Page 392 - ... of judgment and of experience. Monge and Berthollet, both members of the Institute and professors in the Polytechnic School, became, with a view to this object, the principal recruiting aids to the chief of the expedition. Were our colleagues really acquainted with the object of this expedition ? I dare not reply in the affirmative; but I know at all events that they were not permitted to divulge it. We are going to a distant country; we shall embark at Toulon ; we shall be constantly with you;...
Page 371 - Laplace has considered two remarkable epochs in connection with this fact; viz: the epoch at which the major axis of the earth's orbit coincided with the line of the equinoxes, and the epoch at which it stood perpendicular to that line. By calculation, he found the former of these epochs to be referable to the year 4107, BC, and the latter to the year 1245, AD He accordingly suggested that the latter should be used as a universal epoch for the regulation of chronological occurrences.
Page 416 - The same epoch, if I were not precluded from entering into too minute details, would present to us interesting experiments. We should find that it is not true that, at all degrees of the thermometer, the loss of heat of a body is proportional to the excess of its temperature above that of the medium in which it is plunged...
Page 344 - ... first satellite twice the mean motion of the third, the sum is exactly equal to three times the mean motion of the second. * This numerical co-incidence, which is perfectly accurate, would be one of the most mysterious phenomena in the system of the universe if * This law is necessarily included in the law already enunciated by the author relative to the mean longitudes.
Page 408 - Observe them, for example, grouping together the lofty deeds of a great number of heroes, whose names they have not even deigned to preserve, and investing the single personage of Hercules with them. The lapse of ages has not rendered us wiser in this respect. In our own time the public delight in blending fable with history. In every career of life, in the pursuit of science especially, they enjoy a pleasure in creating Herculeses. According to vulgar opinion, there is no astronomical discovery...
Page 62 - ... Bourgeois Gentilhomme," which I had so often seen acted by Dugazon, — with this one difference, that this time it did not make me laugh. I was, however, ignorant of the consequences it might have brought upon me on my arrival at Algiers. After having made the profession of faith before Mahomedans — There is but one God, and Mahomet is his prophet, if I had been informed against to the...
Page 89 - ... on my hands already as much work as I could get through; that in this respect M. Biot was in the same position; and that, in short, I should vote for the nomination of M. Fourier. It was supposed, but I dare not flatter myself that it was the fact, that my declaration exercised a certain influence on the result of the ballot. The result was as follows: M. Fourier received thirty-eight votes, and M. Biot ten. In a case of this nature each man carefully conceals his vote, in order not to run the...
Page 22 - I once conceived the project of establishing a station on the high mountains which are in front of it. I went to see them. The alcaid of one of the neighbouring villages warned me of the danger to which I was about to expose myself. " These mountains," said he to me, " form the resort of a band of highway robbers.
Page 397 - Kleber has immortalized by proclaiming her beneficence, her noble character, in the bulletin of Heliopolis, and who moreover was already celebrated from one extremity of Asia to the other, in consequence of the bloody revolutions which her unparalleled beauty had excited among the Mamelukes. The incomparable victory which Kleber gained over the army of the Grand Vizier did not damp the energy of the Janissaries, who had seized upon Cairo while the war was raging at Heliopolis. They defended themselves...
Page 365 - Gentlemen, that in questions of science the authority of a thousand is not worth the humble reasoning of a single individual.
