and tasteless, are readily partaken of by the animals. When the 

 morbid process of the disease was active, these remedies have 

 been useless. While these substances may act as a specific rem- 

 edy, they certainly have a distinctively tonic effect in the cases 

 in which we have used them. However, our experience, as yet, 

 is too limited to justify a too hopeful expectation from these 

 measures. Everything- possible should be done to improve the 

 general health; sunlight, dry and well-ventilated quarters are 

 absolutely essential. A varied, as well as a nutritious diet, is 

 very important. Care should be taken to select food containing 

 a relatively proper adjustment of both organic and inorganic food 

 elements. 



DURATION. 



The disease is nearly always continuously progressive, but we 

 have observed several cases which were subject to at least tem- 

 porary cessation, covering a period of several months. It may 

 assume an acute or a chronic form. In the former case three 

 to four months is the average, while mildly progressing forms 

 may extend over a period of several years before a fatal ter- 

 mination. 



Case i. 



Barbary Ape (Macaciis iiiiiiis). — 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 EXAMIXATIOX. 



Examination made on date of death. 



Body. — Markedly emaciated, tissues very ansemic. 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 

 tubercles are present. Kidneys. — Both are studded with tuber- 

 cles and the parenchyma shows a general parenchymatous nephri-
