PREFACE. 



The experimental results presented in this monograph supplement 

 and amplify the published work of Dodge and Benedict on the Psycho- 

 logical Effects of Alcohol, and form another contribution on the psycho- 

 logical side under the tentative plan for alcohol investigation at the 

 Nutrition Laboratory. It is a pleasure to acknowledge my obligation 

 to the above investigators, both of whom generously spent much 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. Darling. 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.
