MAMMALIA. 
noble attitude regards Man face to face. His eyes are sprightly 
and wide opened ; his ears are well made, and of a proper length, 
without being too broad, like those of the Ox, or too long, like those 
of the Ass. His mane harmonizes gracefully with his head, and 
is a handsome appendage to the neck, conferring an air both of 
strength and spirit. His flowing and bushy tail is an ornamental 
finish to the extremity of his body. Yery different from that 
of the Stag, Elephant, &c., and from the bare appendage of the 
Ass, the Camel, the Rhinoceros, &c., the Horse’s tail is formed of 
long and thick glossy hair which seems to spring directly from the 
end of the back. He cannot elevate his tail like the Lion, but, 
although drooping, it becomes him better, and, as he can readily 
move it from side to side, it is of great use to drive away the insects 
which might annoy him ; for although his skin is very firm, 
and covered all over with thick and close hair, it is, nevertheless, 
highly sensitive.” 
It may be useful to specify the terms employed to describe 
the principal parts of the Horse. These details will not prove 
altogether superfluous, as some of the words we are about to 
explain not unfrequently occur in conversation. 
The two parts of the head of the Horse which correspond to the 
temples in a man are above the eyes. The eyes themselves have 
a loose crescentiform fold of the conjunctiva at the inner angle, 
often erroneously called membrana nictitans, but it neither performs 
its office or possesses its muscular apparatus. The orbit, which is 
formed of seven bones, four cranial and three facial, contains the 
•globe of the eye, on the inner angle of which is situated the liaw 
(a). Fig. 46 will perfectly supply the means of verifying all 
these indications. The eye-pits (b) are deep indentations which 
lie between the eye and the ear, above the eyebrows on each side. 
The face (c) is the front of the head from the eyes to the nostrils ; 
this part corresponds to the upper part of a Man’s nose. This 
name is, however, generally applied to that portion that surrounds 
the curl or centre on the forehead from whence the hair radiates. 
The neck of the Horse is designated by the word crest (d) ; it is 
comprised from one end to the other between the mane on the 
upper side and the gullet on the lower. The fore-lock (e) is the 
portion of the mane which is on the top of the head and falls over 
on the forehead between the eyes.
