ruminants yet do not ruminate, as the horse and ass, have 
only one stomach, but a portion of it is lined with cuticle, in 
which situation the food is first deposited, and by remaining 
there some time is rendered afterwards more easily digestible 
when received into the other, or digesting portion. 
In comparing the teeth of those animals that ruminate, 
with those of the horse and ass, which live on nearly the 
same kind of food, the following peculiarities are met with. 
The ruminants with horns have molares in both jaws, and 
incisores only in the lower jaw. 
The ruminants without horns have, in addition to these, 
what may be called fighting teeth, or a substitute for horns. 
These are tusks in both jaws, intermediate teeth between the 
molares and tusks, and in the upper jaw two small teeth 
anterior to the tusks ; none of which can be of any use in 
eating. 
The camelo-pardalis forms an intermediate link in these 
respects. It has short horns, and has no tusks. 
The molares in both these genera of ruminants are open 
in the structure of their crown, which is not horizontal but 
oblique, the outer edge in the upper jaw and the inner in the 
lower jaw being the most prominent, so as to adapt them to 
each other. The lower jaw has less width than the upper, so 
that the lower molares fall considerably within the upper; 
when the animal eats it can only masticate with one side of 
the mouth at a time, by bringing the lower jaw to that side, 
so as to make the teeth of both jaws oppose each other; the 
teeth of that side are applied to the food three or four times, 
and then those of the opposite side.
