and one in the other. The corpora lutea, in both cafes, appear- 

 ed to be formed by an effufion of blood, afterwards coagulated, 

 into a burft veficle. The fedtion which fhewed the corpus lu- 

 teum, difcovered its internal fubftance to be dark, with a bor- 

 der of a yellowiih colour, as if formed of coagulating lymph, 

 feparated from crafTamentum. 



The very early impregnation, after the abortion, in this 

 cafe, is a circumftance that feems entitled to remark. Only 

 five weeks intervened between her lafl mifcarriage and her 

 death ; and it muft be fuppofed that impregnation happened a 

 considerable time before her death, from the changes which had 

 taken place. If I might be allowed to venture a conjecture of 

 the caufe of thefe phenomena, Does it not appear that there 

 might have been fome irregular contraction of the Fallopian 

 tube, which is probably mufcular, that caufed the embryo to 

 reft where it did ? It was proved there was no permanent caufe 

 of obftruction in the tube. 



Explanation of the Plates. 



Plate II. fhews the uterus and its appendages, with the en- 

 largement in the Fallopian tube, having a burft opening 

 in its middle. The whole is drawn, as nearly as poflible, 

 of the dimenfions of the parts. By the divifion of the uterus 

 may be feen its increafed thicknefs and fize, and an attempt 

 to fliew the jelly occupying the cervix uteri. 



Plate III. exhibits two figures : the one fhews the enlargement 

 of the Fallopian tube, and the appearance 6f its contents as 

 defcribed j the other exprefTes the ovarium of the fame fide, 

 with a large corpus luteum.
