Left Ovary. — The main mass of the gland consists of fibrous stroma not 
unlike that of a normal ovary. It has a very rich blood-supply and contains 
a few peculiar glandular structures. Small structures, in appearance like 
Graafian follicles containing unripe ova, are found, but less numerous than 
in a normal human ovary. The ova have a mean diameter of '033 mm., 
with nuclei of diameter -013 mm. The sizes of these ova correspond closely 
to those of rabbit ova examined. 
Might Ovary. — In parts this organ shows the same structure as the left 
ovary — i. e. fibrous stroma, peculiar glandular structures, Grraafian follicles, 
and unripe ova. Other parts of the organ, however, are quite distinct and 
have the appearance of testicular substance. Here we find tubules very 
similar to seminiferous tubules with a lumen in most ; no actual sperma- 
tozoa, however, could be detected, leading to the assumption that this 
testicular tissue could not have been functional. In parts this substance 
had the tubular appearance of epididymis, showing in some sections a dis- 
tinct tubular outlet lined with columnar epithelium similar to the ductus 
deferens.
