Cincinnati College of Medicine Cincinnati, Ohio Dear Dr. Kehoe: Mybrain was so edematous from a nasty head cold that I fear I was a poor hostess indeed during your recent trip to Boston. I must say I was really very much touched to have you take the traibls tocome out V^HThe Statlr, have your taxi wait, and then go back after the rug ged trip you had had. I do hope you will come to Boston again and find me in better health because I would like very much to entertain you socially and to showyou what kind of work we are trying to do here at M. I. T. and at the hospital. I have a question I wanted to ask you and since you are so busy, you can perhaps tell me the answer when I come to Cincinnati. I want to knowhowlong lead continues to be excreted after exposure ceases. I have read some of your earlier articles on this and have the im pression that within a reasonable tim, depending on the character of the exposure, one may expect to find less and less lead in the urine. I have had several very puzzling cases with excretions in the urine to .20 milligrams per liter as long as a year and a year and a half after any detectable exposure beyond what all of us re ceive. Is it true that some of the lead is deposited in the cortex of the bone and so never does get excreted? I think some of your studies on autopsied cases suggest that this is probably not true. This is a big subject, and we can talk about it later. Sincerely yours, M. D H:g N5965
