Flint

(flint.) [ A.S.] (Min.) A semi-pellucid stone, consisting of nearly pure silex. It is a sub-species of quartz, of different shades of color. Flints occur almost always in nodules or tubercular concretions of various and very irregular forms. They are formed in regular layers in chalk strata. How they came to be so deposited is a question geologists have not yet solved. They break with an even glo y surface; are moderately transparent, very hard, and capable of a fine polish; readily strike fire with steel; and burn to whitene . They are employed in the manufacture of gla and pottery-ware. Flint, AUSTIN, an American physician and author, B. in Ma ., 1812, has produced, besides other valuable medical works, one on the Practice of Medicine, which reached its 3d edition in 1868.
