MAMMALIA 1519 



Each of these orders has the three sorts of teeth, 

 grinders, canini, and incisors, or cutting teeth. 



In the fourth order, that of the Rodentia, the toes 

 differ but little from those of the Carnivora, but there 

 are no canine teeth, and the incisors are placed in 

 front of the mouth, and adapted to a very peculiar 

 sort of manducation. 



Then come those animals whose toes are much 

 cramped and deeply sunk in large nails, which are 

 generally curved ; they have no incisors, and in some 

 the canines disappear, while others have none of any 

 description. We comprise them all under the title 

 of Edentata. 



This distribution of the unguiculated animals 

 would be perfect and form a very regular series 

 were it not that New Holland has lately furnished 

 us with a little collateral one, consisting of animals 

 with pouches, the different genera of which are 

 connected by a general similarity of organization; 

 some of them, however, in the teeth and nature of 

 their diet corresponding to the Carnivora and others 

 to the Rodentia, and a third to the Edentata. 



The hoofed animals are less numerous, and have 

 likewise fewer irregularities. 



The Ruminantia, by their cloven foot, the absence 

 of true incisors in their upper jaw, and their four 

 stomachs, form an order that is very distinct. 



The remaining hoofed animals may all be united 

 in a single order, which I shall call Pachydermata 

 or Jumenta, the elephant excepted, which might con- 

 stitute a separate one, and which is remotely con- 

 nected with that of the Rodentia.
