Kehoe Kettering LaboratoryUniversity of Cincinnati College of Medicine Cincinnati, Ohio Dear Bob: I was intrigued by your discussion with me last Friday on the subject of lead intake on various sources. After you left, I tried to summarize your statements in the table which is enclosed. Is this substantially correct? I am enclosing an extra copy on which you might scribble corrections, if any. I think this would make an interesting paragraph in an appropriate section of my book on air pollution. Would it be all right to include it ascribing credit to Kehoe, Private Communication?
