Dear Colonel Gentzkow: if are sending herewith three copies of the discussion and review of `'Gasoline Intoxication". As you requested, this was drawn up in some detail and a great isany more references have been included than will be contained in the finished paper* I propose soon to condense this material considerably and publish it in one of the journals. Largely as a consequence of the detail included and to a degree because of the large amount of material that had to be gone over, this paper will permit of considerable reduction should you wish to use all or any part of it for purposes of information in the Army Ledleal Corps. * The work on the stove is practically at completion. Two runs of 4 to 6 hours each were made initially, then the stove was operated daily for a period of some weakc, and a third balance experiment carried out. Our recoveries have been f ro m 9& bo 100$, well within the limits of experimental' error, and several matters of practical significance have developed from this work. It would appear that when leaded gasoline that contains 3 co of lead la used measurable amounts of load ore found in the flue gases, but that the greater proportion of this comes.over in the first 30 minutes while the stove is coming to temperature, and we have further found that the lead which passes tbe filter in the' early minutes of running ia in the form of tetraethyl lead. This of course does not escape into the flue gas as it is completely decomposed in passage through the flame, but it does suggest the possibility that improvements In the stove could bo made that would enable more complete decomposition of the tetraethyl lead while the stove is being started. . Dome items in connection with this and the matter of the amounts of lead found in the flue gas make it seem advisable that re discuss this matter together as soon as all of our analytical data ic at hand.

G* - (2) - w&roh 2g, 19 ^ 1 It happens that Dr. Kohoe and I will bo in the east in the second week in April and it would be possible for us both to atop off at Washington on I'riday, April 1 1 . This happens to be Good Friday and m y sot be a oonvenlent day for you. On the other hand it will be one of the few times witn it will be possible for us to have Dr. Xehoe sit in on this meeting and I think it would be m a t desirable to have his opinion at the time we go over the data. ?fill you. therefore* please let me know as soon as convenient, whether or not it will be possible for ua to see you on April 11. Ohould that date not be convenient, will you net e<me other time. I shell look forward to seeing you. Best I'egards. Cordially, ;M:vr Willard Kaohie, K . ii. HE 0 0 0 3 5 0 4
