Tobacco Documents Online

k Mr. (%. F'. McCornas Dr. R. N. DuFui s 'ay 27th, 195l~. ?We have a nropossl fro~: Dr. John :I. i;t;llor, Sect~cr~ of Medical Physics of Yale ~n:versits*, which I sr:EfTest that you transfer to Dr. Li tt2e. Dr. iieller feels, r?s a result of extensive research he has done in related fields, that there may be so:ne relstion between the cn7sical c:aaracteristics of tobacco smoke pnrticles and their efftct on the reticulo- endothelial system in the lung. He has some reason to believe that only particles of certain size Pnd electrical charge can be absorbed in the lung. T;ierefore, it might be possible to devise a filter which would remove those particles which, becquse of their s3 ze an~d charge, are capable of being, absorbed. We feol that this is an intexasti.ng^'- and possibly n val- uable theory. Dr. :Iellor has sent us sevcrr:l papers, written by himself and others in this field, which we have studi ed; however, -wcs do not feelt that ue sre campletely co^ify©tent to J;udge the theory, and would therefore, like to h-ave advf ce fro:n others on its possi ble value. Dr. I-er ler states that certain reser.rctl, under the spon- sorship of the Atomic Energy Commiss.Ior., has reference to his theory snd tends to strengthen it. I wo1ild like to suggest that Dr. Li ttie, Dr. iioller and 'T discuss this matter to determine whether its exploration can be of interest to the ?.I.R.C. I am holding t'ie rapers which Dr. lieller sent 13 until we dQtormine whetaer Dr. Little would like to enter =::t,o sucri a aiscussion. I AM lookinrr forward to :neetin g Dr. Little and ciiscussInp t')isAnd other mn tters s~ith ':iim. Very truly yours, Ii-. N'. D, ~ Pui s ~ R7 @NDuP:ece ~ r%i W C54-00614 ~ I= LQ M ~
