SCHREYER April 7, 1956 Product Service and Safety Section Ethyl Corporation 100 Park Avenue New York 17, New York Gentlemen* Our automotive section is presently studying the use of your experimental Anti-Knock Compound AK-33-X. It is my understanding that a brochure is available on the properties of this substance entitled "Laboratory Use of Ethyl AntiKnock Compound, Experimental AK-33-X". Would you be so kind as to send me a copy of the above mentioned material. Since I am especially interested in the toxicological aspects of the use of AK-33-X, I would also appreciate any additional infor mation on this product which may be available to include range finding toxic studies on animals relative to respiratory, gastro intestinal and skin absorption -as well as skin and eye irritation. A statement of human experience with AK-33-X including any warning characteristics, injuries from any type of exposure and suggested treatment would be appreciated. I appreciate the fact that informa tion relative to animal and human exposure may still be fragmentary and under study, therefore, I would appreciate being kept up to date on these developments as they progress and the commercial properties of AK-33-X are further explored. Cordially yours, LBslbf Lamson Blaney, H.D. Medical Director tfjf 001S318
