XXIII. THE MONKEYS 



The primates constitute the highest group of animals: the 

 monkeys, apes, and man. Many have a manlike appearance, 

 and a comparison of the skeleton of a man with that of the 



Fig. 174.— (a) Hand, (d) Foot, of 

 Chimpanzee. (After Voght.) 



(c) Hand, {d) Foot, 

 OF Man. 



higher forms of monkeys shows a remarkable resemblance 

 (Fig. 177). The body is carried very erect, the arms are 

 used as in human beings, and the hands (Figs. 174, 175) 



are very similar to those 

 of man. The hind foot 

 of the monkey is also a 

 hand, in which the thumb 

 is apposable to the other 

 fingers. 



Among the lower forms 

 are the beautiful little le- 

 mur of Madagascar, and 

 the aye-aye (Fig. 176),
