1. Hautrind . . Camel. 



2. Zungen- . . Musk-deer.

4. Ohren- . . . Giraffe. 



5. Angen- . . Ox. 



In the Bears also we are confronted by this principle 

 of classification. 



The Skin- bear is the Common Bear. 

 The Tongue-,, is the Raccoon. 

 The Nose- is the Nasua. 

 The Ear- is the Arctitis. 

 The Eye- is the Cercoleptes. 



After this principle had been so strikingly verified in 

 several families, I proceeded with confidence also to those 

 which were more difficult, and it resulted that each con-

 hitherto been only tegumental ; all the kinds of teeth 

 different, but still very similar, being of equal height 

 and nearly equal size ; nose elevated by its whole length 

 from the face, and fleshy ; ears oval, laid close against the 

 head and having regular windings or convolutions ; eyes 

 directed forwards, with perfect eyelids, and moveable in 

 all directions. 



3576. Man by the upright walk obtains his character, 

 namely, that of bodily freedom, for his hind feet take 

 the place of all the four feet of other animals, by which 

 means the hands become free and can achieve all other 

 offices, the feet alone serving to support the body.
