270 American Fisheries Society 



The latter part of the presentation of my paper seemed to me very 

 inadequate, a matter that will be adjusted by the publication of the 

 paper itself, but I want to raise one question of general bearing in 

 reference to physiological work in the study of fishes. I know that 

 this Society has long since emphasized questions in relation to fish 

 foods, environment for fishes, also the economic side of the production 

 of large quantities of fish. To me many of those problems have a pos- 

 sible solution in a better knowledge of the physiological functions of 

 fishes, as is true, of course, of that more remote complex of factors 

 which result in the infection of fishes, thus leading to abnormal func- 

 tional states. 



It is obviously as important to understand the ability of the fish to 

 utilize food as to understand the ability of the fish to catch food. I 

 do not mean, however, to discuss this point any further than merely 

 to call attention to it.
