12 INFINITESIMAL CALCULUS judgment, but recommended Rolle to conform more strictly to the rules of the Academy, and Sauriri to forgive the proceedings of his adversary. Rolle afterwards did justice to the calculus by acknowledging his error in op posing it, and admitted that he had been urged forward by malevolent persons, one of whom was the Abb6 Gallois. Mathematicians have differed as to the best way of expounding the principles of the calculus. Newton, as has already been stated, employed the theory of motion as the means of connecting its doctrines with the principles of ordinary analysis. Leibnitz, again, with the same view, conceived quantity as passing from one degree of magni tude to another by the continual addition of infinitely small parts. The mind finds no great difficulty in dis tinctly apprehending the subject in either way. Objec tions have, however, been taken to both, and attempts made to substitute a better. Euler considered the infinitely small quantities of Leibnitz as absolutely zeros, that have to each other ratios derived from those of the vanishing quantities which they replace. D Alembert proposed to make the basis of the calculus the consideration of the ratios of the limits of quantities. This method, as was indeed stated by D Alembert, does not differ in any material respect from Newton s prime and ultimate ratios. An English mathematician, Landen, substituted for the Newtonian method of fluxions another purely algebraical. His views are contained in a work entitled The Residual Analysis, a new branch of the Algebraic Art La- (1764). Lagrange, too, in the Memoirs of the Berlin grange. Academy for 1772, proposed to base the calculus alto gether on the expansion of functions, and thus to establish it on algebraical principles merely. He subsequently developed his method in his TJieorie des Fonctions Analytiques (1797), and in his Lemons sur le Calcid des Fonctions (1806). Lagrange, however, adopted the infini tesimal method as the basis of his most important work, viz., the Mecanique Analytique. He states in his preface to its second edition (1811) that "when we have properly conceived the spirit of the infinitesimal method, and are convinced of the exactness of its results by the geometrical method of prime and ultimate ratios, or by the analytical method of derived functions, we may employ infinitely small quantities as a sure and valuable means of abridging and simplifying our demonstrations."
