condition was not caused by any rough handling. ‘The sac 
contained some fluid in which were many flocculi, which no 
doubt are the absent portions of the embryo. Along its spine 
the embryo is whitish, but for the remainder was dark. Now 
I do not understand that micro-organisms played any role in 
this case to bring about the condition of the embryo, but it is 
only a maceration produced by the surrounding fluid medium. 
Still, I feel some doubt about my being correct, because I have 
seen sO many cases in which there was no evidence of such 
maceration. In fact, the condition of this embryo is rather 
exceptional in my observation. Apparently the soft visceral 
parts have first given way to whatever cause it was. Per- 
haps to you this is a trivial matter, but I would like to know 
what you think of it.” 
Sections of the embryo show that all of the tissues are 
normal in form and in structure, with the exception of a great 
excess of round cells within them. Especially is this true on 
the top of the head and along the back of the embryo. The 
cedematous mass on the back is as a blister with the epidermis 
lifted off. It is filled with a granular mass, within which 
there are but few cells. All of the blood-vessels of the embryo 
are distended with blood; there is also a great quantity of 
blood within the pericardial cavity and some within the ven- 
tricles of the brain. Possibly this condition accounts for the 
excess of round cells in all of the tissues, but it cannot very 
well account for the condition on top of the head and along 
the back. Here there is a most decided infiltration of cells.

The vessels going to the vertex are much enlarged. The 
scalp of the protruding vertex is very hemorrhagic, the blood 
filling the subcutaneous tissue as well as that of the skin. The 
embryonic hair follicles appear to be normal, but the epidermis 
is also infiltrated with blood cells, and is crumbling off in 
flakes.
