Commercium Philosophicum et Mathematicum.

23 folding engraved plates. 2 p.l., xxviii, 484 pp.; 1 p.l., 492 pp. Two vols. Large 4to, cont. vellum over boards, crowns in gilt in center of each cover, brown leather lettering piece on each spine (Vol. II’s label is a little chipped). Lausanne & Geneva: M.M. Bousquet, 1745.

First edition. “Important for containing the evidence, as embodied in the correspondence between Leibnitz and Jean Bernoulli, on the question of the rival claims to priority in the invention of the calculus, between Newton and Leibnitz. It was the only serious claim published in Leibnitz’s favor and a tardy answer to the Commercium Epistolicum, which gave the evidence in Newton’s favor.”–Babson 196.

Our copy does not contain the portrait of Leibniz (missing in a great many copies).

Fine set. Book label of Sydney Ross.
