Ovum and decidua, measuring 17 x 10 x 7 mm. 
Dr. Pearce, Albany, N. Y. 
Dr. Pearce writes: “I am sending you to-day a small encap- 
sulated mass, found among curettage material, which appears 
to be a young ovum. I have refrained from attempting to 
determine definitely whether or not it contains an embryo, 
for fear of injuring a specimen which might be of value to 
you. 
“The specimen was removed April 20, 1907, six weeks after 
the last menstruation. The uterus was emptied because the 
patient had eclampsia three years ago, and since then has 
had premature delivery of two dead children. The specimen 
is preserved in 10 per cent formalin.” 
The whole mass was stained in cochineal and cut into serial 
sections, but no embryo was found in it. The sections show 
it to be composed of numerous villi, decidua and inflammatory 
tissue. Most of the villi are also fibrous and degenerated, 
some few, however, contain blood-vessels filled with embryo’s 
blood. The fragmentary walls of the chorion are very fibrous 
and the growth of the syncytium is very irregular. Undoubt- 
edly the ovum “collapsed” some days before the uterus was 
scraped. The whole specimen is buried more or less in a 
slimy mass rich in leucocytes, which indicates that the uterine 
tissue was markedly inflamed.

Ovum, about 7 mm. in diameter, with the ccelom measuring 
3x2mm._ Tubal pregnancy. 
Dr. Castler, Baltimore. 
“The tube was removed April 24, 1907, from a woman 
twenty-one years old. Last period, March 5, followed by a 
brownish discharge on April 11. Diagnosis of tubal preg- 
nancy on April 23. The abdominal cavity was found well 
filled with blood and the tube was still bleeding through the 
internal ostium. The whole tube was removed and placed in 
a 10 per cent solution of formalin.”
