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". (Bibliotheca mecanica p. 9) -- DSB I pp. 110/117**7990/ARM1A.
