A new metal discovered by the Rev. Mr. Gregor, in the beginning of the present century, in Cornwall. Klaproth subsequently found it in the red-shorl of Hungary, and gave it the name of titanium. Lampadius was the first who completely reduced it, which he effected by charcoal only. The metal was of a dark copper colour, with much brilliancy, brittle, and in small scales considerably elastic. It tarnishes in the air, and is easily oxidised by heat: it then acquires a purple tint. It detonates with nitre, and is infusible. All the mineral acids act upon it with great energy. A ccording to Vauquelin, it is volatilized by intense heat.
