Abstract
The use of an unheated vitamin-free casein yielded consistent evidence in showing that the heated commercial casein as a constituent of the 240-H ration of Kline et al. ('32–'33) contains a factor or factors which accelerate the rate of growth and diminish the incidence of the pellagra-like syndrome in chicks. Concentrates prepared from milk and from rice polish contain a factor or group of factors which prevents the onset of the pellagra-like syndrome in chicks. Crystalline preparations of vitamin B and of lactoflavin do not prevent the development of the syndrome in chicks. The factor or group of factors preventing the pellagra-like syndrome in chicks may be adsorbed on fullers' earth. The data as a whole indicate that the factor or group of factors which prevents and cures the dermatitis in rats (Bender et al., '36 and Ansbacher et al., '36) is identical with that which prevents the pellagra-like syndrome in chicks.
