Uralite is the invention of a Russian Colonel of artillery, and the manufacturing rights in this country have been secured by the British Uralite Company, who have erected extensive factory at near Rochester, Kent. is a substance composed of asbestos fibre cemented with glue, and is, it is claimed, the best fire-resisting agent known science. The.test conducted yesterday proved to the satisfaction of all who witnessed it, that Uralite is all that is claimed to be. A partition composed and wood, and a deed box made the same materials, and tilled with wax, books, papers, etc., were surrounded fierce fire, which was allowed burn for nearly an hour, the temperature attained being two thousand odd degrees fahr. After the names were extinguished, the partition was stripped, when it was found that the fire had not penetrated beyond the first layer of Uralite and wood underneath. An examination of the deed box revealed similar result.'
