part of the hydrogen may be replaced by heavy
hydrogen, and this part used as a marker. An
extensive program for research on fat metabolism
has been outlined. Numerous experiments are
under way on the effect of various concentrations
of heavy water upon biological processes.
It is this work which will be continued under the
present grant. A Foundation grant in 1934
provided $10,000 for the purchase of heavy
water. Professor Urey expects to have on hand
for next year about two gallons of pure deuterium
oxide which will be sufficient for the experiments
in both chemistry and biology.
National Research Council
Committee on Effects of Radiation on
Living Organisms
During the year there was appropriated the
sum of 275,000 to the National Research Council
for expenditure and allocation, or both, by
the Committee on Effects of Radiation on Living
Organisms during the three-year period
July 1,1935, to June 30,1938. Aid was formerly
given this committee by the General Education
Board. The study of various types of radiation
(x-ray., radium,
ultra-violet, infra-red, etc.)
offers a most promising avenue of attack,
through the physical sciences, upon various important
problems of biology. In the past the
radiation committee referred to above has
