The medium of ad- hesion is a filamentous tissue, the rupture of which leaves a roughness both on the lining membrane of the heart and on the surface of the polypus. The surface also presents spots of blood penetrating more or léss deeply and sometimes ramifying in- wards, as if to form vessels for the purpose of organizing the mass—for there is no doubt that polypi do become more or less organized, and there is every reason to believe that the process is the same as in false membranes. There are other polypi which appear to be of still older formation, and which may probably be dated as far back as several months prior to the death of the patient. They are completely opake like paste or cheese, exactly resemble the oldest fibrinous layers of false. aneurisms, and adhere so firmly to the walls of the heart that they cannot be detached without scraping with the scalpel and
