NATURAL HISTORY OF QUADRUPEDS-

APES.

 Black Orang. Pigmy. Jocko. 



THE terms ape, monkey, and baboon are very indiscriminately 

 applied to quadrumanous, or four-handed animals by the gene- 

 rality of writers -, but here, as in all other matters of science, it is 

 very important that some precision in nomenclature should be 

 observed. I shall therefore, as I proceed, particularize some of 

 the most obvious characters by which the apes may be readily 

 distinguished from the other two groups.
