Kehoe University of Cincinnati College of Medicine Cincinnati, Ohio Dear Doctor: At the conclusion of our conversation the other day we met Dr, Blankenhorn for a discussion of the Daye case. I believe Dr. Blankenborn*s views are exactly in agreement with your own, that is that with a possible exception of Benzol, there is no chemical etiology for lymphatic leukemia. Benzol alone has been judged to be a possible cause of leukemia whereas several chemical agents will cause blood changes in the nature of leukopenia without however, any further progression toward a lymphatic leukemia. Dr. Blankenhom suggested that we rely not only on proving the absence of Benzol exposure in this case but that we present as extensive a picture as possible of our 25 years experience with lacquers without incidence of leukemia, as shown by our relative divisional corporation and national lymphatic morbidity* Some of these figures 1 quoted to you the other day. We will advise you further when the cose progresses. AFL:ep CC : Mr. Ward 00122 y N13949 A. F. Lecklider, M. D. General Medical Director
