230 MALL. [VoLt. XIX. 
There is some granular magma within the amniotic cavity 
with several large clumps in the coelom, where the two am- 
nions meet: 
Sections of the membranes show that the chorion is de- 
nuded of most of its villi, with the exception of the point 
over the atachment of the cord of the broken embryo. The 
entire chorion is covered with its decidua, which is rich in 
blood sinuses and infiltrated with leucocytes. But few rem- 
nants of the syncytial layer of the chorion remain. 
The whole embryo is still covered by epidermis excepting 
on top of the head, at the tail end of the body, and at the 
attachment of the umbilical cord. At these points there is a 
Fic. 207a.—A whole ovum. Reduced. 
marked destruction of the tissues, which are beginning to dis- 
integrate. The top of the head is ulcerated, in front it is 
necrotic and pigmented, as is frequently the case in other 
embryos. The nervous system shows the usual changes seen . 
in strangulated embryos. The vascular system of the embryo 
is gorged with blood, but none is within the vessels of either 
the cord or the chorion. Within the body there is quite an 
extensive migration of blood cells into the tissues, obliterating 
them in part, but the process of destruction is not so far 
advanced as in No. 205. ‘The majority of the organs can be 
still outlined. We have here a rapid infiltration with migrat- 
ing cells of an embryo of forty days, with cytolysis rather 
than dissociation of the tissues.
