The mineral tallow of Kirwan, said to be found on the coast of Finland, also on the lake Baikal, in Siberia. It resembles wax, and has hence been denominated sea-wax. It is a solid substance, spec. grav. 0.77, white, brittle, stains paper like oil, melts with a moderate heat, and burns with a blue flame and much smoke; dissolves readily in oil, and imperfectly in hot alcohol. The term maltha was likewise applied by the ancients to a species of cement, of which there were two kinds, native and factitious; one of the latter consisted of pitch, wax, plaster, and grease; another (which, it is said, they used in their aqueducts) was made of lime slacked in wine, and incorporated with melted pitch and fresh figs.
