Fig. 19. Ovum cum placentâ, nee vasculare, nec plenè cotyledonicâ, sed filiforme. Amnion morbosum.

(Aborted at twelve or thirteen weeks after menstruation?)

Another of the manifold species of deviation from the natural process of growth and development in the human Ovum. By its size I should judge the fœtus to be about fourteen weeks old. About that period the amnion became probably affected, and the life of the child fell a sacrifice to that circumstance. That membrane is translucid and of a brownish colour, thicker than usual, and in parts nearly opaque. Next, (reckoning outwardly,) and separated from the amnion, is another membrane, resembling closely that which lines the outer-shell of a hen’s egg. No filiform vessels appear on either of its surfaces. Between these two membranes a third is distinguishable on the left of the opening made into the Ovum, and the three are very well separated from each other. The filiform vessels which connect the outer or third membrane with the thick envelopes lying over it, are well marked in the drawing. The placenta is amorphous—not local and defined, but general and mossy. The umbilical cord is covered over by its membranes, lies by the side of the fœtus, and is about twice its length, but withered down to a bare filament. Yet the proper fœtus itself is of fair growth and plump.
