1909. | TUBERCULIN TEST IN MONKEYS. 87 
The history of this case,a male Cercocebus fuliginosus (Number 
59), is interesting, not only because it was one of the first lot 
tested, but as an example of the need for unceasing vigilance. It 
reached the Gardens on March 29th, 1905, and had a temperature 
taken almost daily until June 28th, the range being from 100-6? 
to 103°8°. On the last date it was injected and gave a twenty- 
four hour temperature which appears good, but not being fully 
understood the animal was held over and reinjected on August 8th, 
at which time it was passed, again on a twenty-four hour record. 
In January 1906 it seemed unwell and was returned to the 
Laboratory for retesting, on which occasion the forty-eight hour 
chart was good, with trifling irregularities. It was kept under 
observation until March 6th, when it was returned to the Monkey 
House. Later in that month three others of the same species, 
originally passed in December 1905, were removed for retesting 
and found to be tuberculous, one of them (No. 62) having been the 
source of infection, as is indicated by present reading of the charts. 
Number 59 remained on exhibition in apparently good health for 
nineteen months, until October 16th, 1907, when it was removed to 
the Laboratory, dying three days later with general tuberculosis. 
After March 1906 this animal was not exposed to infection from 
other monkeys, and it is probable that it contracted the disease at 
that time from its three cage-mates, which were found to be 
tuberculous several weeks after its return.

Progress of the disease is usually much more rapid with 
monkeys than in this subject, and it is of course possible that it 
may have been a sporadic case communicated by human agency.
