and have contributed from their original material, as well as to 

 the numerous friends who at this emergency have contributed 

 money to enable us to enlarge at once, pending the substantial 

 increase in circulation which is already in progress. 



At the time the earlier numbers were issued there was 

 little of that camaraderie and acquaintance among the widely 

 scattered workers in this, as in many other lines, which now is 

 one of the pleasant and encouraging features of scientific work. 

 With a growth of this fellowship we note with gratification the 

 almost entire disappearance of the acrid or acrimonious criti- 

 cism that disfigured early scientific literature in America. It is 

 now possible to admit differences of opinion or to detect errors 

 in the work of another without establishing forthwith a breach 

 of cordial relations among the workers. c. l. herrick. 





Structure and function are correlative concepts ; neither 

 is complete without the other; as cause implies effect, so func- 

 tion implies structure. These are trite statements, yet it would 

 seem that we can not be reminded too often that the under- 

 standing of life is dependent upon our ability to correlate struc- 

 tural and functional facts. It is chiefly in the interest of such 

 correlation that The Joiunial of Comparative Neurology and Psy- 

 chology is published. True, there is no more reason for consid- 

 ing the psychic process a function of the nervous system, than 

 for calling the brain a function of consciousness ; but, this aside, 

 animal behavior and the functions of the sense organs and cen- 

 tral nervous system are dependent upon neural structures, and 

 it is these which most concern us. A survey of modern re- 

 search literature shows clearly that those investigators have 

 been eminently successful who have studied structure and func- ' 

 tion at the same time. To the physiology of the senses vastly 

 more is contributed by those who know form as well as func- 

 tion, than by those who neglect anatomical conditions ; in ani- 

 mal behavior, it is from the student who attends to anatomical 

 and histological facts that a satisfactory account of the reactions 

 of an organism is to be expected.
