Abstract
Androgenic activity of ovaries in mice is not of necessity correlated with any histological structure of the gland. Likewise no explanation is afforded by the structure of any other gland studied. It is reasoned that such function is not likely to come from the pituitary. The interval of ovarian androgenic activity is a likely genetic inherent quality of the ovary. The [male] hormone action of the ovaries in these expts. is possibly a metabolic chemism of the gland due to temp.
