In ſeven minutes, a retching enſued, and I obſerved, at the ſame time, that the animal was delirious, as it ran uP and down the room, fell on the ground, and tumbled about; then it roſe again, cried out very loud, and in about half an hour after was ſeized with convulſions, and died. 1 opened the body, and found the ſtomach very much inflamed, as the inteſtines were in ſome parts, but not ſo much as the ſtomach. There was a ſmall quan- tity of coagulated blood in the ſtomach; but I could diſ- cover no orifice from which it could have iſſued; and therefore ſuppoſed it to have been ſqueczed out of the lungs, by the animal's[training while it was vomiting.
