decree of intelligence ; because, in short, it is the one most fertile in 

 resources, most susccptihle of perfection, and least tlic slave of instinct." 



This class is divided into ten orders, the first of which is named BiMANA, 

 i. e., two-handed — of wliicli man is the sole representative. Tliis order, 

 for reasons that will appear in the sequel, will be considered hereafter. 



ORDER n. QUADRUMAXA (Four-handed). 



Tliis Order is divided into two genera — the INLinkey and tlie Lemur. 

 Thi^y use their hind feet with the same facility, and in the same manner, as 

 their hands ; hence the designation of the order. They all have intestines 

 very similar to those of man ; eyes directed forward ; the mammae on the 

 Ijreast ; the brain, with three lobes on each side, tlie posterior of whi<'h 

 covers the cerebellum and the temporal fossa'' separated fnjm the orbit by 

 a bony partition. In everything else, however, they gi'adually recede frcmi 

 him, in presenting a muzzle more and more elongated ; a tail and a gait 

 more like that of (piadrupeds ; nevertheless, the freedom of their arms and 

 the complication of their hands admit of tlieir performing many of the 

 actions of man, as well as to imitate his gestures.* (Vide Cuvier, " Le 

 Ucijue AnijiKtl .")
