February 15, 1945 Major F. V. Schroeder, P. 0. Box 87, Glenview, Illinois. My dear Major Schroeder! I am afraid it will be a little difficult for me to give much useful information or advice in response to your letter of February 5. At this distance and with the information you have given me, I cannot arrive at any conclusion concerning the nature of your illness, and this makes it quite impossible fox* me to express any opinion as to its cause or its treatment. I may say, however, that I consider it very unlikely that you have suffered any injury of a permanent sort as the result of any exposure to gasoline containing tetraethyl lead. Moreover, I doubt very much if any permanent injury could have resultedfrom breathing the air in the cockpit of a plane, even though this air should have been contaminated with exhaust gases. I feel quite certain that no injurious effect of a prolonged character would have resulted from such exposure, unless you have been entirely overcome and rendered completely unconsicous by carbon monoxide poisoning. However, no useful pur pose will be served by my making a series of guesses about your condition or its cause. It seems likely to me that you have had a physician examine you and that such a physician could give me detailed information on your present condition. If this could be cone, either by your physician or by yourself through him, I might then be able to have an opinion which might be useful to you- In that case I should be very glad to hear from you or your doctor, and I will do my best to give you my opinion and advice. Sincerely yours. I'AK ef Aobert A. Kerioe, M. F-5'
