    MEMBRANA DECIDUA IN TUBAL GESTATION. outer surface a flocculent exudation. The uterus is enlarged and a cribriform deciduous membrane is seen on its interior. The corpus luteum is in the ovary on the same side. It is stated in the description of this preparation that the ovum which had escaped is enclosed in the chorion, and the latter has on its outer surface a flocculent exudation.^^ 1 was permitted by Dr. Wilks, conservator of the museum, to make a minute examination of this ovum, which had escaped entire through the rent in the Fallopian tube, and I had the great satisfaction, not only to discover the vesicula umbilicalis, but to see the chorion completely surrounded by a decidua, as in the preparation of tubal gestation described in this communication. If the other preparations in the museum of Guy^s Hospital were subjected to a minute anatomical investigation, there can be no doubt that in all a decidua would be found surrounding the ovum in the Fallopian tube. Respecting the nature of the membrane or substance found coating the inner surface of the uterus in the greater number of these preparations, and which has been almost universally considered to be decidua since the time of Dr. William Hunter, although no blood-vessels in it have been discovered, I shall at present refrain from expressing any positive opinion, the great object of this communication being to demonstrate the existence of a decidua around the ovum in cases of tubal gestation.
