The following animals were sold during 1916: 
6 axis deer; 1 Indian sambar deer; 5 wapiti; 3 fallow deer ; 
1 pair raccoon dogs, and 1 kinkajou. 
The Zoological Room of the Washington Irving High School

REPORT OF THE VETERINARIAN OF THE ZOOLOGICAL PARK. 
By W. Reid Blair, D. V. S. 
The total number of deaths during the year was less than 
during 1915, even though our losses included a considerable 
number of aged antelope and deer that had been exhibited in 
our collections for from ten to fourteen years. In most instances 
these animals did not die as the result of acute disease, but were 
destroyed on account of general debility that had rendered them 
unfit for further exhibition in our collections. 
Among the animals destroyed that had been on constant 
exhibition for twelve or more years were: two American bison, 
a sing-sing waterbuck, sloth bear, Indian sambar deer, bara- 
singha deer, American wapiti, female nylghai, and a markhor. 
The new Animal Hospital is now in use. Fortunately few 
cases of illness have developed since it became available, so that 
its utility, as yet, has not been tested to the utmost. . The Joseph 
collection of Australian animals was quarantined in the new 
building, as well as a part of the shipment of animals received 
from South Africa in charge of Mr. Loring. 
The building has been available also for the isolation and 
observation of suspicious cases of infectious or contagious dis- 
eases, that have occurred among our collections during the win- 
ter. The prompt isolation of two cases of suspected distemper, 
that were detected in the early stages, checked a dreaded disease 
for which we are constantly on the lookout.
