Kehoe University of Cincinnati The Kettering Laboratory College of Medicine - Eden Aveaue Cincinnati 19, Ohio Dear Dr. Kehoe: I was very glad to have the information given in your letter of March 31 and quite well appreciate the necessity to carry out the program as you have it constituted. Under the circumstances I think it would be more effective if d u Pont representatives postponed a visit to you until the exposure chamber is functional. Please advise us when the chamber is operating and we will hope then to arrange a satisfactory date for a visit. Yours very truly, TECHNICAL DIVISION HWE.lh H. W. DIRECTOR KF 0003312
