The specimen is smooth, being covered with numerous small 
hemorrhagic spots and irregular masses of small villi. Sec- 
tions show that the decidua is infiltrated with leucocytes, with 
a consequent fibrous degeneration of the villi of the chorion. 
The villi, as well as the main wall of the chorion, are being 
invaded by leucocytes and frequently by syncytial cells. 
The dissociation of the tissues of the embryo is extreme, 
the blood from the blood-vessels having passed through their 
walls to infiltrate the surrounding tissues. This is especially 
well marked in the heart and liver. The nervous system is 
pretty well broken up and the epidermis has fallen off.
