sionally ruminate. In proof of both these facts, a rabbit, which 
had been seven days without food, died, and the cardiac portion 
of the stomach was found to contain more than half of its 
usual quantity of contents : they were rather softer than com- 
mon, and a number, amounting to 50 or 60 of distinctly for- 
med pellets the size of shot, were collected together in the 
cardiac extremity, immediately below the oesophagus. These 
could not have been formed at the time of eating, since in 
seven days, the action of the stomach would have destroyed 
their shape. They must therefore have acquired it by the 
animal chewing the cud. 
This second class of ruminants have no cuticular lining to 
their stomachs, which may arise from their being more cautious 
feeders than the others, so that they are not liable to receive 
into the stomach any thing which can injure its internal mem- 
brane. All that portion of the stomach, which corresponds with 
the first cavity in the true ruminant, has one uniform structure, 
and is covered by a viscid mucus, but beyond this there are ori- 
fices, which I believe belong to solvent glands of a very small 
size ; and towards the pylorus, the glandular appearance is 
of a different kind ; so that in these stomachs the changes the 
food goes through correspond very closely with those it un- 
dergoes in ruminants. 
The next order of animals with respect to digestion con- 
sists of the beaver and dormouse. These, both in the shape and 
general appearance of the stomach, as well as of the teeth, 
bear a close affinity to the hare ; but they have a glandular 
structure peculiar to them, which seems to correspond with the 
solvent glands of other animals ; and as the dormouse empties
