The right ovary is 8 mm. in diameter, firm and healthy. The left is trans- 
formed into a unilocular smooth thin wall cyst, 2 cm. in diameter. The cyst 
is oöphoronic in development, involving all of the ovarian structure. On 
section its inner surface is smooth and ghstening, the contents a clear serum.

By Dr. J. H. Rheix. 
Portions of the lumbar and cervical enlargements and of the thoracic regions 
of the cord were stained Math haemalum and acid fuchsin and Mith thionin. 
The pia was slightly infiltrated. Tiiere was some cellular Infiltration of the 
anterior septum, and the vessels here showed an increase in the nuclei of the 
walls, and a shght perivascular infiltration. 
The pial infiltration seemed to be equally distributed in the entire circum- 
ference of the cord, although perhaps a little more marked at the periphery^ of 
the anterior and posterior septa. 
The vessels of the gray matter were congested, and the walls of the vessels 
in most part showed a proliferation of the nuclei. There were a few small 
hemorrhages into the gray matter, probably agonal. 
As compared vath the human cord and the cords of monkeys, antelopes 
and dogs, there was an unusually large number of glia nuclei, which, if foundin 
the human cord, would be looked upon as a proliferation process. In some cases 
these nuclei were heaped together in masses, and were evidently pathological. 
There was also, about the ganglion cells, some pericellular round-cell infil- 
tration, and this was more marked around a few cells which were almost en- 
tirely destroyed. The ganghon cells themselves were swollen. Some showed 
eccentric nuclei, and many of them stained poorly, while one or two showed 
distinct vacuolization. In one field a ganghon cell was partly destroyed b\' a 
recent hemorrhage. There were, however, a number of cells which appeared 
normal. 
This process seemed to be fairly distinct in the lumbar and cer\ücular en- 
largements, but was not clearly demonstrated in the sections from the dorsal 
region. 
The cellular infiltration of the horns was e\hdently not leucocytic, but pre- 
sented the appearance of a connective tissue proliferation. 
The Interpretation of these findings must be taken with some caution, as it 
was impossible to make am^ comparison with the cord of a healthy lynx; but in 
comparison with the normal human cord the findings were undoubtedly patho- 
logical, and suggestive of at least a possible relation with the paralysis. 
Although these are not the exact lesions found in poliomyelitis in the human 
animal, they are at least suggestive of the same process, since the infiltrating 
cells are of the lymphatic or connective tis.sue types. There is no acute in- 
flammatory leucocytic infiltrate. Further ob-servations will be made with the 
hope of throwing some light upon the etiology of this condition and that of 
Poliomyelitis.
