Deer House during the past year, and is now in fine condition. 

 The same is true of a number of other animals. 



Pnemnonia. — Fewer cases of pneumonia vrere seen during the 

 past year than formally, although this was found as a frequent 

 complication in animals suffering from distemper, tuberculosis or 

 enteritis. 



From our investigation of pneumonia, and clinical experience, 

 we are convinced that a large number of the pneumonic cases 

 which we meet with are due to a mixed infection, although the 

 specific organisms have not been definitely determined. It would 

 appear that the germs of pneumonia are not the same in all cases 

 of the disease, and for all genera of animals. A spherical or oval 

 coccus, arranged in pairs or short chains of four or more, as 

 well as a short rod-shaped bacillus with rounded ends, occurring 

 in pairs, are fairly constantly present. No animal inoculations 

 with these organisms have been made to determine their degree 

 of virulence. 



Tuberculosis. — Outside the Primate collection no cases of 

 tuberculosis have occurred during the past year. Our large 

 chimpanzee "Soko," which had lived in the Park for about six 

 years, died of generalized tuberculosis. Chimpanzee "August," 

 another old inmate of the Primate House, died from acute 

 tubercular pneumonia. This latter animal was a chronic suft'erer 

 from bronchitis, and on two occasions was seriously ill with 

 broncho-pneumonia, but he rallied well in both instances and 

 made good recoveries. Other cases of tuberculosis occurred in 

 the smaller monkeys. 



During the past year I have used the "Calmette Eyetest" for 

 the detection of occult tuberculosis in monkeys, ^^'hile as yet 

 my observations have not been extensive, still it appears to be a 

 most reliable method of detecting obscure cases of lymphatic 

 tuberculosis. The test was applied to a chimpanzee which had 

 just arrived, and the animal gave a typical reaction in six hours. 

 It lived several weeks and on autopsy showed extensive lymphatic 

 tuberculosis, the lungs being only moderately aft'ected. 



Since the lymphatic form of tuberculosis is the most difticult to 

 detect, this method, if future results are as successful as we hope, 

 will be of the greatest value to us in eliminating tuberculosis 

 from our collections. 



Distemper. — A few cases of this disease have occurred among 

 the small mammals during the year, but with isolation of the 

 infected animals and disinfection of the cages, the disease was 

 promptly controlled. A pair of Australian wild dogs, recent 

 arrivals from the National Zoological Park, contracted the dis-
