Case i. 



Bdrbary 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 anaemic. 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 haemorrhage 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. Intestine 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 lacunae in which the cells are lodged are also 

 dilated, this without apparent shrinkage of the ganglion cells.
