Goldberger,1 from his experimental studies on normal men and children, has obtained strong presumptive evidence that pellagra is a dietary deficiency disease. The more recent work of Jobling and Arnold2 seems to indicate that infection with an organism belonging to the Aspergillus group plays an important part in the etiology.
