The arsenious acid and carbonate of potash are now ordered to be boiled in only half the quantity of water eventually used, in order that a glass vessel of moderate size, such for example as a Florence flask, may be used. Bismutht Trisntras.—The name now bestowed upon this preparation denotes its composition. Calew Chloridum,—called Calcis Murias, was di- rected to be prepared from the residue of the sub- limation of sesquicarbonate of ammonia ; this being an operation which but few persons carry on, the chloride is now prepared by more direct means.
