NEWMONT MINING CORPORATION 300 PARK AVENUE NEW YORK 22, N.Y. March 28, 1963 Dr* Robert A* Keh09 The Kettering Laboratory College of Medicine Eden Avenue Cincinnati 19, Ohio Dear Dr* Kehoe: One of our associated mining operations, Tsumeb Corporation Limited, located in South West Africa, has recently commissioned a new smelting plant. For the purpose of correlating the results of mine porphyrin tests and haemoglobin estimations to the degree of lead absorption, they require reliable blood analyses. Dr. Don Fowler of Lead Industries Association has suggested your laboratory as the best source for such analyses and we would be pleased to have you send us complete details of procedure and cost of this service. As the plant is in operation, the matter is becoming quite urgent and we would appreciate your early advice and instruc tions. Thank you. Yours very truly. HWV/mra H. W. VOLKMAN KE 0018308
