PA. \ Tovember 5, 1923. .<4^ SUBJECT: Physiological Effects of Ethyl Gas. - tf Dear Dr. lintf: (7 Replying to your letter of November 3: tief'irnTsL I purposely avoided the use of "lead" in the inter bureau correspondence on this subject because of the fact that even in confidential investigations the Washington Office some times slips out information to the newspapers. It was in our cooperative agreement that there should be no publicity on this investigation until it was completed and the final report pub I lished. If it should happen to get some publicity accidentally, it would not be so bad if the word "lead" were omitted as this term is apt to prejudice somewhat against its use. In our re port for publication we will, of course, use the correct term. In interbureau correspondence the trade name is an easy term to use and I do not see where it will cause any trouble. Very truly yours, \ cc Dr. Lyon File A. C. Fieldner. Y*O * uovo W23 s. c. u h $. /ROTES' ( NOV 6 ,1923 m Jv
