M. Monge took the trouble to come to me one day, at the Observatory, to ask me to succeed him. I declined this honour, because of a proposed journey which I was going to make into Central Asia with M. de Humboldt. "You will certainly not set off for some months to come," said the illustrious geometer; "you could, therefore, take my place temporarily." "Your proposal," I replied, "flatters me infinitely; but I do not know whether I ought to accept it. I have never read your great work on partial differential equations; I do not, therefore, feel certain that I should be competent to give lessons to the pupils of the Polytechnic School on such a difficult theory." "Try," said he, "and you will find that that theory is clearer than it is generally supposed to be." Accordingly, I did try; and M. Monge's opinion appeared to me to be well founded.
The public could not comprehend, at that time, how it was that the benevolent M. Monge obstinately refused to confide the delivery of his course to M. Binet, (a private teacher under him,) whose zeal was well known. It is this motive which I am going to reveal.
There was then in the "Bois de Boulogne" a residence named the Grey House, where there assembled round M. Coessin, the high-priest of a new religion, a number of adepts, such as Lesueur, the musician, Colin, private teacher of chemistry at the school, M. Binet, &c. A report from the prefect of police had signified to the Emperor that the frequenters of the Grey House were connected with the Society of Jesuits. The Emperor was uneasy and irritated at this. "Well," said he to M. Monge, "there are your dear pupils become disciples of Loyola!" And on Monge's denial, "You deny it," answered the Emperor; "well, then, know that the private teacher of your course is in that clique." Every one can understand that after such a remark, Monge could not consent to being succeeded by M. Binet.
Having entered the academy, young, ardent, and impassioned, I took much greater part in the nominations than may have been suitable for my position and my time of life. Arrived at an epoch of life whence I examine retrospectively all my actions with calmness and impartiality, I can render this amount of justice to myself, that, excepting in three or four instances, my vote and interest were always in favour of the most deserving candidate, and more than once I succeeded in preventing the Academy from making a deplorable choice. Who could blame me for having maintained with energy the election of Malus, considering that his competitor, M. Girard, unknown as a physicist, obtained twenty-two votes out of fifty-three, and that an addition of five votes would have given him the victory over the savant who had just discovered the phenomenon of polarization by reflection, over the savant whom Europe would have named by acclamation? The same remarks are applicable to the nomination of Poisson, who would have failed against this same M. Girard if four votes had been otherwise given. Does not this suffice to justify the unusual ardour of my conduct? Although in a third trial the majority of the Academy was decided in favour of the same engineer, I cannot regret that I supported up to the last moment with conviction and warmth the election of his competitor, M. Dulong.
I do not suppose that, in the scientific world, any one will he disposed to blame me for having preferred M. Liouville to M. de Pontécoulant.
Sometimes it happened that the Government wished to influence the choice of the Academy; with a strong sense of my rights I invariably resisted all dictation. Once this resistance acted unfortunately on one of my friends—the venerable Legendre; as to myself, I had prepared myself beforehand for all the persecutions of which I could be made the object. Having received from the Minister of the Interior an invitation to vote for M. Binet against M. Navier on the occurrence of a vacant place in the section of mechanics, Legendre nobly answered that he would vote according to his soul and his conscience. He was immediately deprived of a pension which his great age and his long services rendered due to him. The protégé of the authorities failed; and, at the time, this result was attributed to the activity with which I enlightened the members of the Academy as to the impropriety of the Minister's proceedings.
On another occasion the King wished the Academy to name Dupuytren, the eminent surgeon, but whose character at the time lay under grave imputations. Dupuytren was nominated, but several blanks protested against the interference of the authorities in academic elections.
I said above that I had saved the Academy from some deplorable choices; I will only cite a single instance, on which occasion I had the sorrow of finding myself in opposition to M. de Laplace. The illustrious geometer wished a vacant place in the astronomical section to be granted to M. Nicollet,—a man without talent, and, moreover, suspected of misdeeds which reflected on his honour in the most serious degree. At the close of a contest, which I maintained undisguisedly, notwithstanding the danger which might follow from thus braving the powerful protectors of M. Nicollet, the Academy proceeded to the ballot; the respected M. Damoiseau, whose election I had supported, obtained forty-five votes out of forty-eight. Thus M. Nicollet had collected but three.
"I see," said M. de Laplace to me, "that it is useless to struggle against young people; I acknowledge that the man who is called the great elector of the Academy is more powerful than I am."
"No," replied I; "M. Arago can only succeed in counterbalancing the opinion justly preponderating for M. de Laplace, when the right is found to be without possible contradiction on his side."
