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 Linnasan 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, dentes canini, or laniarii. The 
remaining teeth are termed grinders, or grinding^ 
teeth, dentes 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-
