SECTION II. 
Tuberculin Test and Tuberculosis. 
Four old monkeys remained in the quarantine rooms 
at the time of the last report; during the year twenty 
new monkeys and lemurs have been received and tested, 
and during the late summer and autumn all the animals 
in the large exhibition house were retested. By this 
general test seven suspicious animals were discovered, 
two Rhesus Macaques presented by Dr. G. B. Webb 
(further reference below), a Mandrill Baboon, two Brown 
Macaques, a Red and a Green Monkey. The last four 
were put into outdoor cages. The Mandrill was also 
passed to an outside cage, but was retested and returned 
to the large house two months later on account of the 
cold; he is now in good condition. 
In January, 1913, Dr. G. B. Webb, of Colorado Springs, 
sent us two monkeys from his experimental series, one 
having been treated with a number of injections of living 
tubercle bacilli and considered immune because it did 
not react to a subcutaneous injection of tuberculin, the 
other having received only one injection and to be used 
as a control. These monkeys were to be exhibited in 
our general house, exposed to infection just as our own 
specimens, to test their immunity. A tuberculin test 
was given on their arrival and as they did not react they 
were passed to a separate cage in the Monkey House, 
where they remained from January 12th, 1913, to May 
19th, 1914, when one was noticed to cough, and they 
were both removed to an outside cage. A retest was 
made in July, 1914, and as one was very suspicious and 
the other not acceptable in temperature curve, both 
were killed. The animal treated for several injections 
was found to have advanced generalized tuberculosis, 
while the other was free of the disease. It is, however, 
noteworthy that the lesions in the tuberculous animal 
were much more fibrous than is common in tubercu-
