important to a better understanding of the action
that certain drugs and internal secretions
have upon the nervous system. In the production
in animals of the analogue of neuroses, a
means of further understanding character or
behavior disturbances in man
is offered.
The Foundation appropriated $10,400 toward
the support of this work during the year beginning
August 1, 1935. The funds have been used
for the salaries of a research worker and laboratory
assistants, the purchase of equipment and
experimental animals, and-the maintenance of

University of Chicago
• Study of the Physiology of Sleep
For several years Dr. Nathaniel Kleitman, of
the Department of Physiology of the University
of Chicago, has been making a study of the
physiology of sleep. To enable Dr. Kleitman to
enlarge the scope of his work, The Rockefeller
Foundation made a grant of $6,300 to the university
to cover the cost of a special investigation
during the year beginning April 1,1935. This
project is in the nature of a test of a working
hypothesis of the mechanism of sleep, its onset,
duration, periodicity, phylogenetic development,
and adjustment to the twenty-four hour cycle
