Vegetative Endocarditis. 
Two cases of this rather unusual condition were observed during the year, 
one in a common opossum and one in a Hon. They both seem to be the effect 
of an acute general infection, but that in the opossum was of a short duration, 
perhaps two or three weeks, while the lion's heart has been affected for perhaps 
two months. In both do we find the aortic valve most affected, and in both is 
there an extension of the process across the short bridge of mural endocardium 
to the aortic mitral leaflet. In the opossum there is both stenosis and incom- 
petency. In the lion stenosis is more marked and the valve is probably still 
competent, but largely because of the great size of the vegetations. In both 
animals there was a slight degree of cardiac hypertrophy particularly affecting 
the left side. The chambers did not seem dilated. In the lion there was also 
an enormous sub-capsular hemorrhage around the right kidney. This is 
probably due to rupture of an artery in the renal substance. There seems to 
have been no injury or tumor. The organ was saved for exhibition purposes; 
therefore dissection was not made. The atrium of these two infections is not 
clear. 
Report of Dr. E. A. Schumann on Specimens of the 
Female Genitalia. 
The specimens of internal female genital organs exam- 
ined, about 30, showed, with one exception, no evidence 
of disease. 
1817. Black Bear. 
The specimen consists of the entire internal genitalia. The organs are normal 
except the right uterine cornu, which is thickened, dense in consistency, cov- 
ered with old adhesions, and having the abdominal ostium of the Fallopian 
tube closed. On section the walls of the cornua are thickened, especially the 
mucosa, which is deep purple in color, presents several hemorrhagic areas, and 
is of a soft degenerated character. 
Microscopically, the cornu shows the presence of the decidual remnants of 
an infected abortion. There are found, decidual cells in various stages of dis- 
integration, placental shadows, a diffuse infiltration of leucocytes and marked 
cloudy swelling of the entire mucosa. The ovary is unchanged. 
Specimens of the Central Nervous System. 
Special Notes by Dr. J. H. W. Rhein. 
The specimens of the nervous system which appeared to 
be the seat of any pathological change have, as heretofore, 
been submitted to Dr. J. H. W. Rhein. He has submitted 
notes of his examinations for this report. These notes seem 
worthy of reporting in full because of the close similarity 
of the neuropathological diagnosis. In all there is disease 
of the vascular and perivascular cells and involvement of 
the motor cells. They are in various stages of advancement 
but as yet we cannot correlate the histological changes
