PRONY, Gaspard Clair François Marie Riche

Recherches Physico-Mathématiques sur la Théorie des Eaux courantes.

Two folding engraved plates & 7 folding printed leaves. Numerous tables in the text. xxii, 130,[1] pp. Large 4to, orig. wrappers (spine largely perished, stitching a little loose), uncut. Paris: de l'Imprimerie Impériale, 1804. First edition and a good copy in original state. "Prony's researches were undertaken while he was in Italy at the command of Napoleon to study Italian methods of water management. He presents the principles of mechanics and organizes his experiments in such a way that they require a minimal amount of calculation by the reader. His research is limited to fluids flowing sufficient distances to insure constant speed and equality between the forces of gravity and of cohesion and friction (here Prony is drawing upon Coulomb's study of 1800). Topics discussed include velocity and pressure of water, practical applications of canals and pipes, experiments on the movement of water in cylindrical pipes, and experiments in open canals."­Roberts & Trent, Bibliotheca Mechanica, pp. 269-70. Preserved in a calf-backed box. Ex Bibliotheca Mechanica. D.S.B., XI, pp. 163-66.
