The most obvious proof of this is the fact that cystic disease has been known to recur in the pedicle, or in some adhesion--even in cases of normal ovariotomy it is sometimes impossible, from the amount of the adhesions, to be sure that no portion of ovarian tissue has been left behind. 2. The tumour that is removed may not be an ovarian one at all. It is only quite lately that the distinction has been clearly defined between cysts of the ovary, parovarium, and broad ligament. 3.

Other hemorrhagic discharges--especially if they observe any periodicity in their appearance--are very hard to distinguish from true menstruation. Even long after the climacteric, pathological processes--such as endometritis with the formation of polypus, or commencing malignant disease, or even disease of the heart or liver--may cause periodical haemorrhages. Hegar thinks, too, that in older women there is a permanent dilatation of the blood-vessels of the pelvic organs, due to the frequent periodical congestions accompanying menstruation. Indeed, he says that such dilatation may be demonstrated post mortem. Moreover, when a large tumour is removed the blood has less room--is confined, as it were, in smaller limits.
