SOME ASPECTS OF THE DEVELOPMENT OF 

 COMPARATIVE PSYCHOLOGY. 



It is probably most satisfactory in every 

 way, if an address is to be general, that it 

 shall have its foundation in the line of re- 

 search which has most engaged the author 

 for a number of years past. In harmony 

 with this pi'inciple it was open to me to 

 choose either some subject bearing on the 

 anatomy and physiology of the nervous 

 system, or one dealing with animal intel- 

 ligence. To have treated the former in 

 a way satisfactory to myself would have 

 implied considerable illustration and the 

 use of the lantern, which could likely not 

 be carried out without breaking in on au 

 evening, and that was more than I eared to 

 ask the section to do; hence the selection 

 of 'Some Aspects of the Development of 

 Animal Intelligence,' as the topic of this 

 address, the treatment of which must, in 

 the nature of the case, be incomplete. 



It is no doubt true that man is more de- 

 pendent than any other animal on his en- 

 vironment, if we restrict that term to the 

 material world about us, but the very ex- 

 pression 'Every man is the product of his 

 age' conveys the truth that the greatest 

 genius can get only so far beyond the aver- 

 age thought of his time. As Darwin long 

 ago pointed out, the most important factor 

 in man 's environment is man himself. One 

 has scarcely emerged from infancy before 

 the accumulated forces of the ages in hu- 

 man traditions and knowledge begin to 

 mold the developing human being, and de- 

 termine what he shall be. So that, be as 

 independent and original as any one may,
