 of comprehending new ideas, of acquiring and 

 memorizing novel information, and therefore of 

 improving their minds, would be to go counter to 

 all human experience. 



The extent of this capability, however, remains 

 a question, and one upon which close observation 

 of our domestic animals, our pets, and particularly 

 of those animals trained for the amusement of the 

 public, is calculated to throw much light. The 

 study of wild animals in their native haunts may 

 inform us what progress each has made in adapt-

 are capable of further or, at any rate, divergent
