Kehoe University of Cincinnati College of Medicine Cincinnati 21, Ohio Dear Bobs Attached is a copy of a letter we received here at the labora tory from Mr. C. E. Frudden, Consulting Engineer of the Tractor Division of the Allis-Chalmers Manufacturing Company. Mr. Frudden raises the question of possible health hazards in volved in allowing exhaust gases from leaded fuel to pass through hay or grain which when dried will be used for animal feed or human food. I have written to Mr. Frudden saying that the ques tion he raises is one which, I believe, should be referred to you for an opinion. If you will let me have the benefits of your thoughts on this matter, I will pass them on to Mr. Frudden. R.K.Scales/ja Att. 0009675
