October 2JS 1935 Dr* Graham Edgar Ethyl Gasoline Corporation Chrysler Ballding Hew York City New York Asar Edgart I am enclosing herewith the original table a copy of which appears in the last report on the Ethyl Gasoline problem* I append to it your letter and the report sent me from which these data were compiled You will remember that we questioned particular ly the figures for 1929 and it occurs to me that since I am getting the material together for an article to be published, in the Journal -of Industrial Hygiene (if they will accept it), that it might be well to have these figures as accurate as they can be obtained* In checking over the figures which I inserted under 1929, I find that what I did was to take the figures given in the report and to double them* Recognising that the first six months include the season of poorest gasoline distribution, I assumed evidently that the nest three months were given an approximately equivalent volume of distribution and, therefore, set down twice the amount for the nine months period* .
