-
A contrivance for extinguishing fire by pouring in streams of carbonic acid, sulphurous acid, and other gases which do not support combustion. Drops of sulphuric acid are made to fall from a bottle, when broken, upon a mixture of chlorate of potash and sugar ; and the intense combustion of the sugar fires a surrounding mixture of charcoal, nitre, and gypsum, and dense volumes of the above-mentioned gases are evolved.-Chambers's Encyclopedia.
