Ovum, 12 mm. in diameter. 
Professor Brodel, Baltimore. 
The specimen came from a tubal pregnancy, is dumb-bell- 
shaped, and had been opened by Professor Brédel, who found 
no trace of an embryoein it. It was hardened immediately 
and later cut into serial sections. At no point in the sections 
could any trace of an embryo be found, although it is pos- 
sible, but improbable, that it was lost while the fresh specimen 
was being examined.

The ccelom contains some granular magma. The meso- 
derm of the main wall of the chorion is apparently normal, 
but that of the villi is cedematous. There are no blood-ves- 
sels present. At many points the syncytium is necrotic, fre- 
quently rising from the villi, leaving small vesicles below. 
The necrotic masses are held together by a slimy mass, within 
which there are a great many small round cells, undoubtedly 
leucocytes.

“Last period early in August; abortion, October 20, 1906.” 
The specimen is well covered with villi and filled with a 
considerable amount of reticular magma. Within there is a 
sac, the amnion, measuring 10 mm. in diameter. It con- 
tained a granular mass, which, when floated from alcohol into 
water, took on the form of an embryo of the fourth week.
