470 ANIMAL INTELLIGENCE. 



the dog-lovers, who may perhaps with justice complain 

 that I have ignored a number of published facts, stand- 

 ing on more or less good authority, and appearing more 

 wonderful than any of the facts that I have rendered. To 

 this criticism I have only to answer that it is better to err 

 on the safe side, and that if the facts which I have ren- 

 dered are sufficient to prove the existence of all the 

 psychological faculties which the dog can fairly be said to 

 possess, it is of less moment that partly doubtful cases 

 should be suppressed, where the only object of introducing 

 them would be to show that some particular faculties were 

 in some particular instances more highly developed than 

 was the case in the instances here recorded.
