Dear Dr. Kehoe: Thank you for your letter of July 9, 1957* I am sorry to learn that there apparently are no records available from you concerning Mr. Floyd Butler which would indicate in a positive way a normal or abnormal hemoglobin or other blood evaluations. I hope as you do that the exchange of rather sharp letters between ny self and your people will not stand in the way of our mutual respect and friendship. ' IWC/bjy Very truly yours, r&v ` w` D. .
