Kehoe, College of Medicine, University of Cincinnati, Eden & Bethesda Aves, Cincinnati, Ohio. My dear Kehoe: fie have been requested by one of our Licensees to furnish him some of our carbon remover for use in the knock testing engines. In this use, an ounce or so of the fluid is poured into the spark plug hole and allowed to stand over night. Please advise me as to whether you think we should fill such an order and if so, what label we should be on the cans. This would, of course, be essentially experimental use and would not involve exposure to the fluid other than by carelessness or accident. We would, of course, not do this generally, but it is possible that some fifty engines might eventually be treated"in this way. Very trul ge/lrj KE 0015542
