Paris: Duprat, 1802.
A fine copy of this influential text, which according to Babbage was "so perfect that any comment was unnecassary". "In discussing with a friend the formation of a section of the British and Foreign Bible Society, a society which had the distribution of Bibles as its mission, Charles Babbage facetiously suggested that they form a society to distribute Silvestre Lacroix's Traité Élémentaire de Calcul Différential et de Calcul Intégral, a work in the French analytic style." (Parshall & Rowe: Emergence of the American Mathematical Research, p.7). The result became the Cambridge Analytical Society, and in 1816 the members Babbage, Peacock and Herschel published an English translation of Lacroix's work, "thereby providing the first convinient English account of the continential version of the calculus." (Craik: Cambridge Reform and British Mathematics, p.62). Scarce in such good condition.
Original plain wrappers, uncut (much of spine worn away). A fine unsophisticated copy. Preserved in a clamshell box. XLIV, 574, (2) pp. and 5 engraved folding plates.
