SECTION II. 
Tuberculin Tests and Tuberculosis. 
The quarantine rooms held no monkeys at the beginning 
of the year for which this report is made, but 13 new 
specimens were received and 22 old ones were returned 
for various reasons, thus making a total of 35 tuberculin 
tests for the year. The mortality among the primates is 
22 or 26% of exhibition specimens.

Only one case of tuberculosis occurred among our 
exhibition specimens and for that I cannot account 
otherwise than as a visitor infection. It seems impossible 
that it could have been a long case with latency and 
sudden or rapid development for a short time before 
death, as the monkey concerned. Sooty Mangabey, has 
notoriously no resistance to the disease and progresses 
rapidly to a fatal outcome when once infected. This 
specimen (Sooty Mangabey 74) was received 5/13/13 
and passed on a good chart to a cage where no tuberculous 
monkeys were or subsequently developed. It was 
returned to the quarantine rooms at the time of the general 
injection in 1914 and was passed to an outside cage whence 
it was returned to the laboratory and then to the monkey
