marked fibrous degeneration. The embryo itself is normal 
in shape, but the brain is greatly dissociated and the liver is 
cloudy and projects into the cord. 
All of the epidermis is exfoliated with great masses of 
migrating cells lying between the embryo and the envelope 
of magma.

“Beginning of last menstrual period, March 8, 1897. Abor-

The ovum appears normal with the villi distributed equally

reticulé, in which could be discerned the faint outline of a 
four-weeks embryo. A block of the chorion, including magma 
and embryo, was cut into serial sections. 
The form of the embryo, amnion and umbilical vesicle is 
normal. On one side of the embryo the epidermis is wanting 
and the amnion is filled with cells. The umbilical vesicle is
