14 . vii . ’99. — Female brought in. 
15 . vii . ’99. — Put with male ; no record of copulation. 
17 . vii . ’99. — -Pouch large, dirty. 
20 . vii . ’99. — Pouch large, fairly clean, teats red, sebaceous 
glands just appearing. 
22 . vii . ’99 \ 
24 . vii . ’99 Pouch relaxed, but not quite clean, glands 
26 . vii . ’99 small. 
28. vii. ’99 
31 . vii . ’99. — Pouch quite relaxed, moist, glands fairly well 
marked; apparently pregnant. 
Killed, but nothing found in the uteri, which were enlarged. 
The ovaries were sectioned and show full-grown corpora lutea, 
somewhat older than those of Case 3. 
The mucosa is thickened and its surface is thrown into 
well-marked folds. The uterine epithelium is very similar to 
that of Case 3, and is for the most part in process of degenera- 
tion. In places it appears as a practically unaltered layer of 
cubical cells, but over most of its extent, it exhibits evident 
signs of degenerative change. It is very irregular both in 
contour and thickness and is invaded by leucocytes. More- 
over, cells may be seen in process of desquamation from its 
outer surface, and in places, it appears actually to have broken 
down, since extravasated blood, in which occur degenerate 
cell-products, is present in small quantities in the uterine 
cavity close to the surface of the epithelium. 
The uterine glands have been reconstituted throughout their 
extent. They are lined by a quite Ioav epithelium, and their 
lumina are occupied more or less completely by cellular 
masses (containing leucocytes), in a more or less advanced 
stage of degeneration. 
The connective tissue is very cellular and is invaded by 
large numbers of leucocytes. 
Making allowance for individual variations due to age 
or other causes, the foregoing Cases afford evidence of the 
occurrence of progressive, regressive and regenerative changes 
in the uterine mucosa, daring this period of pseudo-pregnancy.
