Within the chorion there is a vesicle (amniotic) one centi- 
meter in diameter imbedded in much magma reticulé. This 
in turn is filled with granular magma, in which there is an 
embryo about 3% weeks old. The umbilical vesicle is de- 
generated and lies in the reticular magma. 
The blood-vessels and tissues of the embryo are gorged 
with blood and the outlines of the organs are obliterated. The 
brain is solid and the spinal cord is distended and dissociated. 
The eye vesicle and lens are nearly destroyed. The umbilical 
cord is very short and wide, without marked blood-vessels, 
but it is infiltrated with round cells.
