ciated with one monkey, Rhesus Macaque No. 156 
which is held in quarantine because it harbors an in- 
testinal worm, but it has failed on several occasions to 
give a tuberculin reaction. Rhesus Macaque No. 156, 
two Black Handed Spider Monkeys and Weeper Cebus 
No. 65 are now held in the laboratory for retesting.

It would seem from this year's records that the expense 
and trouble of the general injection of 1912 were justified, 
because no infection has arisen in the collection. 
The two monkeys immunized and presented by Dr. 
G. B. Webb of Colorado are still in the monkey house, 
well and growing. 
During the year there have been 30 cases of tuber- 
culosis outside the Primates. Among the Ungulates 
we lost a Mountain Zebra with a lesion, apparently 
primary, about the head of the cecum extending up- 
ward to the mesenteric root glands behind the crura of 
the diaphragm to the lung, and downward along the 
brim of the pelvis following the arteries and nerves to 
the gluteal muscles, the fascias and bursa of the ankle. 
The mate of this animal was not infected. Among the 
Rodentia we lost one beaver which was tested by tuber-
