Fig. 5. Coagulum intro-uterinum spongiosum cavum interne velatum.
A spongeous substance, irregularly globular, flattened into a sort of depression at one part, and terminated by a round teat-like extremity at the opposite parts of its circumference.
Externally this coagulum might be taken for a cast of the interior of the uterus about three weeks after conception. This resemblance is even greater when the coagulum is cut into and laid open. A cavity is then found of shape almost triangular, with an open, smooth, and rounded orifice, the whole inside being lined by a pellucid silvery-looking membrane, not unlike a serous membrane. This membrane prolongs itself through the orifice, which it lines also, and passing outwardly, goes to join and merges into the coarser external covering of the coagulum.
A section of the walls of this intro-uterine mass, exhibits a thickness of two fifths of an inch, studded with a vast number of small apertures, not unlike a honey-comb. The colour of the divided coagulum is of a bright vermilion, but the inside of the several apertures is of a much deeper tint. The lining of the cavity consists of a very fine pellucid whitish membrane, (as I before stated,) which resting on a dark red, assumes in aspect a lilac hue: while externally the mass presented a dirty brown colour at the time of its coming into my possession, immediately after its expulsion.
