186 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 ap^Dendage 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. Very diiferent 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 

 more 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 ej'es. The ej'es themselves have 

 a loose crescentiform fold of the conjunctiva at the inner angle, 

 often erroneously called memhrana nictitans, but it neither performs 

 its ofiice or possesses its muscular apjDaratus. 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 haw 

 {a). Fig. 4G will perfectlj^ supply the means of verifying all 

 these indications. The eye-pits (h) 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 ejres to the nostrils; 

 this part corresponds to the upi:)er 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-Ioek (e) is the 

 portion of the mane which is on the top of the head and falls over 

 on the forehead between the eyes.
