That from animal food was more thick and viscid than that 
from vegetable food, and its colour was more inclining to red. 
Its sp. gr. was 1-022. It showed no traces of a free acid, or 
alkali, nor did it coagulate milk even when assisted by the most 
favourable circumstances. 
On being subjected to analysis, these two specimens were 
found to consist of

These results were obtained as follows : 
Water.—The quantity of water present was ascertained by 
evaporating to dryness a known weight of each of the specimens 
upon a water-bath. 
Chymous Principle, &c.—The proportion of this was obtained 
by adding acetic acid to a known quantity of the mass, and 
boiling them together for some time. The solid result thus 
obtained was then collected and dried as before. It consisted 
partly of a precipitate composed of the digested alimentary mat- 
ter apparently combined with the gastric principle,* and partly 
of undissolved and excrementitious alimentary matter. I consi- 
dered it, therefore, as the chyme in which the albuminous 
‘nae was not yet so completely formed, or developed, as-to 
e recognized, mixed with excrementiticus matter. 
Albuminous Matter, &c.—After the above had been removed 
by filtration, prussiate of potash was added to the acetic solution, 
which, in the chyme from vegetable food, produced no precipi- 
tate, indicating the absence of albumen ; but in the chyme from 
animal food, a copious one. The albuminous matter present in 
the latter, appears to have been partly derived from the ilesh on 
which the animal had been fed. | 
Biliary Principle—Both chymes were found to contain 
this principle. It was separated by digesting alcohol on the dried 
residuum of the chyme. This took up the biliary principle, 
* The nature of the gastric fluids, and particularly of the gastric juice, or prin- 
ciple, will be more fully considered in a subsequent part of this paper.
