120 NEW YORK ZOOLOGICAL, SOCINDY: 
CASE I. 
Barbary Ape (Imacacus innus).—The animal had been some 
time in captivity or on ship-board before being delivered to the 
Park. 
On its arrival with a consignment of other animals the veteri- 
narian at once noted the condition of paralysis, which seemed to 
be fairly typical of the picture usually presented in “cage paraly- 
sis.’ The animal was also found to be tubercular, hence was 
never placed on exhibition but was kept in the quarantine station 
up to the time of its death. 
POST-MORTEM EXAMINATION. 
Examination made on date of death. 
Body.—Markedly emaciated, tissues very anemic. Heart.— 
Collapsed, flabby; otherwise apparently normal. Lungs.—Both 
lungs filled with caseous tubercular masses varying in size from a 
pea to a walnut. There is a small area of recent hemorrhage in 
the right middle lobe. Liver.—Vessels congested, a few scattered 
tubercules are present. Kidneys.—Both are studded with tuber- 
cles and the parenchyma shows a general parenchymatous nephri- 
tis. Spleen and Lymph Nodes.—Both are much congested and 
are extensively tubercular. Stomach.—Empty except for a small 
amount of yellowish fluid, no food is present. Jntestine and Gen- 
ito-Urinary Tract.—Negative. Brain and Spinal Cord.—Gross 
examination of the spinal cord after it has been hardened, showed 
meningitis, most intense at lower levels. 
MICROSCOPIC EXAMINATION. 
Cervical Cord.—In the upper cervical levels the pia-arachnoid 
shows a moderate degree of chronic thickening of the membranes, 
and in places the connective tissue cells of its structure show evi- 
dences of recent proliferation, particularly about the vessels, which 
are quite universally injected. In the lower cervical regions the 
membrane shows in addition a very marked serous exudate, which 
in places contains a good many leucocytes, chiefly mononuclear 
cells, but in places there are a good many polynuclear ones. The 
cellular exudate is most apparent about the blood vessels, which 
are mostly congested. 
The substance of the cord shows a very general dilatation of 
the lymph channels, particularly of the perivascular spaces, and in 
some places the lacunze in which the cells are lodged are also 
dilated, this without apparent shrinkage of the ganglion cells.
