Dear Dr. Kehoe: Ve nre called upon occasionally (perhaps once every tvfo or three months) to make analyses for lead in the blood and urine. Even if we were set up to make such analyses, because of theirinfrequent nature7 of s4-efo analyoos, I do not believe I wo; id .have much confidence in the reliability of the results. I have wondered therefore whether you might be interested in having re refer such analyses to you. If sc, would you cars to write re the approximate cost, your preference as to type and manner of collections, and the analytical methods you now employ.
