"but regular. History shows that the power of the extremities began to fail 
about a month before death, and was absohitely lost in the fore extremities 
three days before the animal was killed. 
Notes and statement by Dr. J. H. W. Rhein on the central nervous system. 
" Examination of the central nervous system shows the presence of marked 
round cell infiltration of pia of cortex and of spinal cord, more particularly 
in the lower thoracic and lumbar regions. Ganglion cells in the lumbar region 
are markedly diseased. There are numerous old and fresh hemorrhages and 
a moderate degree of round cell infiltration in the anterior horns." 
Two young of this animal, born three months before its death, showed 
weakness and gradual increasing paralysis of their extremities beginning 
when three months old (that is at the time of the death of their mother), and 
lasting until their d^ath, one in the seventh month and the other in the eighth 
month of life. These were found not to have changes in the central nervous 
system, but there was sufficient rachitis to account for this paralysis. This 
is the only animal we have had this year in whose history or central nervous 
system any evidence of poliomyehtis existed. 
The two cases here reported are instances of aneurysms within the peri- 
cardial sac, one of which ruptured. The blood vessels did not show any other 
changes : 
1996. Great Barbet, Auricular Aneurysm. 
There is a large mass behind the heart pushing it forward. This is covered 
with a shiny gray capsule. On opening this it was found to be filled with 
organized coagulum with a cavity at the end attached to the heart. This 
mass is 1.5x1.5 centimetres and seems to originate from the auricle poster- 
iorly. The aorta and vein can be traced behind it. 
2001. Common Mynah. Aneurysm of the Aorta with Rupture. 
The anterior and lateral air sacs are filled with clotted blood and the peri- 
cardial sac is distended with the same. On dissection a thin walled aneurysmal 
sac is found on the first part of the aorta and the blood vessels come off from 
this sac. There is a dislocation of the heart downward and to the left. The 
•aneurysmal sac is chiefly posteriorly and to the left. A small rupture is found 
on the postero-lateral surface just above the origin of the left innominate 
artery. 
2020. White Whiskered Paradoxure; Verminous Aortitis, Aneurysm and 
Rupture. 
The following case is one of imusual interest and rarity. The description 
is as exact as possible, but the specimens should be seen to be properly appre- 
ciated. The worms are now being studied by Dr. Allen J. Smith. 
In the two pleural cavities there is 100 C. C. bloody fluid. On front of the 
esophagus is a large currant jelly clot. There is a large mass in the mid por- 
tion of the thoracic aorta. Beginning with the first part of the aorta, the 
wall is irregularly thickened, dull brown and pink, and there are many pe- 
techial hemorrhages and punctuate ulcerations; these are soft and covered 
with a blood stained filmy exudate. There is a dissecting aneurysm in the 
mid part of the thoracic aorta about 6 centimetres long. This has ruptured 
on its posterior inferior side. The clot has been tunneled through so that a 
perfect passage for the aortic blood is maintained. Between the dissected 
portion of the media and intima and the outer wall various grades of ulcera- 
tion have occurred, particularly on the outer wall. In these ulcerations as 
well as those mentioned above in the first part of the aorta, blood stained 
nematodes are firmly imbedded, with about 2 m. m. of their lengths free in 
the blood stained exudate described above as covering the ulcerations. The 
swellings and ulcerations are present as quoted above as far as the renal arteries. 
Below this the aorta is swollen, yellow brown and opaque.
