UNRUPTURED TUBAL PREGNANCIES. 
It is of interest to consider together the ova obtained from 
tubal pregnancies, for it is through them that light may be 
thrown upon the question, if the embryo is pathological, 
whether its condition is inherited or is due to the bad environ- 
ment of the ovum. In case it is the former, the per cent of 
pathological embryos should not be larger than those obtained 
from the uterus; in case it is due to the latter, the per cent 
should be increased. 
It is stated by different writers that embryos are rarely 
found in tubal pregnancies, but that remnants of the chorion 
are often present. However, it is also stated that, in case 
the tube is found ruptured and much blood has escaped into 
the peritoneal cavity, the embryo may have been present, but 
could not be found on account of the great quantity of blood. 
On the other hand, Professor Brodel informs me that among 
eleven specimens of tubal pregnancies found recorded in his 
catalogue of human embryos nine contained normal speci- 
mens. In my own collection seven tubal pregnancies out of 
nineteen specimens contained normal embryos. It must be 
remembered that as a rule specimens were sent to us only in 
case the surgeons who removed them found normal embryos, 
which they thought we were collecting. Considering only the 
tubes that were sent to me unopened and excluding those 
which were obtained from Dr. Kelly’s gynecological labora- 
tory, I find among seven specimens two ova without embryos, 
four with pathological embryos and but one with a normal 
embryo. The other six normal embryos spoken of above 
were all recognized by the surgeons as “‘normal and valuable 
specimens” before they came into my hands. 
Following the hint obtained by considering all of the speci- 
mens which came to me unopened, I collected all of the his- 
tories of the same kind of specimens from Dr. Kelly’s 
laboratory. These cover a period of about ten years and are 
taken from the laboratory records of over 10,000 miscel- 
laneous cases. I find that altogether 128 cases of tubal preg-
