I, 146; Roberts and Trent, Bibliotheca Mechanica, p. 9; Rouse, Historic Writings on Hydraulics, 136; DSB II, p. 335. First edition of an account of towing tank experiments on the resistance of bodies of various sizes in connection with inland navigation. "Bossut was one of a very few whom d'Alembert took as students ... in 1775 he participated with d'Alembert and Condorcet in a well-known series of experiments on fluid resistance ... Bossut is one of the important figures in the history of physics and engineering education" (DSB II, p. 335). "These towing tank experiments were preceded only by those of Benamin Franklin... In the present work, Bossut reports on the experiments on the resistance of bodies in connection with inland navigation, which were conducted in 1775 by d'Alembert, Condorcet, and himself at the request of the government. Using a towing tank constructed under Bossut's supervision, it was determined that the resistance inceases as the relative area of the canal diminishes. The text describes the preparations for the experiments and supplies numerous tables of the result." (Roberts & Trent, p. 9). Very Good.
