TWENTIETH ANNUAL REPORT (il 
REPORT OF THE VETERINARIAN. 
By W. Reid Blair, D. V. S. 
There has been no epidemic of any character among the 
mammal collection during the past year; however, a muck. larger 
number of animals have been received in a moribund condition, 
and this has resulted in increasing an otherwise low death-rate 
for the year. 
Among the important losses were the gorilla, the Indian 
elephant Gunda, the African elephant Congo, and a male orang. 
The gorilla Dinah died in July, after having been on exhibition 
about a year, from malnutrition and exhaustion. Perhaps no 
animal created so much interest among medical men as Dinah, 
who had been examined by scores of physicians. At no time 
during her illness did she exhibit signs of any acute affection. 
During the year she was subjected to the tuberculin test on 
three occasions, and in each instance the test was negative. The 
only definite symptoms exhibited were those of cage paralysis, 
and she showed great improvement for several months as the 
result of the administration of extracts of thyroid and thymus 
glands; tonics of arsenic, strychnin and iron, and being kept 
out-of-doors for a number of hours each day. The autopsy 
revealed no evidences of acute disease, except emaciation of the 
muscular tissue and changes in the bony structure similar to 
those seen in the early stages of osteomalacia or ‘“‘cage paralysis.” 
The pygmy elephant Congo was destroyed in October, since 
it was apparent that he could never again be exhibited on ac- 
count of the deformities of the joints which had produced a 
permanent lameness. Congo had for years suffered from 
chronic rheumatism, affecting the tendons and joints, but at 
various times seemed to be free from this trouble. In the past 
two years, during the summer months, he had been taken 
out of the Elephant House and placed in the southerly portion 
of the elk range where there is a small pond. The soft ground 
and mud, and out-door life greatly improved his condition, but 
soon after removal to his winter quarters, early in September, 
he showed evidences of severe inflammatory affection of the 
joints, with so much pain that it was decided that he should be 
humanely destroyed. 
The orang died as a result of a heart thrombus, after ex- 
hibiting symptoms of heart affection for three weeks. The 
autopsy showed an unusually large thrombus.
