March 17* 1955 Dr* Graham Edgar Ethyl Gasoline Corporation Chrysler Building Hew York City Hew York Dear Doctor Edgars I se no reason why carbon remover should not be used In the knock-testing engines I believe It would be wise to label the cans so as to indicate that the material Is not to be used for any other than the Intended purpose, and to warn against un necessary skin contact* The warning should be couched in such moderate terms as will not produce any undue alarm* However# such a' warning may contribute somewhat to reasonable care in its handling* I do not feel that it is necessary for me to specify the exact wording.
