1In this paper the term antineuritic vitamin signifies the substance necessary in a diet to prevent polyneuritis in birds and paralysis in rats. The term vitamin B (Goldberger's Pellagra-preventive, P-P, factor) is confined to the water-soluble vitamin needed to prevent the pellagra-like disorder in rats with lesions of the skin and alimentary tract. The term water-soluble B vitamin, or vitamins (the water-soluble B dietary factor of McCollum and his colleagues) signifies a combination of the above two vitamins, each of which is necessary to maintain growth and health.
