HELPER8TOPBR8TRifi8E 4 Mr.Robert A.Kehoe, University of Cincinnati, College of Medicine, General Hospital. Dear Sir I really have to apologize for not having reacted sooner to your letter and to the special co pies of your papers on lead poisoning and its pre vention. I gladly take this opportunity to thank you for these papers which I have perused with the greatest of interest. fhere is nothing of interest that I could report to you in connection with my activity on behalf of the Ethyl Report Corporation. In the course of the one year past there have been no cases of poisoning end the number of mixtures made has been relatively small owing to the newness of the matter in Central Europe. You will probably be inter ested to hear that the average condition of the teeth of the Czech labourers is so bad that the majority of the people proposed had to be refused as unfit for the handling of ethyl fluid. V/ith a view to the instructions issued by the Ethyl Export Corporation I have been guided accordingly although according to the opinion prevalent in Austria the danger of lead poisoning by inhalation is considered greater than by oral intoxication. In Austria the State Health Authorities are beginning to interest themselves in ethyl mixtures and. the possible damages to labourers resulting from the same. I1 he chief of the Industrial Hygienic De partment of the State Health Department, Eofrat Professor Mr.Ernst Brezina, a recognized evnert in the 00135' field of industrial hygiene, has inspected the Kaaran plant during the last few days and I have had the opportunity of thoroughly discussing with him all protective arrangements. Insofar as they re ferred to the mixing plant he has considered them to be sufficient and practicable in every respect. .is concerns the question of a possible danger to those persons handling the ready ethyl gasoline, such as station operators etc., the question is some what different. I would be very much obliged to you indeed, if you could answer some questions in this connection for my own information, as well as for the information of the State Health Inspectors. In this regard 1 beg to refer to the postscript to your letter of .ipril 2nd 1935, advising, that you would send to me a study on the lead absorption of filling station and garage mechanics. Y/hich dangers exist for those persons handling ethyl gasoline ? Ire there many cases of lead poisoning of those persons ? Y/hich preventive measures are oustomnry in America or which prevent ive measures are required by the authorities ? Here there is rather a tendency of seeing consider able danger in the handling of ethyl gasoline and of probably requiring protective measures and pe riodical medical examinations by the .authorities, all of which may hinder the distribution of ethyl vaseline and may affect the commercial rentability. Aien replying to my questions kindly consider that i intend to show your letter to Professor Hrezina with whom I am on friendly terms since many years and wno regards you as the first expert in t ne field of tetra ethyl lead poisoning. 1 hope that my request will not cause you -:.y undue inconvenience and'ask you to accept my best thanks beforehand. Yours very truly Kf 0013553
