Ancient Mineralogy; or, An inquiry Respecting Mineral Substances Mentioned by the Ancients

Excerpt from Ancient Mineralogy, or an Inquiry Respecting Mineral Substances Mentioned by the Ancients: With Occasional Remarks on the Uses to Which They Were Applied In accumulating the varied objects of his science, the mineralogist has explored almost every region of the globe: the recesses of every cavern, the depths of every mine, the heart of every rock into which modern enterprise has pierced. The pro fusion of minerals thus brought to light has been submitted to analysis; and their true composition, as ascertained by the result, has furnished the basis generally adopted for their scientific arrange ment. Some writers, however, have been much guided in their classification of minerals by exter nal or physical characters collectively considered; and others, again, have regarded especially that most remarkable and constant of these physical characters, their crystalline form.
