    pass into it, compressed by force, more Carbonic Acid than is sufficient for saturation. Keep the solution in a well-stopped vessel. Remarks.—A solution thus prepared is commonly known by the name of soda water ; it is a pleasant mode ol exhibiting the alkali, and its powers are supposed not to be diminished by the excess ofcarbonic acid with which it is combined. Tests.— SeeNotes : Sod® Carbonatis Liquor Effervescens. LIQUOR SODE CHLORINATE. Solution of Chlorinated Soda. Take of Carbonate of Soda a pound, Distilled Water forty-eight fluidounces, Chloride of Sodium four ounces, Binoxide of Manganese three ounces, Sulphuric Acid four ounces ; Dissolve the Carbonate of Soda in two pints of Water; then put the Chloride of Sodium and Binoxide of Man- ganese, rubbed to powder, into a retort; and add to them the Sulphuric Acid, previously mixed with three fluidounces of Water and cooled. Heat the [mixture] and pass the Chlorine first through five fluidounces of Water, and afterwards into the solution of Carbonate of Soda above directed. Process.— The extrication of chlorine by the action of sulphu- ric acid upon a mixture of chloride of sodium and binoxide of manganese, has been already explained. In this case it is passed through a small quantity of water, which will combine with any hydrochloric acid that might otherwise pass into the solution of carbonate of soda. The precise nature of this solution, usually called Labarraque's Soda disinfecting Liquid, has not been determined. When the quantity of chlorine gas liberated from the ingredients here di- rected is not exceeded, no carbonic acid is expelled from the carbonate of soda, and the compound form may be made to cry-
