Robert A. Kehoe, M.D. University of Cincinnati The Kettering Laboratory College of Medicine--Eden Avenue Cincinnati 19, Ohio Dear Dr. Kehoe: Thank you very much for the kind remarks you and Mr. Cholak make about the recently revised "Methods for Determining Lead in Air and Biological Materials." With the careful care the revision has had, it would be extremely surprising if it were not an excellent report. lour order for 250 copies is in the works now. I am happy to tell you that we will be able to give you a special price of $ .90 per copy on this quantity. You will, of course, receive a bill in the normal course of events for this. We have several hundred copies of the report, "Occupational Lead Abaorptioft and Lead Poisoning". I;have not bothered to get an exact inventory on this because the report is moving so slowly, that, based on the experiences of the past three or four years, it would be safe to say that we have enough to keep us going for several more years. It nowilooks as if the report will not be reprinted because of our stocks being exhausted but rather because it has become out of date to such an extent that the current edition should no longer be sold. Of course it would be necessary to consider the financial matters involved in a revision in view of the rather poor sales. The Committee on Research and Standards asked the Industrial Hygiene Section for an opinion as to the need for revising the report back two or three years ago. At that time the Section was of the opinion that a revision was not necessary. Sincerely, Engineering Associate N20405 89CSIQ0 J3U
