Embryo, 6 mm. long. 
Dr. Lamb, Washington. 
This specimen was removed from the uterus with a curette 
and is said to be nearly three months old. The distorted 
embryo is of the three-weeks’ stage and shows extreme 
changes in its organs and tissues. The chorion is thin and 
atrophic. There is no trace of an umbilical cord, but instead 
the embryo sits upon the amnion. The spinal cord is dilated 
and the brain is fully dissociated, filling up the stumpy head 
entirely. The blood-vessels are much dilated with blood and 
all of the tissues are infiltrated with round cells which deform 
the organs and obscure their outlines. The mandible is nec- 
rotic and the distended medulla reaches almost to the mouth. 
No. 298. 
Tubal pregnancy. 
Dr. Pearce, Albany, N. Y. 
“T am sending you by this mail a Fallopian tube removed 
at an operation on March 13. The tube shows rupture over 
an hemorrhagic swelling. The clinical diagnosis is rupture 
of ectopic pregnancy. It is from a young woman, aged 
twenty-six, married, who states that the last menstruation was 
three weeks before the operation. The surgeon is positive that 
it is a case of ectopic pregnancy. I am not so sure of the diag- 
nosis, but with the history given I thought it worth while to 
send it to you, without close examination, etc.”’ 
I found two nodules, each about 10 x 6 mm., one hemor- 
rhagic and the other with hemorrhagic walls with villus-like 
bodies upon it. This second body has a lumen—the ccelom 
(?). Neither of them contained any trace of an ovum. Then 
the ends of the rupture were cut into serial sections, and in 
one of them the remnants of the ovum were found. It is 
about 4 mm. in diameter, composed of small fibrous villi 
surrounded by an irregular syncytium, decidua and blood. 
Some of the villi are invaded by leucocytes.
