A brief histological description is given of the ovaries, uteri, and “deciduomatous tumours” of two rats in which hæmorrhage was observed towards the end of pseudopregnancy. Although preparations of gonadotropic hormone prolonged the period of pseudopregnancy, they did not increase the frequency of the occurrence of the “tumours.” The phenomena attendant upon “placental sign,” and those associated with the hæmorrhage which accompanies the tumours, have many points of resemblance in common. The possibility that the tumours exert a general and not merely a local effect, is touched upon.
