Deer House during the past year, and is now in fine condition, 
The same is true of a number of other animals. 
Pneumonia.—Fewer cases of pneumonia were 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 sufferer 
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. While 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 affected. 
Since the lymphatic form of tuberculosis is the most difficult 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 
promptiy controlled. A pair of Australian wild dogs, recent 
arrivals from the National Zoological Park, contracted the dis-
