CARBON in astate of purity is still unknown, if, as Mr. Davy has affirmed, the diamond, which has always been re- garded as this substance in a state of great purity, contains a little oxygen’. It is a constituent of almost all vegetable and animal substances. b. METALS are simple inflammable bodies, of great specific gravity, density, and opacity; and, as the result of these | qualities, possess great brilliancy or lustre from their power of reflecting almost all the light which falls. upon their surface. Their colours are generally shades of white, gray, or yellow; their hardness is considerable, and according to its degree they are more or less elastic: one only, mercury, is in a fluid state at the ordinary heat of the air. Many of them possess considerable tenacity, and are hence malleable and ductile; but some are extremely brittle. Metals are sapid and odorous when heated or rubbed; their fracture is generally hackly; their texture fibrous or foliated; and many of them are sonorous. They are excellent conductors of ca- 8 Phil.
