hunter: experiments with sand fly. 319 



5. Pellagra, thus far in Kansas, has appeared almost en- 

 tirely in one restricted locality. Of the nine cases recorded 

 last year five were traced back to one town. In this region 

 flies are widely distributed and unusually abundant. 



6. No direct evidence has thus far been found which would 

 in any way warrant any conclusion with reference to an 

 association of the sand fly in the determination of the etiology 

 of pellagra. 



As far as our history of this subject goes, the appearance 

 of pellagra in Kansas is of recent occurrence. Nearly all of 

 the cases are those of natives that have never been out of the 

 state. From this it would seem that the etiology of pellagra 

 exists in Kansas. 



The situation here is not complicated through long-standing 

 conditions. It is the purpose, therefore, to continue this phase 

 of the work, and with it the correlation of the clinical and 

 pathological phases l)y the medical school of the University.
