An Important Work in Gemology

Pesanteur Spécifique des Corps. Ouvrage utile à l'Histoire Naturelle, à la Physique, aux Arts & au Commerce.

Two engraved plates. 1 p.l., xxiv, 453, xx pp., one leaf of errata. Large 4to, cont. marbled calf, triple gilt fillet round sides, spine nicely gilt, red morocco lettering piece on spine. Paris: Imprimerie Royale, 1787.

First edition and a very fine copy of an important work in gemology. Brisson’s research on specific gravity, presented here for the first time, was accurate enough to allow gemologists the ability to distinguish between authentic and fake precious stones. Brisson (1723-1806), was “a pioneer in scientific gemology because he recognized consistent differences in value between various gemstone species and urged that these be used as a means of identification in conjunction with color and obvious external features, especially crystal shapes, hardness, and single or double refraction…Rare.”–Sinkankas, Gemology, 932.

Brisson was a close collaborator of Lavoisier and successor of Nollet to the chair of experimental physics at the Collège de Navarre. He was an important and influential disseminator of the ideas of physics through his teaching and writings.

Attractive copy.
