April 8, 1938.
Dear May:
The official notification will of course go in the next few days.  This is a largely personal note to convey one or two comments, and, generally, my congratulations.  In the presentation of the item I referred to the fact that although the plans of the Institute tend to emphasize its its function as a center of interdepartmental research, it is clearly our understanding that the fields to be supported are psychology, psychiatry, sociology and anthropology, with some possibilities that there will be collaboration with or aid to such subjects as pediatrics, physiology, anatomy, economics, history, education and philosophy.  All of these subjects can be brought to focus upon the understanding of human behavior and that is the principal reason for which the present grant was made.
We have so fully discussed the numerous aspects of the Institute in the form of the aid which has just been voted, that I suppose no further comment is needed.  I do, however, want to express my permanent appreciation of the aid that has been given me since 1935 on this whole matter, and to thank you and ask you to thank all of your staff for the help they gave me in the undertaking.
With best regards and wishes for a profitable trip abroad for you and your family, and with real and continuing interest for what the Institute can accomplish in the future, I am
Yours sincerely,
Alan Gregg
