REPRODUCTIVE CYCLE IX DASYURUS VIVEIUUXUS. 157 
The mucosa has a maximum thickness of 'about 3‘5 mm. 
aucl presents a markedly folded surface.' The uterine 
epithelium appears as an irregular folded" layer of low 
columnar cells and shows evident signs of degenerative 
changes, e.g. irregularities in contour both of its cells and 
nuclei, occurrence of vacuoles in the cytoplasm, presence of 
degenerated nuclei and of diffused darkly staining (chroma- 
tinic ?) granules. Moreover, blood extravasations from the 
superficial capillaries would appear to have taken place 
through clefts formed by the breaking down of the epithelial 
cells. These extravasations appear to have been slight, but 
are undoubted. Besides corpuscles, there are present in 
them, cell remnants and small, darkly staining granules. In 
this female, accordingly, the uterine epithelium, unlike the 
preceding case, has not yet been reconstituted. 
The uterine glands are in essentially the same condition as 
those of Case 2. In the deep portion of the central region of 
the thickened area of the mucosa, the parts of the glands 
therein situated appear for the most part closely packed and 
hypertrophied. The gland epithelium is formed by high, 
columnar, pale-staining cells, often vacuolated, and with small 
basally situated nuclei. The gland lumina are distinct and 
in some cases contain a staining coagulnm. 
Elsewhere the glands are in process of being reconstituted. 
They are lined by a low flattened to cubical epithelium and 
their lumina are occupied either by coagulum with embedded 
cells or by cellular masses, which differ from those of Case 2 
only in that the cells are in course of degeneration. 
The connective tissue differs strikingly from that of Case 2, 
being in the form of a fine reticular tissue, oedematous and 
extremely rich in leucocytes. 
Numerous enlarged blood-vessels are present in the mucosa, 
whilst in actual contact with the under surface of the uterine 
epithelium there are numbers of fine capillaries such as occur 
normally in this position in the late pregmant uterus.
