cartilage, and capable of distension and evacuation at the 

 will of the animal*. It has no ligamentum teres in the hip- 

 joint f. It has a membranous canal running along the sper- 

 matic cord from the abdomen to the tunica vaginalis J, as 

 other monkeys and quadrupeds have ; but this does not exist 

 in the champanse §. The roof of the mouth is nearly black. 



I venture to assert that the differences only which have 

 been just enumerated, without any others, would be amply 

 sufficient to establish the distinction of species ; that no 

 example can be adduced of animals deviating so far from 

 the original model of their structure as to exhibit varieties 

 like those just enumerated ; and consequently, that the dif- 

 ferences in question can be accounted for only by referring 

 the animals to species originally distinct. 



There are some points, in which man has been erroneously 

 supposed to differ from animals. The approximation of the 

 two eyes is not peculiar ; they are much nearer together 

 in the simise. 



Many other mammalia, particularly among the quadru- 

 mana, have cilia in both eyelids : this is the case in the 

 elephant. 



Although the prominent nose is a striking character of the 

 human face, particularly in comparison with the monkeys, 

 whose very name (simiafrom simus) is derived from the flat- 

 ness of this part, there is a species considerably surpassing 

 man in the length of this feature ; — the long-nosed monkey, 

 S. rostrata, or nasalis ||.

 articulated sounds.

 Pennant, History of Quadrupeds., v. ii. p. 322, pi. 104 and 105, under the 

 name of proboscis monkey. Tiie nostrils of this proboscis do not terminate, 

 as in man, close to tiie upper lip ; but at the extremity of the prominence ; 

 and the structure, in other respects, diilers essentially from that of (he 

 human nose,
