The Bananas supplied to the Monkeys are brought direct 
from the wharf and during transit are doubtless handled 
by persons suffering with tuberculosis. It has been sug- 
gested that they might present a means by which tuber- 
culosis was contracted by Monkeys. In order to determine 
whether an organism having the morphology and tinctorial 
properties of the tubercle bacilli could be found upon the skin 
of these bananas, eight large ones were cut from the stems 
and washed in sterile freshly distilled water. This washwater 
was centrifuged with a small quantity of alcohol, the sedi- 
ment collected and dried on slides. It w^as stained with 
carbol-fuchsin and decolorized by a saturated solution of 
methylene blue in absolute alcohol. A search of two and 
one half hours over these slides failed to reveal any alcohol 
fast organisms. 
Parasites. 
There have been many animal parasites found in our 
post mortems this year, a few of which will prove of unusual 
interest. Dr. F. D. Weidman, who started with us early in 
January, 1911, is paying particular attention to them, and 
will proceed with a special investigation of the long filarial 
worms found among the muscles and beneath the skin of 
wild cats. In one of these animals he has already found 
larvae in the blood, seemingly young forms of the muscle 
filaria. Dr. Allen J. Smith still receives the worms from the 
autopsies, and has reported some of them. Routine blood 
examinations of all animals from which fluid blood could be
