and algebra; and a still more positive proof of this is, that a difficult question on the vibration of strings loaded with small weights had been proposed for discussion in 1779: Herschel undertook to solve it, and his dissertation was inserted in several scientific collections of the year 1780.
The anecdotic life of Herschel, however, is now closed. The great astronomer will not quit his observatory any more, except to go and submit the sublime results of his laborious vigils to the Royal Society of London. These results are contained in his memoirs; they const.i.tute one of the princ.i.p.al riches of the celebrated collection known under the t.i.tle of _Philosophical Transactions_.
Herschel belonged to the princ.i.p.al Academies of Europe, and about 1816 he was named Knight of the Guelphic order of Hanover. According to the English habit, from the time of that nomination the t.i.tle of Sir William took the place, in all this ill.u.s.trious astronomer"s memoirs, already honoured with so much celebrity, of the former appellation of Doctor William. Herschel had been named a Doctor (of laws) in the University of Oxford in 1786. This dignity, by special favour, was conferred on him without any of the obligatory formalities of examination, disputation, or pecuniary contribution, usual in that learned corporation.
I should wound the elevated sentiments that Herschel professed all his life, if I were not here to mention two indefatigable a.s.sistants that this fortunate astronomer found in his own family. The one was Alexander Herschel, endowed with a remarkable talent for mechanism, always at his brother"s orders, and who enabled him to realize without delay any ideas that he had conceived;[15] the other was Miss Caroline Herschel, who deserves a still more particular and detailed mention.
Miss Caroline Lucretia Herschel went to England as soon as her brother became special astronomer to the king. She received the appellation there of a.s.sistant Astronomer, with a moderate salary. From that moment she unreservedly devoted herself to the service of her brother, happy in contributing night and day to his rapidly increasing scientific reputation. Miss Caroline shared in all the night-watches of her brother, with her eye constantly on the clock, and the pencil in her hand; she made all the calculations without exception; she made three or four copies of all the observations in separate registers; coordinated, cla.s.sed, and a.n.a.lyzed them. If the scientific world saw with astonishment how Herschel"s works succeeded each other with unexampled rapidity during so many years, they were specially indebted for it to the ardour of Miss Caroline. Astronomy, moreover, has been directly enriched by several comets through this excellent and respectable lady.
After the death of her ill.u.s.trious brother, Miss Caroline retired to Hanover, to the house of Jahn Dietrich Herschel, a musician of high reputation, and the only surviving brother of the astronomer.
William Herschel died without pain on the 23d of August 1822, aged eighty-three. Good fortune and glory never altered in him the fund of infantine candour, inexhaustible benevolence, and sweetness of character, with which nature had endowed him. He preserved to the last both his brightness of mind and vigour of intellect. For some years Herschel enjoyed with delight the distinguished success of his only son,[16] Sir John Herschel. At his last hour he sunk to rest with the pleasing conviction that his beloved son, heir of a great name, would not allow it to fall into oblivion, but adorn it with fresh l.u.s.tre, and that great discoveries would honour his career also. No prediction of the ill.u.s.trious astronomer has been more completely verified.
The English journals gave an account of the means adopted by the family of William Herschel, for preserving the remains of the great telescope of thirty-nine English feet (twelve metres) constructed by that celebrated astronomer.
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 piers of masonry, in the midst of the circle, where formerly stood the mechanism requisite for manoeuvring the telescope. The first of January 1840, Sir John Herschel, his wife, their children, seven in number, and some old family servants, a.s.sembled at Slough. Exactly at noon, the party walked several times in procession round the instrument; they then entered the tube of the telescope, seated themselves on benches that had been prepared for the purpose, and sung a requiem, with English words composed by Sir John Herschel himself. After their exit, the ill.u.s.trious family ranged themselves around the great tube, the opening of which was then hermetically sealed. The day concluded with a party of intimate friends.
I know not whether those persons who will only appreciate things from the peculiar point of view from which they have been accustomed to look, may think there was something strange in several of the details of the ceremony that I have just described. I affirm at least that the whole world will applaud the pious feeling which actuated Sir John Herschel; and that all the friends of science will thank him for having consecrated the humble garden where his father achieved such immortal labours, by a monument more expressive in its simplicity than pyramids or statues.
