Roberts and Trent note that "This posthumous work was edited from Varignon's manuscripts by Pujol. The study opens with a general discussion of motion, declaring Varignon's discoveries in the field of forces and acceleration, which were based on Galileo's work… Varignon lays down principles of the movement and measurement of water, with applications both to flowing and gusing water, and for measurements of pipes in aqueducts and fountains." The provenance of this book comes from the coat of arms on the cover where the Horse Guards is written in German along the lower portion of the inner perimeter of the seal. The Horse Guards of the Schwerin army was one of three units for the duchy in 1805 before the entry of French troops. This unit participated in the Russian campaign and in the Napoleonic war against France. Scarce book. (Poggendorff II 1175; Roberts & Trent, 339).
