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".

From the papers he left at his death, most of which are now lost, his disciples assembled several posthumous works : Nouvelle mécanique, Eclaircissements sur l'analyse des infiniment petits and Elémens de mathématiques (1731) which was based on his courses at the Collège Mazarin. His intense pedagogical activity, extending over more than thirty years, constituted his chief contribution to the progress of science and was the source of his fame. By inaugurating a chair devoted specifically to mathematics at the Collège Mazarin, he joined the handful of men who were then teaching advanced mathematics ; and it is in this context that his work was of great importance.".
