    tinued, any floating carbonic acid was removed from the surface of the liquid by a blast of air, and a solution of baryta was then added. In the water at 150°, a very copious precipitate was formed. This was separated by filtration under a vessel kept full of hydrogen gas to prevent the absorption of atmospheric carbonic acid by the precipitant, and the weight of the carbonate deter- mined by the method of double filters. By this procedure, 14-5 cubic inches of water at 150°, gave 3 51 grs. of carbonate of baryta, which corresponds to 11-4 vol- umes of carbonic acid gas for one hundred volumes of liquid. In the water at 212°, a precipitate was also formed, but the amount although sufficient to produce a very obvious cloudiness, was too small to be readily estimated. We propose however to determine its quantity accurately hereafter. In this experiment the liquid was in active ebullition, while the stream of gas was passing, and continued to boil fora few seconds after the removal of the gas pipe. It is thus clearly proved that water is capable of absorbing carbonic acid, in sensible quantity, while it is actually boiling under ordinary pressure.
