Fig. 4. Coagulum intro-uterinum hæmatosum laminare cavum.

There is no nucleus in this species of coagulum. In its centre, we remark an oblong cavity, which extends nearly the whole length of the mass, and remains partially open longitudinally. The walls of this cavern are not thick.

Over the latter another coat is thrown, likewise open, the margins of whose aperture do not reach those of the inner coat. Over these again arrange themselves one, two, three, and sometimes more stratifications of grumous blood, bearing a nearer resemblance to fleshy laminæ than to membranes. Their colour is of a bright vermilion, whereas that of the two innermost coats is of a dark violet, while the central cavity itself has a perfectly dark tint.

Like the coagulum incavum, the present measures three inches in length, is oblong, and rounded at both ends, one of which has an open orifice not unlike that of the unimpregnated womb in its configuration.
