Two volumes & atlas. 8vo. , lxxii, 607, [1 blank]; , 650, [errata, blank] pp. Atlas (oblong quarto, 212 x 274 mm) containing 84 engraved plates. Modern quarter calf over marbled boards, vellum corners, gilt-stamped red and green morocco spine labels (by Bernard Middleton). Bookplates of Andras Gedeon, exlib stamp on atlas title-page. Fine. FIRST EDITION WITH THE ATLAS. The most important works by the pioneer of crystallography. "In 1822 [Hauy] published Traite de cristallographie, which contained the last version of his theory and was immediately followed by the second edition of the Traite de mineralogy, limited to the portion on systematics." [DSB]. This work greatly enlarges Hauy's theories, first published in Essai d'un theorie (1784), first recognizes hemitropical crystals. In his earlier work, "Hauy extended the six primitive forms of crystals by taking the figures obtained by splitting crystals in their directions and planes of easy fracture, always constant in a crystalline substance. Thus, secondary faces were produced to those of the primitive forms and these were related in simple ratios less than 1:6. In 1800 he sought to relate crystalline form to pyro-electric properties, especially in boracites. Often known as the founder of crystallography, his law of rational indices still bears his name."
