Kehoe University of Cincinnati Department of Preventive Medicine and Industrial Health The Kettering Laboratory College of Medicine - Eden Avenue Cincinnati 19# Ohio Dear Dr. Kehoe: In connection with the discussions on trimethylethyl lead# it has been decided that I should develop this with you and then transmit the information to those who might be interested#within the company. It would appear to me that this might be done in either one of two ways. You might either let me have information you have in the letter or I could arrange to come to Cincinnati# at your convenience# and you could discuss this information with me at that time. I will leave it up to your discretion as to which way you feel it would be best to handle this. If you recommend my making a trip to Cincinnati I will leave the date up to you. At the moment# the following dates would be impossible for me to come to Cincinnati: June 13, l4, 15# 18# 20# 25-29- Sincerely yours# REE:cjh R. E. ECKARDT, M. D
