Abstract
Amniotic fluid of the rabbit and amniotic and allantoic fluids of the cat injected into mature rabbits do not cause ovulation. Antuitrin G and S (extracts respectively of the anterior lobe of the hy pophysis of cattle and of human urine of pregnancy) are not transmitted from the maternal blood stream to either the amniotic fluid of the pregnant rabbit or the amniotic or allantoic fluids of the pregnant cat.
