164 ANALYTIC SECT. XIX. 
cecci. Ist. A _ piece of roasted mutton 
slightly powdered with salt, was put into the 
rectum of a dog. It was extracted at the expi- 
ration of eleven hours, and was found changed on 
the whole of the outside, into a whitish-brown 
saponaceous paste. A small part of the centre 
retained its fibrous appearance. 
cecci. 2nd. Two pieces of roasted veal were 
introduced into the rectum of the same dog, one ~ 
of which was inelosed in a single fold of muslin. 
They were allowed to remain sixteen hours; the 
piece without the muslin was pulverulent exter- 
nally, and seemed only to require the aid of 
moisture to have the appearance of paste; its 
centre was unaltered. The veal contained in the 
muslin exhibited nearly the same appearance, but 
its pulverulence did not extend so far towards the 
centre as in the other piece. This experiment 
succeeded less perfectly than the first; a thick 
layer of feces coated the veal, and doubtless 
sheltered it from the moisture and vital action of 
the rectum. 
cccciu. We repeated the first experiment, 
using veal instead of mutton; and the result 
being the same, it is unnecessary to detail it. 
ceecry. 3rd. A dog that had fasted twelve 
hours was killed; two drachms of gastric juice 
were obtained from the stomach, and poured into 
a small oval phial, containing a cylinder of boiled
