human foetus found in the ovarium. 107 
microscopical power of Mr. Bauer to my assistance, he has 
enabled me to give the following explanation, consistent with 
your doctrine, contained in the last volume of the Philoso- 
phical Transactions. 
The small round, white, and opaque bodies found in the 
cells of the human ovarium, as well as in that of other animals 
in a healthy state, after they have been immersed for some 
time in alcohol, consist entirely of coagulable lymph, which 
is easily reduced, in water, to a mass of globules like those 
observed in serum ; but in the present instance, the substance 
of which the coagula consisted, seemed very different, it being 
a very strong and tenacious mucus, not soluble in water, and 
which, when pressed, yielded a vast quantity of oil, without 
the slightest appearance of any globules ; a phenomenon 
supposed to be the effect of previous disease. In the right 
ovarium there was a corpus luteum perfectly well preserved, 
not far from the cells, which did not contain any such opaque 
white bodies ; while within two other cells equally near, and 
containing the coagula or white bodies above described, no 
traces of corpora lutea could be discovered. I abstain from 
all professional observations, this not being the place to enter 
into them. 
I am, dear Sir, 
yours most truly,
