Beit known that I, HENRY SPENCER BLACK- MORE, a citizen of the United States, residing at 206 Sonth Ninth avenue, Mount Vernon, in the county of Westchester and State of New York, have invented certain new andnsefinl Improvements in Processes of Making Carbide; and I do hereby declare the follow ingto be a,fnll, clear, and exact description of the invention, such as .will enable others skilled in the art towhich itappertains to make andnse'the same. a I i I i The object ,of my invention i. s' to. prodnce carbids byehemical transformation;- and it s.

The process of making magnesium car' bid which consists in exposing a molten bath containing magnesium fiuoricl to the action of calcium carbid.
