3 I CLASS IV ORDER II. & III, 



ORDER 2. QUADRUMANL 



Having four hands and cuspidate teeth. 



SIMIA, (ape, monkey, ourang-outang,) front 

 teeth four in each jaw, placed near together ; ca- 

 nine teeth solitary, longer than the others, dis- 

 tant from the remaining teeth or grinders ; grind 

 ers obtuse. 



LEMUK, (macauco ape,) front teeth in the upper 

 jaw four, intermediate ones remote : in the lower 

 jaw six, longer, stretched forward, compressed, 

 parallel, approximated ; canine teeth solitary, ap- 

 proximated ; grinders several, somewhat lobed. 

 the foremost somewhat longer and sharper. 



Remarks. This order of animals approaches 

 the first order in some particulars. But they are 

 decidedly quadrupeds; as they always walk upon 

 four legs. They have four hands, though they 

 walk upon them. For the thumb is always plac- 

 ed opposite to the other fingers, as in the human 

 hand never parallel to them like the first toe of 

 a foot. 



The brain differs widely from the human brain. 

 The cerebrum is divided on each side into three 

 lobes, whereas the human brain consists of one 

 lobe only on each side. 



ORDER 3. CABNIVORI. 



Having cuspidate teeth, and toes with nails, hit 

 no thumbs : feeding more or less on animal sub- 

 stances.
