character of hands as of feet, and their anterior members as much 

 the character of feet as of hands. 



In fig. 12 is represented the species of ape called the chim- 

 panzee, using the anterior member as a prehensile organ. In 

 fig. 13 another species of quadru- 

 mana is shown, where the conforma- 

 tion of all the four feet closely 

 corresponds with that of the human 

 hand, but all the four are used for 

 support and locomotion. 



It is evident that the mode of 

 locomotion to which the mixed cha-

racter of the hand and foot found in the quadrumana is best 

 adapted, is that of climbing, to which accordingly the monkey 

 tribes are more especially addicted, often carrying their young 

 clinging round their bodies as they mount. 



In fig. 14, a monkey called the maki, a species of lemur, is 

 represented in one of its habitual attitudes, carrying its young. 



17. The double purpose of prehension and locomotion assigned 

 to the members of the quadrumana, and their habitual exercise of 

 climbing in pursuit of their food and for protection from their 

 enemies, renders the occasional aid of another organ of prehension 

 necessary ; such an organ is accordingly supplied them in the 

 tail. In fig. 15 is represented the "White-throated Monkey thus 

 exercising this prehensile action. The same action is common with 

 the species called the Coaita, or Spider-Monkey, so named from 

 the extraordinary length of its extremities, and from -its motions. 

 " The tail," says Sir Charles Bell, " answers all the purposes of a 

 hand, and the animal throws itself about from branch to branch, 

 sometimes swinging by the foot, sometimes by the fore extremity,
