It had general tuberculosis. Moloney's Monkey No. 1 was 
tested twice and pronounced healthy. He died in the 
Monkey House on February 14, 1910, of intussusception 
and acute peritonitis, but without evidence of tuberculosis. 
The monkeys returned from the keeper's room, three Mon- 
goose Lemurs and a Black Ape, were tested twice during the 
next three months. The Lemurs passed both tests and are 
now in the exhibition cages. The Black Ape had a ques- 
tionable temperature chart after both injections and was 
finally killed, but showed no evidence of tuberculosis. 
Since Anubis Baboon No. 39 was found to be tuberculous, 
11 monkeys (aside from those described above) have died in 
the exhibition cages. No one has shown tuberculosis. 
Before this outbreak there had been no deaths from tuber- 
culosis in the Monkey House since October, 1907. The im- 
mediate removal to the laboratory of all animals which had 
come in contact with Anubis Baboon No. 39, and their re- 
testing, seems to have stamped out the disease. The possi- 
bility of allowing an infected animal to slip through occasion- 
ally has never been underestimated, but our experience in 
controlling the spread of the disease by removing all exposed 
animals and their rigid retesting has in reahty strengthened 
our confidence in the tuberculin test. In reviewing the tem- 
perature of monkeys after tuberculin injection, great atten- 
tion is paid to irregularities. Charts not following closely 
the general courses given in our pubUshed reports of this 
work are marked as unsatisfactory and the animals held for 
retesting, some three and four times. To our strictness in 
this respect we attribute our few failures. 
Parasites. 
Spiroptera incerta in Psittaci. 
These parasites have not been nearly so common this 
year. In 1907 there were 18, in 1908, 21 and 1909, 24. 
This year only 9 parrots showed these worms. They were 
Rosehill Parrakeet, 3; St. Thomas, 1; Pennant's Parrakeet, 
2 ; Redsided Eclectus, 1 ; Grand Eclectus, 1 ; Brown Fronted 
Macaw, 1. Seven of these occurred in the first six months
