MEDICAL DIRECTOR July 2k, 1957 Robert A. Kehoe, M.D. Hie Kettering Laboratory College of Medicine - Eden Avenue Cincinnati 19# Ohio 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 nyself and your people will not stand in the way of our mutual respect and friendship. Very truly yours. /&V D. .
