Change of Structure m the human Ovarium . y § 
In the cafe before us, the uterus was as fmall as at birth, 
indeed more fo, and the left ovarium (which was perfectly 
healthy) correfponded to the ftate of the uterus. It had not 
been at all ftimulated, nor did appear capable of being ftimu- 
lated by the application of the male femen. This feems to be 
a ftrong circumftance ; for in a cafe where there was an ovum 
formed in one of the Fallopian tubes, the uterus was enlarged to 
more than twice its unimpregnated fize ; and, upon opening into 
its cavity, the decidua was obferved to be formed as completely 
as in the impregnated uterus. This preparation is ft ill p re- 
ferved in the collection of Windmill-ftreet. Nothing can be a 
ftronger proof, that when an impregnation takes place out of the 
cavity of the uterus, the uterus ftill takes a ftiare in the aCtion, 
and undergoes fome of the changes of impregnation. In another 
preparation, which is preferved in the fame collection, where 
there was a foetus formed in the ovarium, the uterus was 
increafed to more than twice its ordinary fize, was very thick 
and fpungy, and had its blood-veffels enlarged as in an im- 
pregnated uterus. This becomes another very ftrong proof of 
the aCiion of the uterus in the formation of an extra-uterine 
foetus. In the cafe before us, however, the uterus had under- 
gone no change, and does not feem to have arrived at that 
period, when it could be capable of undergoing fuch a change. 
Befides, we are not to confider the formation of teeth in the 
ovarium to be a quicker procefs than it is commonly in the 
head of a foetus; but in the prefen t cafe the teeth having 
advanced fully as far as they are at fome months after birth, 
this procefs muft have begun at lead more than a twelvemonth 
before the death of the child. If then we confider it as an 
impregnation, fince the appearances of thechild'do not warrant 
us to believe her to have been more than twelve or thirteen years 
L 2 old.
