Thus Mr. Jacob Per- kins obtained steam from a very strong boiler, so hot as to fire tow and other combustible bo- dies, and the pipes conveying hot water under a great pres- sure, according to his system, have been known to fire build- ings. (See warming. } The wa- ter and the steam from it, under pressure, have always the same temperature. An empty vessel, or one filled only with steam, is soon destroyed by heat, but as long as water remains in the vessel, heat cannot accumulate to an injurious extent.
