At a recent meeting of the Academy of Sciences, in Paris, M. Cavisart read a paper on the " Alimentation of one Stomach by theDi-gestic Apparatus of another "—that is, the improvement of the digestion of weak stomachs by the addition of gastric juice taken from the stomachs of animals. Much has been said, studied, and written on this subject; bufy as yet we have few, if any, facts tending to throw light upon it. M. Cavisart brought forward no practical proof to sustain the theory, but appeared to have no doubt in his . own mind that indigestion is caused by a deficiency of gastric juice, and that if this deficiency were supplied from the sources which he suggested, digestion would, at once become perfect again. As gastric juice'is, in its natural state, of a taste and appearance that would be repulsive to Hie patient, he proposed that it should be reduced to a powder or paste, and mingled with the aliments, and thus introduced into the stomach. He seemed to have no doubt that the gastric juice of an Animal would in all respects supply the place of that ot the human stomach.
