Psychology has passed through great changes during 

 even the last decade. Now almost every college in 

 America of much importance has its Chair of Psy-

 physical laboratories. In America alone there are two 

 periodicals devoted to this subject, and at last peda- 

 gogical institutions are attempting to found the training 

 for teachers on the laws of the mind, i.e. on psychology. 

 In fact no recent educational movement has been more

 and keen criticism of positions assumed by physiologists 

 in regard to the central nervous system. 



The psychologists have borrowed freely from the realm 

 of mental and nervous disease, all of which marks a 

 new departure from which not only psychology, but 

 physiology and practical and scientific medicine, must 

 benefit. 



It is usually a hopeful sign when methods of exact 

 estimation begin to be applied to any science. There has 

 been much diversity of opinion as to the extent to which 

 this can be or has been successfully done in psychology. 

 In the opinion of one of the most accomplished workers 

 in this department of the science, who occupied the Pre- 

 sidental Chair at the last meeting of the American 

 Psychological Association, there can be no doubt about 

 the value of such methods and their application. He 

 says : " I venture to maintain that the introduction of 

 experiment and measurement into psychology has added,
