Carbon monoxide is mentioned but I cannot see that anyone has made a diagnosis of lead poisoning in this case, I as referring the correspondence to Dr, Kehoe of the University of Cincinnati and sill ask him to advise you on the subject, but, at the moment, I see no reason to suppose that lead has played any part in the systems of the man in question.

I trust that the future years will continue the Upward trend for lead.

I am venturing to write to you because of your association with the Kettering Laboratory Abstracts to discover whether you can help us in locating references to comparable work on organic lead, specifically tetramethyl- and tetraethyl lead and the corresponding trialkyl-lead salts.

Thi. 3 Is no surprise to ns, and it will not surprise you, but It is of some con sequence to recognize that, following the absorption of significant quantities of tetraethyl lead from any source, or over any length of time, the concentration of lead in the blood undergoes little or no change, while the urinary lead concentration goes to high levels which vary with the severity of the exposure.

The lead was weighed into PVC bags and sealed.
