    THE biological activity of anhydro-oxy-progesterone when given by mouth has been further tested by C. W. Emmens and A. S. Parkes, who find that it has metrotrophic, androgenic and oestrogenic properties. It causes cornification of the vaginal epithelium of the ovariectomized rat or mouse and progestational proliferation of the endometrium, to a somewhat less extent than when given by injection, but is equally effective in producing an increase in the weight of the uterus.
