Machine pour mesurer la vitesse initiale des mobiles de différens calibres, projettés sous tous les angles, depuis zéro jusqu’à la huitième partie du cercle.
- Three folding engraved plates. viii, 59 pp. Large 4to, cont. panelled marbled calf, sides decorated with elaborate gilt tooling, flat spine richly gilt, red morocco lettering piece on spine. Paris: A. Bailleul & Magimel, 1804. First edition, in an extremely pretty contemporary binding, of a scarce book. "Description of Grobert’s machine to measure initial speed. He notes in the avant-propos that his machine operates on the same principle as that of Mathey, but that it differs in form and in the distribution of its parts. Grobert’s pamphlet describes a machine designed to measure the initial speed of projectiles launched at angles from 0 to 45 degrees, and for all the calibers standard in the French artillery. Presented to the Institut National, the review by Monge, Bossut, and Prony is appended. Prony himself was involved in Grobert’s experiments."–Roberts & Trent, Bibliotheca Mechanica, p. 150. Grobert (1757-ca. 1814), a colonel in the French army who accompanied Napoleon to Egypt, was a member of several important scientific societies and the author of other books on artillery equipment and the art of fortification. Fine and pretty copy. Stamp of "JVC" on free front endpaper. [Attributes: First Edition; Hard Cover]
