Scarce. A basic introduction to the science of crystallography extracted and translated from the author's comprehensive textbook of chemistry, Cours de Chemie (2 vols., Paris, 1847-9). The text begins by defining the nomenclature of the study including edges, angles, center, and axes, next is a definition of simple and compound forms, truncations, and bevelment. The bulk of the text then describes the six divisions of the crystallographic system. Finally, the author describes imperfections in crystal formation, dimorphism, polymorphism and isomorphism.
