Throughout the organic reahn a correlation of structure 

 and function is demanded. It is our aim, in TJie Journal of 

 Comparative Neurology and Psychology, to bring together 

 anatomical, physiological and psychological facts in such a 

 manner that their relations may appear. Thus, it is hoped, the 

 specialists in structural work will be impressed by the import- 

 ance of the functions of the organs which they study, while at 

 the same time those whose chief concern is animal behavior 

 will see more clearly that they cannot work to advantage unless 

 they know ivJiat is functioning. If we are to understand life 

 we must consider the organism not as a structural unit, nor yet 

 as a sum of activities, but as a functioning structure.
