human foetus found in the ovarium. 105 
whether the peritoneal foldings, within which the ovarium is 
placed, rather than the membranes of the ovarium itself, 
formed the covering of the tumour. The dissection, and the 
drawing, prove that the latter was the case. 
In order to supply as much information as possible, re- 
specting a fact so curious and important in itself, the only 
one I believe on record, which offers such complete and au- 
thentic evidence of a perfect ovario-gestation, I thought it ex- 
pedient to know the internal anatomy of the tumour, and 
readily acceded to Mr. Bauer's suggestion, of giving a second 
view of the case, which should represent as many of its im- 
portant details as could be rightly ascertained. The result 
of this ulterior investigation, for which the preparation, after 
having been drawn in its original state, as seen by yourself, 
Mr. Clift, and others, was necessarily altered and cut into, 
for better demonstration, is given in a second drawing of 
Mr. Bauer, of rhe most accurate and finished execution. 
I shall only give you an explanation of the references 
marked in that drawing, which speaks for itself.
