ZOOLOGY. 049 



six or four incisors ; tongue mostly somewhat slit. They 

 correspond to the Whales. 



Fatn. 15. Nasal Thricozoa, Bears. 



Nose elongated into a snout, walk upon soles; all kinds 

 of teeth, of which, however, the carnivorous or tearing 

 tooth is similar to the grinders, six incisors. 



The slower gait, originating from their walking on the 

 soles of the feet, with the less pointed molars, assign to 

 these animals a less rapacious habit of living. They 

 therefore kill no large animals, and are satisfied with 

 worms and even roots, fruit, and honey. They repeat the 

 Pigs. 



Fam. 16. Nasal Thricozoa, Apes. 



The ears begin to acquire the human form, as do even 

 the teeth ; never more than four incisors, but a longer 

 canine ; hands both fore and aft. 



These animals live upon fruits and beetles, and are by 

 their scansorial feet destined to live upon trees. Their 

 varied, piping, and sonorous cry is a property of the 

 sense of hearing, and along with it the larynx also usually 

 obtains a stronger amount of development. 



3574. It seems that every family of Thricozoa contains 

 five genera, and that these accord with the organs of 

 sense. In many families this relation is at least striking, 

 e. g. 



Among the Pigs the Elephant is obviously characterized 

 by the nose, the Hippopotamus by the skin, the Pig by the 

 dental system ; and thus by the sense of taste, the Rhino- 

 ceros by large ears, the Horse by the eyes, thus

In like manner do the Ruminantia or Cattle become 

 distinctly marshalled according to the five senses. The 

 Camel recedes from the others by its simply uplying 

 hoofs, the Musk-deer by its monstrous canine ; the Goat 

 is distinguished by its fine sense of smell, and the Giraffe
