‎---- EDITION ORIGINALE ---- BON EXEMPLAIRE GRAND DE MARGES ---- "VARINGON was admired by LAGRANGE who emphasized his importance in promoting the principle of virtual velocities (as is witnessed by Johann Bernoulli's letter of 1717) and in the matter of composition of forces. 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 field of forces and acceleration, which were based on Galileo's work. As well, Varignon lays down principles of the movement and measurement of water, and for the measurements of pipes in aqueducts and fountains".
