Dear 4r. Leopold: 
The name and address of the doctor about 
whom I spoke to you at the Game Conference is 
Dr. Weston A. Price, (D.D.S., M.S., F.A.C.D.), Dental' 
Research Laboratory, 8926 Euclid Ave., Cleveland, Ohio. 
If you write to him, you will want to ask 
for the report of his investigations of calcium and 
phosphorous levels or ratio in food substances, parti- 
cularly milk and butter and their utilization in health 
and disease, with particular reference to the plants 
which he found were being used by certain cows which 
produced milk of high quality in this respect. 
With best wishes for a good break in a new 
deal, if one is inevitable, and hoping that you will keep 
me in touch with any changes which you may make, I am 
Very truly yours, 
Arthur L. Clark, DIRECTOR 
GAME RESTORATION DEPARTMENT
