lodged j and it was not very abfurd to conclude,, 
that Nature might have formed them for the diftindt 
repofitories of the two fexes. Accordingly this was 
fuppofed to take place in the human uterus which 
has been defcribed and delineated as if diftinguifhed 
into two chambers. Hence arofe the opinion, which 
is. received in fome places to this day, that a very 
lure prognoftic, with regard to the fex of the child, 
.may be drawn from the fide of the belly on which 
the tumour is more fenfibly felt. Diffedtions being 
now more frequent have proved, that the human 
womb generally .has only one undivided cavity; fo 
that the Joetw, let it come from which tube it may, 
will, when arrived to a certain fize, occupy it en- 
tirely. This obfervation, however, is not fufhcient 
to refute the fuppofition that each fex might have its 
peculiar ovarium ; and fome authors pretend, that 
they are able to determine how many males or fe- 
males any animal has brought forth, by examining 
the number of cicatrices on its ovaria . For, when 
females only had been produced, the right ovarium 
was found ftill full of vejicles , but the left quite 
exhaufted. That this is not always the cafe in 
brutes, appears from the obfervation of Dr. harvey, 
who frequently found male foetus' in the left cornu , 
and females in the right. In the human fubjedt, 
opportunities of afcertaining this matter muff occur 
very feldom. We have an inftance, recorded by 
cyprian, where both a boy and a girl were con- 
ceived, although the right tube was wanting. But 
the prefent cafe affords another example, which is 
decifive ; for here the impregnated uterus had not 
the fmalleft communication with the left ovarium or 
tube, and yet it contained a femal z foetus.
