‎---- BEL EXEMPLAIRE SUR GRAND PAPIER ET GRAND DE MARGES ---- Quatrième édition PUBLIEE PAR GASTON DARBOUX CONTENANT LES NOTES DE JOSEPH BETRAND ---- "With the appearance of the Mecanique analytique, Lagrange proposed to reduce the theory of mechanics and the art of solving problems in that field to general formulas, the mere development of which would yield all the equations necessary for the solution of every problem. The Traité united and presented from a single point of view the various principles of mechanics, demonstrated their connection and mutual dependence and made it possible to judge their validity and scope. It is divided in two parts, statics and dynamics, each of which treats solid bodies and fluids separately. The methods presented require only analytic operations, subordinated to a regular and uniform development. Each of the four sections begins with a historical account which is a model of the kind".
