SECTION II. 
Tuberculin Test and Tuberculosis. 
At the time of our last report there were seven monkeys 
held in the detention room for retesting. During the 
year thirty-two monkeys have been tested for tuber- 
culosis by the subcutaneous tuberculin injection. Of 
these twenty were new arrivals. Eighteen animals 
were passed unconditionally and nine were considered 
as suspicious enough to segregate yet too good either as 
specimens or as regards their temperature charts, to 
hold in the quarantine rooms. They were passed to 
separate outside cages. There have been twenty deaths 
among the monkeys this year of which three were mon- 
keys injected during the same period. From the exhibi- 
tion specimens either in the large house or outside cages 
no case of tuberculosis was found. Two cases of tuber- 
culosis have been discovered but neither animal was 
passed to any cage away from the detention rooms. 
Rhesus Macaque No. 168 was received early in April 
and injected on the 21st of that month. Having given 
a poor chart he was held in detention with Rhesus 
Macaques No. 166 and No. 167. Other monkeys 
arriving at the same time, Rhesus Macaques Nos. 163, 
164 and 165, passed at the first injection. Nos. 163, 
164 and 166 still live and appear well. Nos. 165 
and 167 are dead but failed to show any tuberculosis. 
The condition of No. 168 was poor but it did not 
seem to be tuberculous. Since he was not fit for 
injection he was held at the laboratory until he died 
June 21. • No animal with which he came in contact 
has developed tuberculosis. Weeper Cebus No. 64 
was received April 24 and on account of his poor 
physical condition was kept away from the others and 
remained so until killed. He gave two questionable 
charts and one bad one, after which he was killed. One 
small caseous retroperitoneal gland was found, so that 
he should not have been infective. He was only asso-
