Redden, I should explain to him that there lias been a suspicion (which has not been verified by any facts) that the absorption of tetraethyl lead added to gasoline if handled carelessly, might in due time give rise to chronic lead poisoning; that in view of this suspicion careful investigations have been made among men and upon animals to determine whether or not there 13 any likelihood of thi3 occurrence; that no evidence whatever has been found that lead absorption in appreciable quantities occurs under these conditions; that, in spite of that fact, however, the Ethyl Gasoline Corporation has made it a matter of policy to educate gasoline handlers not to use Ethyl gasoline in cleansing tools or for any other purpose which brought about unnecessary contact of the skin with the gasoline, and that it looks with disfavor and #2 Mr# E l Webb January 10, 1928 discourages the use of Bthyl gasoline In the way suggested in his letter largely because encouragement of such procedure would tend to offset the attempts which had been made (not only by the Ethyl Gasoline Corporation, but'by the United States Public Health ^ervice) to educate gasoline handlers in the avoidance of any unneces sary contact not only with Ethyl gasoline but with materials which are intended purely for use as motor fuels# If you do not wish to make your suggestion as strong as I have outlined above, it will be a very simple matter merely to set forth the facts and allow Dr Redden:to make whatever application of them he chooses, on his own responsibility.
