V THE MENTAL PHENOMENA OF ANIMALS 133 



genius is distinct in kind from the man of clever- 

 ness, by reason of the working within him of 

 strong innate tendencies which cultivation may 

 improve, but which it can no more create, than 

 horticulture can make thistles bear figs. The 

 analogy between a musical instrument and the 

 mind holds good here also. Art and industry may 

 get much music, of a sort, out of a penny whistle ; 

 but, when all is done, it has no chance against an 

 organ. The innate musical potentialities of the 

 two are infinitely different.
