OF THE ADDITIONAL MEMBRANES WHICH THE OVUM DECEIVESFROM THE UTERUS. While the ovum is taking the changes consequent uponimpregnation, the womb partaking of the general sympathyVvhich prevails over the whole uterine system, suffers a changeadapting it for the reception of the ovum. The first appear-ance of action in the womb is marked by a gi-eater activity ofthe vessels, a swelling and softness of its substance. While onthe inner surface there is an exudation, which, being convertedinto a spongy membrane, is peculiarly adapted for the recep-tion and adhesion of the ragged and vascular surface of In this plan we shall be able to observe the relations andinflections of the uterine membranes or decidua, as seen anddescribed by Dr. Hunter, and of their correctness, my obser-vations in dissection leave no doubt in my mind. AA^ the v)44. Of TlIK AVCMB. Uterus in outline; B, the amnion -with the foetus; C, thechorion^ Now it is observed, upon a careful examination ofan abortion of the early months, that besides the chorion andamnion, there is a spongy membrane of two distinct laminaewhich invests the chorion. The outermost of these is foundto surround the Avhole ovum, even investing that part whichhas become the placenta by the accumulation of vessels. Thisouter membrane then mav be represented by the line DD. Itis represented as adhering to the surface of the womb, as itmust do in fact. We observe again, that it is perforatedwhere the Fallopian tube
