t July 22, 1937 Dr* W* H* Whitman Norfolk and western Railroad Company Roanoke, Virginia Dear Doctor Whitman* Proa what you have told me in your letters concerning cases of illness in men engaged in osy-aeetylene cutting operations, I am in no position to say that you were dealing with lead poisoning* However, that lead poisoning of the most severe types may occur from the cutting or burning of metal coated with lead paints is so well known in certain trades, especially in bridge building and ship breaking, as to require no proof from me* The chemical department of your company is taking a very vulnerable position in constructing their very original hypothesis concerning the impossibility of the inhalation of lead under these conditions* Indeed, no hypothesis is required here at all, since the facts are well known* However, just a,little discussion of the theoretical issues at stake may be justified* You quote some technical person as stating that, "To be inhaled into the system through the respiratory organs it would be necessary for the lead to be converted into a gaseous state, and we have never known of lead being converted into such a form."
