TWENTY-FOURTH ANNUAL REPORT IIL 
Weather.—The influence of the unusually heavy and pro- 
longed rainy season was to place emphasis on laboratory work 
during the first three months. But again we proved that no 
vagary of tropical weather or seasons need interfere with con- 
tinued, intensive research. 
Results Achieved for the Zoological Park.—Influenza has 
worked havoc among the Indians of the interior of Guiana and 
this year almost none came down on their annual trading expedi- 
tions. Our chief source of supply of live birds and animals was 
thus cut off, but we were able to secure more than thirty interest- 
ing specimens among which were a white collared hawk, a five 
foot iguana, an armored catfish, and a splendid cock-of-the-rock, 
which is still in perfect health. 
A collection of living animals including a jaguar, ocelot, 
three capybaras, four golden agoutis, four anacondas, and a 
jabiru, was deflected from shipment to London and purchased 
in New York for the Zoological Park. 
Results Achieved for the American Museum.—Without in 
any way interfering with the work of the Station it was found 
possible to collect and preserve a collection of two hundred and 
seven mammals, skins, skulls and skeletons, with full data, com- 
prising about forty-three species. Among these was a series of 
thirteen red howling monkeys of various ages for use in a 
group. 
Every reptile and amphibian, except those involved in re- 
search problems, was preserved, a collection of two hundred 
being brought north to the Museum. 
A series of crocodile skulls being requested by Professor Os- 
born for immediate use, five were collected and sent to the 
Museum. 
Results Achieved for the Carnegie Institution.—Constant 
high water made it impossible to use poison and thus obtain large 
numbers of electric eels for Professor Dahlgren, but several were 
caught in nets and preserved and the work will be carried out 
next year. 
By request, twin embryo red howling monkeys were sent 
to Dr. Adolph H. Schultz of Johns Hopkins University for study.
