degeneration. The stroma of the villi is very fibrous, being 
invaded at many points by syncytial cells and leucocytes. At 
numerous points there are large nests of leucocytes forming 
abscesses. It is a plain case of the endometritis infecting the 
chorion. 
The embryo is imbedded in a large quantity of magma 
giving every appearance of embryo No. 79 again. The or- 
gans of the embryo are dissociated and macerated and the 
tissues stain poorly, indicating that the embryo had died a 
considerable time before the abortion took place. Again the 
central nervous system is swollen and dissociated. Migrating 
cells are found in clumps or scattered in all of the tissues. In 
general, the connective tissues are more fibrous than normal, 
the true skin showing considerable hypertrophy. The epi- 
dermis is wanting.

Solid mass, 50 x 20 X 20 mm. 
Dr. Stick, Glenville, Pa. 
Last period began April 30; abortion, July 15, 1899. 
The mass is pear-shaped and proves to be a ruptured chorion 
partly inverted and imbedded in an organized clot of blood 
and fibrin. The chorion is, of course, ruptured and at the 
point of rupture there is a mass of blood, which forms the 
large end of the pear-shaped mass. There is no amnion 
within the chorion, nor could the embryo be found. A por- 
tion of mucous membrane of the uterus is attached to the 
chorion. The villi of the chorion are normal in form, but the 
mesoderm of many of them have undergone a kind of coagu- 
lation necrosis. The syncytial cells are generally normal in 
appearance. There are many leucocytes throughout the tis- 
sues, especially within the mesoderm of the inverted chorion.

Ovum, 10 x 7 x 7 mm., found within a mass of blood 
within the uterine tube. 
Dr. Boldt, New York.
