The inclusion in, or omission from, purified diets of biotin or pteroylglutamic acid had no effect on the growth rate of the cotton rat. The requirement for nicotinic acid decreased with increase in the tryptophan content of the diet. The reproductive performance on purified diets with or without biotin and pteroylglutamic acid was poor, but was improved by the addition of liver extract. P. J. Crowe.
