SPECIES AND BREEDS. 143 



in which he can exercise a certain influence ; but 

 the variations thus produced are of a peculiar 

 kind, and do not correspond to the differences 

 of the wild Species. Let us take some examples 

 to illustrate this assertion. 



Every Species of wild Bull differs from the 

 others in its size ; but all the individuals corre-

 may differ in color from every other. All the in- 

 dividuals of the same Species of wild Bull agree 

 in the proportion of their parts, in the mode of 

 growth of the hair, in its quality, whether fine or
