-arid the two, having comprehended this orifice be- 
tween them, were joined together a little below it, 
fb as to form, by their union, a feptum or mediaflinum, 
which taking the remainder of its origin from all 
that prominent ridge called the fuperior columna , 
and defending perpendicularly, was inferted into 
the inferior columna , fo as to extend from the en- 
trance of the vagina as far backward as its pofterior 
extremity, and thus to divide it into two tubes of 
nearly equal dimenfions. But each of thefe did not 
lead folely to the womb of its own fide ; for the 
right vagina became gradually wider as it ran back- 
ward, and at lafb was fo far dilated as to compre- 
hend, within its circumference, the orifices of both 
uteri ; while that on the left fide, having taken an 
oblique direftion, ended in a cul de fac, or cacum • 
Such a conformation might have rendered k totally 
ufelefs : to prevent which, Nature, fertile in expe- 
dients, feems to have had recourle to a very extra- 
ordinary contrivance. This was a ffjure in the fep- 
tum, an inch in length, and about an inch diftant 
from the womb of that fide. Although its circum- 
ference was perfedlly fmooth, we muft acknowledge 
that it might have arifen from an accidental rupture 
of the feptum ; the lips of the wound not uniting, 
and, in procefs of time, becoming callous; and 
yet, I imagine, that the parts were originally formed 
in this manner, in order to preferve a communica- 
tion between the two vagina. 
Thus it appears, that both uteri might be im- 
pregnated through either vagina , as that on the 
right fide led dire£fly to both ; and as, by means of 
the filfiire in the feptum , the femen could eafily be
