November ?,1923.0CL-R8J1 Superintendent, U.5.Bureau of Mines, Pittsburg, Pa. --7A SUBJECTi Physiological Effects of Ethyl Gas Bear Ur. Flo In tho Ulnutes of your Problem Conferno of the Cheadool Division, Qotobor 27, 1 not under B169, the above title, and X believe that 1 recall that UIdgiiy toll me bis Company had decided to adopt the trade name ''othyl gas." Of course, their objects in doing so are fairly clear, and among other things they aro not particularly desirous of having the name "lead" appear in this oase. That is alright frost the standpoint of the aeneral Motors Company, but it is quite a question in sty mind as to whether the Bureau of Mines would be justified in adopting this name so early in the gome before it has hod the support of popular usage. The reasons for tqy objection are as followsi (1) it will lead to oonfuslon, especially If the noise ever beoomesjw^d^^nsed, as there are many other ethyl gases besides^totraetigrl leedt (2) since the real ob ject of our Imrestigotion is to determine whether or not lead is deleterious in the combustion produote, it Beans to me that we would be wise in our investigations to refer to its ohemlo&l name "tetraethyl lead", or one of the other ones possible. This is merely sy personal feeling, and 1 am open to conviction. If you do not shunt it, X would like to hear from you further. Very truly yours. oo to Dtr. Lyon S.C.Llnd Chief Chemist
