TUE PEDAGOGICS OF PATHOLOGYi- 



In conformity with the established pre- 

 cedent that the presiding office shall be 

 holden for some remarks in inaugurating 

 his term of service, I venture to present 

 some reflections on the pedagogics of 

 pathology. As members of this society, and 

 of the medical profession, we are all inter-

Pedagogics — the science of teaching

Modern pedagogy is of necessity a recent 

 growth, because experimental psychology 

 itself, iipon which it is based, is barely 

 forty years old. The first laboratory for 

 experimental psychology was established 

 by "Wundt in Leipsic about 1876, while in 

 this country no such laboratory existed 

 until the one opened by Dr. G. Stanley 

 Hall, at the Johns Hopkins University 

 about 1888. Previous to this time, how- 

 ever, important contributions had been 

 made to the teaching art and the ideas of 

 Pestalozzi, of Herbart, of Rousseau, and 

 others were gradually influencing our edu- 

 cational methods. The importance of labo- 

 ratory or objective methods, the individual-
