INDUSTRIES PPG INDUSTRIES, INC./ONE GATEWAY CENTER/PITTSBURGH, PENNSYLVANIA 15222 AREA 412/434-3719 May 13, 1971 ELMER C. LARSEN, Vice President General Manager, Coatings and Resins Division Mr. R. A. Kehoe, M. D. Kettering Laboratory College of Medicine University of Cincinnati Cincinnati, Ohio 45219 Dear Doctor Kehoe: Dr. Lee B. Grant, our Corporate Medical Director, has told me that on rather short notice you were able to rearrange your busy schedule to assist us in reviewing the medical and environmental facts associated with the alleged relationship between an illness suffered by a painter and his use of our product, Pitt Glaze. Dr. Grant said that your review of these facts indicated to you that a causal relationship did not exist in this case and that you testified to this belief very effectively. Certainly the verdict of "Not Guilty" was eloquent testimony as to the effectiveness of your ability as an expert witness. I would like to both thank you and express my appreciation for your valuable assistance in this matter. Sincerely, Elmer C. Larsen N22419
