 in black vomit, immediately after it was difcharged from 

 the ftomach, and whilil it was warm, without exciting the 

 lead uneafy fenfation in the Ikin. 



[a) Odlober 4th, i 799, three cats were confined in a 

 room, and fed with beef, which had a confiderable 

 quantity of the flaky fubftance of the vomit inferted into 

 it. This manner of feeding was continued until they had 

 eaten one drachm and a half of the flaky fubftance, a nd 

 had drank feveral ounces of the black vomit. On the 5 th, 

 the excretions of the bowels were of a dark colour ; yet 

 there could not be difcovercd any difference in their

 with bread, fteeped in black vomit for twelve days. This, 

 Mr. Parker, as well as myfelf, obferved, they ate with

 health j for they continued as well after as they were be- 

 fore the experiment, and feemed to [give the preference to 

 that kind of food] to every other which was prefented to 

 them, and they appeared to thrive equally as well as if 

 they had been fed upon corn.
