CO LW t It, President (Thompson \?ta-Meter Corporation A WHOUY-OWNEO SUBSIDIARY OF THOMPSON PRODUCTS, INC. PLEASE DIRECT REPLY TO C. H. VAN HARTESVELDT 6402 CEDAR AVENUE CLEVELAND 3. OHIO 2 3555 EUCLID AVENUE Cleveland 17, Ohio October 16, 1948 Robert A. Kehoe, M. D. University of Cincinnati Kettering Laboratory of Applied Physiology Eden Avenue Cincinnati 19, Ohio Dear Dr. Kehoe: Subsequent to our discussions of October 11th, 1948 I reviewed with Mr. M. S. Roush his calculations showing that considerably less tetraethyl lead will evaporate from the Vitol solution than from gasoline. His cal culations took into account the difference in volatility between gasoline and Vitol which accounts for the difference between his results and those put forward by Dr. Morgana. Mr. Roush will immediately run experiments to check the validity of his calculations. At the meeting to be held for discussion of the toxic properties of Vitol it is important that the following data he available: 1. Experimental results on evaporation of lead from Vitol solutions. 2. Data from guinea pig experiments conducted in your laboratory. 3. Data from re-examination of Yellow Cab, Sohio and Thompson personnel engaged in handling Vitol commercially and experimentally. 4. Data from examination of Columbus Green Cab personnel. It will be excellent if this meeting can be held sometime during the week of November 1st so that planning can be done prior to the American Petroleum Institute convention to be held the following week. Mr. Colwell is presenting a paper at that convention and I know a great many questions will be asked us concerning our plans for the future. If you can have the data available and come to Cleveland the week of November 1st, I will appre ciate a not from you to that effect so that others can be invited. Representatives of the Ethyl Corporation and the E. I. Du Pont De Nemours & Company will be invited to present any factual data they have Robert A. Kehoe, M. D. Kettering Laboratory Cincinnati, Ohio -2- 10/16/48 accumulated. However, it may be desirable to follow the general, fact presentation meeting with one at which plans for expansion could be considered. Oil companies requested to send representatives to the meeting will be the Ashland Oil and Refining Company, The Pure Oil Company, Standard Oil Company (Ohio) and the Shell Oil Company. With all best wishes. , Very truly yours, Cfi /^/ C. H. Van Hartesveldt CKVHssg ccr A. T. Colwell J. N. Cole gjs" 0020673
