The connectivetissue forms fibrous bands constricting the openings of the uterineglands, as well as the blood-vessels in the diseased membrane ;and yet the whole decidua is exceedingly vascular. In Virchowscase there was a syphilitic history, and, therefore, he ascribesthe disease to syphilis ; in other instances no cause whatevercould be discovered, but often this disease, as well as otheraffections of the decidual endometrium, depends upon a pre-existing chronic endometritis.

Polypoid endometritis is closely simulated by bloodextravasations between the decidua and the chorion, as shown infigure Catarrhal Endometritis.—A chronic inflammation of the de-cidual endometrium will occasionally affect chiefly the glandular 1 Midler, Bau der Molen, 1867. 2 Walther, Centralbl. f.

This oc-currence gives rise to sudden gushes of fluid from the vagina,which may reach a pint in quan
