The experimental results presented in this monograph supplement
and amplify the published work of Dodge and Benedict on the Psycho-
logical Effects ofAlcohol, andformanother contribution on the psycho- side under the tentative plan for alcohol investigation at the
Nutrition Laboratory. It is a pleasure to acknowledgemy obhgation
to the above investigators, both of whom generously spentmuch time
counseling with me on various phases of the work.
The report has had the further advantage of the competent editorial
supervision of Miss A. N. Darhng. I was assisted in the experiments
by Mr. E. S. Mills and in the preparation of the alcohol and control
doses by Miss E. B. Babcock.
