The common Pachydermata we have marked off into two subdivi- 
sions, in the first of which the toes are of an even number, four or 
two, and assume something of a bifurcated appearance, approaching, 
as do also in some measure their skeletons and stomachs, the forms 
proper to ruminant animals ; in the second subdivision the toes are 
of an odd number, and want this appearance. Sus, Phacoceerus, 
and Dicotyles, are merely subgenera of theLinnsean genus Sus, which 
name we have left to the first of them. 
ORDER VIII. — Ruminantia. 
This order is naturally distinguished into two families, those with- 
out and those with horns. To the former belong the camel and 
musk ; to the latter all the other genera. Horns are of three kinds, 
specimens of which may be seen in the deciduous antler of the stag, 
the permanent invested protuberances of the cameleopard, and the 
true horn or hollow corneous case of the cow, sheep, antelope, &c. 
These differences have been employed to subdivide the second family. 
Col. Hamilton Smith divides the whole order into five tribes, the 
types of which are the camel, the stag, the giraffe, the goat, and the 
ox. Eor further particulars see our fifth volume, p. 296, et seq.
