Dear |Bob: I deliberately didn* t answer your letter of July 3d for I fig ured you were probably on your holiday. In the meantime I had hoped that some of my colleagues would complete some basic studies regarding your dihydrothiotic acid. Our studies on the possible usefulness of this compound in lead intoxication are not quite com plete}, but I will get in touch with you when -they are. j S * 1.* - -7--- y f i1 / I share your enthusiasm for a program of sound industrial hygiene; I doubt seriously, however, if the rank-and-file painter is ever going to subject himself to the precuations that may be necessary to prevent his getting lead poisoning by inhalation. These are the people who, I thought, might profit by some kind of a prophylactic which could be taken by mouth in case we prove the chelating of thioetic acid. It was farthest from my-mind to do anything from this point to tend to encourage sound industrial hygiene, but you have been so instrumental in helping to erect it in this country and as soon as these data are completed, I will get in touch with you. Sincerely yours, RESEARCH DIVISION, American Cyanamid Company JMRsST Jv"4. Ruegsegger, M. D, Clinical Research Section N 6268
