Six folding engraved plates. xxii, 433, [1] pp. 8vo, cont. half-sheep & marbled boards, flat spine gilt. Leipzig: Baumgärtner, 1836. First edition. "Very scarce. Kurr prepared this work as both a text book and reference work to mineralogy. It begins by defining the purpose and use of the science and giving reasons why it should be studied. The first part describes Oryktognosie or the physical and chemical characters of minerals, including crystallography, fracture, cleavage, hardness, specific weight, transparency, color, etc. This is followed by a systematic mineralogy that divides the species into: combustible minerals that don't contain metals, which are then divided by organic versus inorganic origins, minerals that contain 'light' metals, including the precious stones, epidote, tourmaline, etc., and minerals that contain 'dark' metals, including rutile, tantalite, wolframite, zincite, etc. A long section describing Geognosie follows the descriptive mineralogy. An index concludes the work."­Schuh, Mineralogy & Crystallography: A Biobibliography, 1469 to 1920 (in progress), 2548. Kurr (1798-1870), was professor of mineralogy and botany at the Polytechnic School of Stuttgart. Fine copy. Not in OCLC.
