The Cete consist of the Whales, which, though 

 resembling fishes as to general form or outline, 

 are real Mammalia in disguise ; having similar 

 bones,, lungs, teats, &c. &c. Their teeth are fre- 

 quently less osseous than in other Mammalia. 

 They feed on soft marine animals and vegetables, 

 and swim chiefly by means of their pectoral or 

 breast fins, in which are inclosed the bones of the 

 fore-feet. Their tail is horizontal, and they are 

 furnished with breathing-holes on the top of the 

 head, through which they occasionally spout the 

 water. 



The teeth forming a principal mark of dis- 

 tinction in the Linnaean arrangement of Quadru- 

 peds, it is necessary to have a clear idea of the 

 position of these organs. This will readily be ob- 

 tained from an inspection of the annexed plate, 

 in which, as the principal example, are repre- 

 sented the human teeth. 



The front-teeth are termed cutting-teeth, denies 

 primores, or incisores. The single, and more 

 sharply formed teeth on each side of these are 

 called canine-teeth, denies canini, or laniarii. The 

 remaining teeth are termed grinders, or grinding- 

 teeth, denies molar es. 



The general history of Quadrupeds has been 

 so often detailed in the various works on Natural 

 History, that a fresh publication on the subject 

 must of necessity labour under peculiar disadvan- 

 tages. The valuable works of the Count de Buf-
