Exfoliation of the uterine mucous membrane in cases of phosphorus-poisoning and cholera.—The mucous mem- brane of the uterus may be separated and expelled in cases of phosphorus-poisoning (Wolfs, Wegner, Schult- zen, Riess, and Vetter [Haussmann]). In cholera it has been described by Slavjansky. 7. Foreign bodies.—These need only be mentioned. They may include a large variety. Papers wrapped round suppositories may be named. 8. Products of conception.—These include :—a, de- cidua in cases of extra-uterine pregnancy; b, decidua in cases of double uterus ; c, abortions, a. With the decidua in cases of extra-uterine pregnancy we are suffi- ciently familiar. Its expulsion, indeed, is one of the signs of the condition for which we look. Its general characters are those of the ordinary decidua vera of pregnancy, including, to naked-eye examination, the presence of uterine glands ; and, to microscopical exa- mination, the presence of decidual cells. The structure and changes of this membrane under various circumstances are well worthy of a separate study, and would furnish materials for a monograph. But in the task I have set myself my concern with them is limited by the date of one month or thereabouts, for it is only when menstruation is fairly regular in rhythm that this question comes in. The thickness of decidua vera in the first month of pregnancy is about | in. (Engelmann), or nearly 10 mm. (= 1 cm.) ; and, although it is true that the whole of this is not de- tached, the expelled membrane is a thick, fleshy mass, which is not likely to be mistaken for a true dysmen-
