Two engraved plates. xxxiii, 305, [1] pp. 8vo, cont. tree sheep (head of spine slightly worn, one lower corner bumped), spine gilt. Paris: Méquignon-Marvis, 1819. First edition in French, translated by Jean René Riffault des Hêtres, from the greatly enlarged second edition of A Practical Essay on Chemical Re-Agents or Tests, "an interesting early work describing approximately 60 reagents and chemical techniques, illustrated by over 180 experiments. Accum briefly traces the history of wet chemical analysis, with particular reference to the contributions of Boyle, Duclos, Bergman, Scheele, Kirwan, and Westrumb."-Neville I, p. 8. Riffault (1754-1826), was general administrator of saltpeter and gunpowder manufacture in Paris and translated from English many other chemical texts. He also published several books of his own on saltpeter, dyeing, and chemistry. Some light foxing but a very good copy. ❧ Cole 8. Neville I, p. 10.
