ON THE FATE OF THE HUMAN EMBRYO IN TUBAL PREGNANCY.

Werth this condition is usually associated with gonorrhea, and there is nothing in 

 the history of my specimens which speaks against this opinion. The inflammatory 

 process is more marked in those cases containing pathological embryos than \\hrn 

 they are normal. In practically all these cases the tube lumen is present, sometimes 

 as a large semilunar slit encircling the hemorrhagic ovum and sometimes as a simple 

 tube on one side of it. It generally remains open throughout its course, showing 

 that in them, as well as in those containing normal embryos, the implantation is 

 interstitial. In general the tube lumen is small at the site of the implantation and 

 becomes large on either side as the mass extends within the tube lumen. It is 

 naturally encircled by the folds of the wall, as is well seen, for instance, in the sketch 

 of No. 808. Rough serial sections demonstrate this point satisfactorily. 



TABLE 7. List of tubed pregnancies containing pathological embryos. 



All of the specimens containing pathological embryos, whether examined or 

 not, before being sent to the laboratory, are arranged in table 7. I have also 

 included specimens Nos. 825 and 874, which were assigned to the column containing 

 pathological ova, as well as No. 808 from the column containing normal embryos. 



The specimens are arranged according to their length, and it at once appears 

 that among those containing small embryonic remnants we have nodular and vesicu- 

 lar forms. Then we have a group of larger embryos, which are regular in form but 

 atrophic. The tissues of these are also more or less dissociated. The third group 

 consists of dead embryos which are markedly dissociated, some of which have
