an irregular fashion, the central nervous system and extremi- 
ties suffering most, as is the case in numerous younger 
specimens. Later the heart stopped, and then the most resis- 
tant cells of the body continued to grow for a time until 
everything came to a standstill. 
These changes are beautifully illustrated in specimen No. 
124, which is also described and well pictured in my first 
paper upon this subject. This embryo is of the nine weeks’ 
stage, with a chorion twice too large and a menstrual history 
five weeks too long. This means that after the ninth week 
of pregnancy the embryo ceased to grow, but the chorion 
continued to expand at the same rate as the normal one 
grows, until the fourteenth week, when it aborted. What is 
also noteworthy is that the amnion did not keep pace with 
the growth of the chorion, leaving between them a large exo- 
coelom. The placenta is more or less diseased, that is, infil- 
trated with leucocytes, which at points produce small ab- 
scesses. ‘The embryo itself has atrophic ears, club-hands and 
club-feet. After the embryo had been in my possession for 
seven years it was cut into sagittal sections, which, unfortu- 
nately, did not stain well. However, they show that the skin 
is more fibrous than normal, being infiltrated with round
