The obvious interpretation of the appearances described is, 
that the glandular epithelium is breaking down, that it is lost 
altogether from the ducts, but is still present in the deep por- 
tions of the glands; in breaking down the cells separate from

cavity, there enlarge, the cavity enlarging also. Similar appear- 
ances are also found in “moulds’’ of the second month; very 
likely they have been often observed and mistaken for patholog- 
ical changes. 
The blood-vessels of course lie in the dissepiments between 
the glands. I observed nothing to correspond with the “ colos- 
sal capillaries dilated into small sinuses,” mentioned by Turner 
146, 548. Were not these supposed capillaries gland cavities, 
from which the epithelium had fallen out? Occasionally the 
sections pass through a spiral artery, Cut 209, av¢, which is cut 
again and again as it twists around in its characteristic separate 
column of connective tissue.

branes in place. — The specimen to be described was obtained 
for me through the kindness of Dr. W. W. Gannett. It is an 
apparently normal uterus, which contained a normal embryo 
weighing 1150 grammes and having an umbilical cord §8 centi- 
metres long, — probably about seven months old, or a little
