During his operations in the Pyrenees, in 1794, he had known my father, who was one of the administrators of the department of the Eastern Pyrenees. Later, in 1803, when the question was agitated as to the continuation of the measure of the meridian line as far as the Balearic Islands, M. Mechain went again to Perpignan, and came to pay my father a visit. As I was about setting off to undergo the examination for admission at the Polytechnic School, my father ventured to ask him whether he could not recommend me to M. Monge. "Willingly," answered he; "but, with the frankness which is my characteristic, I ought not to leave you unaware that it appears to me improbable that your son, left to himself, can have rendered himself completely master of the subjects of which the programme consists. If, however, he be admitted, let him be destined for the artillery, or for the engineers; the career of the sciences, of which you have talked to me, is really too difficult to go through, and unless he had a special calling for it, your son would only find it deceptive." Anticipating a little the order of dates, let us compare this advice with what occurred: I went to Toulouse, underwent the examination, and was admitted; one year and a half afterwards I filled the situation of secretary at the Observatory, which had become vacant by the resignation of M. Mechain's son; one year and a half later, that is to say, four years after the Perpignan "horoscope," associated with M. Biot, I filled the place, in Spain, of the celebrated academician who had died there, a victim to his labours. [3] This appears to be an oversight, as in a preceding page M. Arago described the fortunate release of Captain Krog from this captivity. [4] On my return to Paris I hastened to the Jardin des Plantes to pay a visit to the lion, but he received me with a very unamiable gnashing of the teeth. Think then of the marvellous history of the Florentine lion, the subject of so many engravings, which is offered on the stall of every printseller to the eyes of the moved and astonished passers-by.

BIOGRAPHY READ AT THE PUBLIC SITTING OF THE ACADEMY OF SCIENCES, THE 26TH OF FEBRUARY, 1844. INTRODUCTION. Gentlemen,--The learned man, illustrious in so many ways, whose life I am going to relate, was taken from France half a century ago. I hasten to make this remark, so as thoroughly to show that I have selected this subject without being deterred by complaints which I look upon as unjust and inapplicable. The glory of the members of the early Academy of Sciences is an inheritance for the present Academy. We must cherish it as we would the glory of later days; we must hallow it with the same respect, we must devote to it the same worship: the word _prescription_ would here be synonymous with ingratitude.
