PSYCHOLOGY.' 



American Psychological Association.— The American Psy- 

 chological Association held its annual meeting this year at the liii- 

 versity of Pennsylvania, in connection with the meetings of the scien- 

 tific societies affiliated with the American Society of Naturalist-. 

 Hitherto the Psychological Association has met independently, but the 

 feeling has been growing that the close relation between the more re-

 suitable and desirable that their representatives should be brought 

 together. The success which has attended this first step makes it prob- 

 able that the policy will be continued in future. 



No official outline of the proceedings of the Psychological Associa-

At the first session, on Friday, Dec 27th, the opening paper, on 

 " Physiology and Psychology," was read by Prof. George S. Fullerton 

 of the University of Pennsylvania. Two years ago, at the New York 

 meeting of the Association, Prof. Fullerton outlined the relation in 

 which psychology as a natural science stands to metaphysic, and con- 

 cluded that psychology should adopt, as far as possible, the methods and 

 assumptions of the other natural sciences, and should relegate the task 

 of criticising those assumptions to a distiuct science— that of metaphy- 

 sic. The paper read this year was a continuation of the same general 

 line of thought in the investigation of the relations of psychology and 

 physiology. Taking Foster's " Physiology " as a standard, we find, 

 said Prof. Fullerton, that the author i s absolutely unable to give any
