    rapid in vigorous, healthy women and slow in weakly women. The region of the vera is restored more rapidly than the placental area. The first step is the thickening of the mucosa to about 2 mm., owing to the contraction of the uterus, which of course reduces the superficial extent without altering the volume of the mucosa. In consequence of this change also the gland spaces become rounder and Fig. 13.—Uterus twelve hours after artificial delivery at six months pregnancy; coagl, blood clot; D, decidua; v>i, muscularis. x 22 diams. the course of the glands straighter. I will here interpolate a descrip- tion of a human uterus, twelve hours after abortion, see Minot, 98, 428. The uterus was apparently normal; it was already very much contracted; the mucosa measured about 1 mm. in thickness; the surface was ragged and more or less covered with clotted blood, pre- senting very much the appearance so superbly figured by Coste (Devel. corps organises, pi. x. Espece humaine). Vertical sections. Fig. 13, show that the surfaces of the mucosa are very un- even ; on the free surface there is a thin layer of clotted blood, coagl; the upper or compact layer of the decidua has entirely disappeared, leaving only the deep portion, D, permeated by numerous large gland spaces, between which are partitions containing the brownish and hyaline decidual cells, and a great many blood corpuscles, which lie in the tissues as well as in the blood-vessels. The presence of blood corpuscles in the tissues is probably a constant feature of the decidua post partum. The second step is the restoration of the surface by the resorption of the blood and detritus, parallel with which advances the restora- tion of the glandular epithelium. These changes occupy apparently
