2085-2115 . Two Conunon Opossums. Acute Vegetative Endocarditis. 
We wish to put on record the two following cases of acute valvular endo- 
carditis. We have paid considerable attention to this condition and these 
two bring our total of endocardi tides up to six. 
2085. Both lungs are distended with air, irregularly mottled purple and 
red, crepitate very slightly but float. Bloody fluid exudes on section. Scat- 
tered throughout the lung, particularlj^ around bronchioles and blood vessels, 
are small areas of pale purple color slightly firmer than surrounding lung. 
Whole lung exudes bloody fluid on pressure. In both lungs particularly on 
costal surface and near the h lus are small hard nodules which seem like 
cysts containing a dark fluid. On section these are found to contain small 
filarial worms containing many eggs. 
The mitral valve of the heart is the seat of friable light yellow vegetative 
growth which nearly occludes the aperture. Its right posterior portion ex- 
tends across to the posterior leaflets of the aortic valve. Subjacent muscle 
is pale and there seems to be an extension from the affected valve beneath 
both the mitral and the aortic valves. The chambers do not seem dilated, 
even the left auricle. 
Liver shows nutmeg appearance. Spleen is much enlarged, having a smooth 
tense capsule. Section surface springs out on incision and presents a mottled 
purple surface with large diffvise follicles. The kidney is dull and opaque 
with irregular obscure striae which are separated by congested lines. The 
glomeruli are visible in some places but not in others. The pyramid is con- 
gested. The urine is dark brown and contains large quantities of albumin, 
many coarse granular and cell casts, red blood cells, leucocytes and free kidney 
epithelium. 
The mucosa of the stomach is irregularly swollen, opaque, dull yellow and 
gray, and covered with a small amount of slimy white mucus. Attached to 
the mucosa especially on the greater curvature are many nematodes. Be- 
ginning at the pylorus and extending throughout the duodenum and jejunum 
the mucosa is swollen, opaque, mottled pale pink and gray, and covered with 
a little yellow mucus. The serous coat shows many small petechia and many 
small pale hemorrhagic extravasations. The ileum is much less affected, 
the mucosa being more transparent. Lymph elements not enlarged. Lymph 
glands of the neck mediastinum and bronchi are slightly enlarged, homo- 
geneous, dull red. Those of the mesentery are slightly enlarged, pale red 
and yellow, but soft and not separated into cortex and^medulla. 
2115. Except for a very small passage the mitral orifice is closed with 
yellow coagulum firmly attached to its auricular surface. The venticular 
surface is slightly roughened and a small tab of coagulum is found between 
the aortic leaflet and aortic orifice. There is no evidence of dilatation or 
hypertrophy except in the left auricle. On the surface but not in the sub- 
stance of the liver are several reddish white areas about 1 cm. across ex- 
tending slightly into the liver substance. The spleen is slightly enlarged 
and has a mottled purple section surface. The kidneys show subacute diffuse 
nephritis with a hemorrhagic infarct in the left kidney. 
The stomach presents a slightly injected serosa with a swollen injected 
opaque mucosa and contains dark mucus and nematodes. The mucosa of 
the whole intestine is swollen, opaque, irregular and covered with a slimy 
yellow gray mucus with green streaks. There are several elevations of the 
mucosa with a dark depressed spot in the center. Lymphatics seem normal. 
Dr. W. B. Cadwalader has examined the central nervous 
system of the following animals and found them negative 
of pathologic change : 2 American Wild Cats, Indian Ante-
