Abstract
Mammotropic preps. made from beef or sheep pituitaries were found to be antigenically indistinguishable as far as could be detd. by technics employed for active and passive anaphylaxis, Dale and Arthus reactions, precipitin and complement fixation tests. The crop stimulating effect of beef and sheep mammotropin was neutralized by injecting the pigeon with sufficiently high dosage of antimammotropin serum prepared in rabbits against beef or sheep mammotropin.
