Kehoe Kettering Laboratory of Applied Physiology University of Cincinnati Cincinnati, Ohio Dear Doctor Kehoe: I have before me a letter from your secretary ciated December 20, 1939, and I must ask your pardon for this tardy reply. </ In answer tojour question, we do have containers for both urine ana "/'^samples, and also the outfit for taking blood samples, but if possible I would like to keep these here at the Plant Hospital as one never knows when the occasion may arise for putting them to use in a hurry. Along this line it might be said that it has been rather gratifying to see the way the number of complaints referable to fumes and acid, etc. have dropped off since the general ventilation picture has been improved. Are you by any chance familiar with the work of a Doctor R. B. H. Gradwohl in St. Louis, Missouri, who has written a largq and heavy book on laboratory procedure and diagnosis? He is an advocate of the so-called "thick drop" methods of staining blood for examination in an attempt to determine lead absorption, and I would like your opinion as to whether or not this is worth looking into or whether you feel that we should be content with our stipple cell examination alone. We are following the same procedure on them that was in use when you were here with Mr. Duval in 1937. The first part of November last year I was at Dayton for three days at our General Motors Physicians * Conference, and I thought that perhaps I would be able to make a flying trip to Cincinnati to visit your laboratories, but as is the case with most of these meetings every minute day and night seemed to be filled and I did not make it. Mrs. Hillenbrand, however, drove the car aown to Cincinnati one day with the wife of one of the Hr 0 013 G1G N17505 HARRJSOJi Dr. Robert A.

She was most enthusiastic about it and I was truly sorry that I could not get over to see your city. I shall be glad to hear from you soon and hope that we may have the pleasure of having you pay us a visit in the near future. Yours very truly HARRISOR RADIATOR DIVISION GENERAL MOTORS CORPORATION Plant Physician
