Kehoe wearing Laboratory of Applied Physiology .ijn -^venue jincinnati, Ohio Dear Dr. Kehoe: ',7e are sending to you today via parcel post, special delivery, the urine samples which were collected in accordance with your letter of June lf?th. We also have taken or are taking steps to put into effect the other suggestions you have made for the safe handling of TEL. During your visit here, you mentioned specifications for rubber gloves to be used in handling the equipment. You expressed the opinion that the large glove we have on hand would be suitable but we should like to have the specifications for use in placing future orders. Insofar as the work is concerned it is proceeding satisfactorily. Y/e find the reaction proceeds nicely. Our problem now is the fractional distillation of the reaction mixture. Y/e believe the TSL is completely used up and we are doing some work to prove this Another problem we forsee is the disposal of the lead chloride, formed in the reaction to the extent of 84% of the TEL used. The lead chloride seems to be of high purity and should have some value. We will await word from your Hew York office before placing any orders, and will keep you informed of developments in this respect. Y/e appreciate very much the suggestions you have made and the technical information you have obtained for us. The information on the decomposition of TEL is sufficiently informative for our purposes. Sincerely yours, THE LAKE ERIE CHEMICAL COMPANY X L . E. Edelman Director of Research
