I am not so sure of the diag-nosis, but with the history given I thought it worth while tosend it to you, without close examination, etc. I found two nodules, each about 10 x 6 mm., one hemor-rhagic and the other with hemorrhagic walls with villus-likebodies upon it. This second body has a lumen—the ccelom(?). Neither of them contained any trace of an ovum. Thenthe ends of the rupture were cut into serial sections, and inone of them the remnants of the ovum were found. It isabout 4 mm. in diameter, composed of small fibrous villisurrounded by an irregular syncytium, decidua and of the villi are invaded by leucocytes. No. i.] ORIGIN OF HUMAN MONSTERS. 291.

The specimen, apparently normal, is filled with a mass ofdense magma reticule. Serial sections failed to show even aremnant of an embryo. The structure of the .chorion andvilli is normal, possibly a little cedematous. No blood-vesselsare present. No. 302. Ovum, 25 x 20 x 15 mm.; embryo, 4 mm. Professor Brodel. The ovum is apparently normal, being covered with irregu-lar villi. Sections show, however, that the villi are fibrous,with remnants of blood-vessels within them. The syncytiumis very active and is imbedded in a reticular mass of mucusrich in leucocytes and pus.
