2,6 MAMMIFEROUS ANIMALS. 



The latter of these kingdoms was subdivided by 

 Linnasus into six classes, viz. Mammiferous Animals, 

 which he called Mammalia, Birds, Amphibious 

 Animals, Fishes^ Insects, and Worms. 



The class of animi'S denominated Mammalia 

 comprehends all those that nourish their young by 

 means of lactiferous glands or teats, and that have, 

 flowing in their veins, a warm and red blood. It 

 includes the ivhalcs,?in order that, from external shape 

 and habits of life, has ufually been arranged among 

 the fislies. It is tiue thatthese animals inhabit ex- 

 clusively the water, an element in which none of the 

 quadrupeds can long subsist, and are furnished like 

 the fish with fins, still, however, in every essential 

 characteristic, they exhibit an alliance to the quadru- 

 peds. They have warm blood, produce their young 

 alive, and nourish them with milk furnished from 

 teats. In their internal structure they are likewise 

 in a great measure allied to the quadrupeds, having 

 similar lungs, and two auricles, and two ventricles to 

 th? heart. 



The bodies of nearly all the mammiferous animals, 

 are covered with huir, a soft and warm clothing lia- 

 ble to little injury, and bestowed in quantity propor- 

 tioned to the necessities of the animals, and the cli- 

 mates which they inhabit. In most of the aquatic 

 quadrupeds this covering, from its too free absorptioa 

 of moisture, is vvantins:. 



The head in all the higher orders of animals, is the 

 seat oi the principal organs of sense, the mouth, the 

 nose, the eyes, and the cars. It is through the mouth
