On the microscopical structure of crystals, indicating the origin of minerals and rocks

From the Proceedings of the Geological Society. Quarterly journal of the Geological Society for November 1858, vol. XIV, pp. 453-500. "Sorby's is the first to lay the groundwork for use of inclusions as geological thermometers and barometers, and as clues to the environment in which crystals grew."--Gemology by J. Sinkankas, entry no. 6216A. "For gemologists this paper is also of great importance because it focused attention on the significance of inclusions in gem crystals, which because of their inherent features aided greatly their identification. The plates clearly depict many types of liquid-gas-solid inclusions."--Gemology by J. Sinkankas, entry no. 6216A.
