and we have never felt the same confidence in passing 
these animals that we have in the case of the primates. 
This same statement applies to Black and White Lemur 
No. 18. 
Mandrill Baboons No. 21 and No. 22 were passed 
after the first injection to a separate cage. They were 
associated with Drill Baboon No. 7 before and at injec- 
tion. The charts were good. Probably infected at in- 
jection by the Drill and not far enough advanced to 
show changes at that test. Upon re-test at the general 
injection they were at once detected, killed, and found 
tuberculous. It would be desirable to hold over for re- 
test any monkeys which have passed the first test in 
those cases where they were associated, either in transit 
or at the laboratory, with condemned animals. This, 
however, would require unlimited resources, and would 
hardly be feasible where the animals were needed for 
exhibition. 
A group of four monkeys may be explained together. 
Vervet Monkey No. 23, Vervet Monkey No. 20, Mo- 
zambique Monkey No. 4, and Green Monkey No. 78 
were associated for fourteen months in the same cage. 
The green monkey had old, advanced lesions, easily a 
year old. He had been associated with the notorious 
Red Monkey No. 21 mentioned in last year's report, 
and doubtless infected the other three monkeys. 
Rhesus Macaque No. 148 died with old, advanced le- 
sions, and was associated with Common Macaque No. 
216, which died in isolation with insignificant lesions. 
The latter was doubtless infected by the Rhesus. 
Variegated Cebus No. 1 had been associated with four 
White-nosed Coatis which died tuberculous. 
Yellow Baboons No. 46 No. 48, and No. 49 had been 
associated. All of these monkeys had been associated 
with Long-armed Baboon No. 2, which died tuberculous, 
but were passed on a good chart after being associated 
with same. 
Guinea Baboon No. 64, White-throated Monkey No. 
12 and Chacma Baboon No. 11 had never been asso-
