EXT:RA. UTERINE FOETUS. 191 



cavity of the uterus ; fo that there was no permanent obftrudtion 

 to the paflage of the embryo into the uterus. 



Having carefully laid open the pouch, it appeared full of a 

 firm coagulum. Upon breaking through this, at the depth oi 

 about a quarter of an inch, there appeared a membi-anous cir- 

 cle, of a lightifli colour, about the fize of a fcarlet bean, and 

 within this another fimilar membrane prefented itfelf, perfecfl- 

 ly diftindl from the former ; probably thefe membranes repre- 

 fented the chorion and amnion. Within the latter mem- 

 brane, nothing could be difcovered but coagulum. There was 

 no appearance of foetus ; but it mufl be remembered, that only 

 five weeks had elapfed fince the lafc abortion. 



The uterus was much thickened, being nearly twice its bulk 

 in an vmimpregnated ftate ; and, notwithftanding the hxmor- 

 rhage which had occurred, its veiTels appeared confiderably en- 

 larged. The cervix uteri was entii"ely filled with a jelly, and 

 the whole furface of the cavity of the uterus was lined with a 

 foftifh glutinous fubftance, which feemed organized, and was 

 much redder than the reft of the uterus. Changes had been 

 produced in the uterus fimilar to what are feen in ordinary 

 geftation ; its parietes were thickened ; its cavity enlarged ; 

 its cervix fliut up with a jelly ; and the glutinous efFufion juil: 

 defcribed might not perhaps improperly be confidered as a 

 membrana decidua in its early ftate of formation. 



The ovaria were much veficulated, particularly the left; in 

 which there was a corpus luteum of confiderable Gze : in the 

 right ovarium there was no corpus luteum. The veficles in thefe 

 ovaria were large and much diftended. Their appearance was 

 exadlly fimilar to that of the ovaria of a young woman I fome 

 time ago examined, who had died from an accident, after ha- 

 ving been married but a few days, in whofe uterus there were 

 evident marks of impregnation, and in both ovaria, corpora 

 lutea, two or three, I am not certain which, in one ovarium,
