INTERNATIONAL HEALTH DIVISION 39
A simple method has been devised for detecting
the eggs of Anopheles in the breeding places
of mosquitoes. A thumbless mitten or bag of
white cloth isworn on the left hand; the surface
of the water is skimmed with a pan, and the contents
of the pan are strained through the mitten.
The material collected on the mitten is examined
immediately with a hand lens. The usefulness of
this method is greatest in regions where the eggs
of Anopheles are easily identified. In parts of
Europe where A. elutus^ A. maculipennis, and
A. superpictus are found, the method has proved
very practical.
In the United States a field study is at present
being carried on at the station located in Tallahassee,
Florida, where malaria naturally induced
for its therapeutic effects is being studied with
the cooperation of the Florida State Hospital at
Chattahoochee. Important work in both avian
and simian malaria is being continued with
Foundation aid by Dr. W. H. Taliaferro of the
University of Chicago. Thus far the principles
involved in infections in birds have been found
to be the same as those in mammals, but the
time relationships are entirely different. Everything
is speeded up in birds, but general principles
from bird work can be applied almost
directly to monkey infections and these in turn
are probably directly applicable to man.
