Robert A, Kehoe, Director Kettering Laboratory of Applied Physiology College of Medicine, University of Cincinnati Eden '-venue Cincinnati 19, Ohio Dear Doctor Kehoe; May I express my sincere thanks for your long and most interesting letter. I confess that I have been rather reluctant to engage In such routine or commer cial 'work. On the other hand, conditions at the-Electric Storage battery Company are so bad, as you know, and Doctor Lanahan* s interest in improving these, conditions so strong that I wanted to-be of help'. -. - However* the ideas of the company differ so much from ours that we find it impossible to do the work for them. I will be glad, of course, to as sist them if they establish.a laboratory of their own. 1 have read your suggestions very carefully and find uyself practically In accord with them. I hope 1 do not Impose on you if I ask you for some additional infor mation. $hat method of collecting the urine samples do you recommend? I mean by this question how you overcome the inherent error due to collecting only one small -sample. Only recently, a have listened to a speech given by Doctor Hamlin in which he reported about strange findings which, in my opinion, result from the difference in sampling methods. Thanking you again, 1 am Very sincerely yours. K 0020001 H. Brleger, M. D.' Associate Professor and Director Division of Industrial Medicine
