July 14, 1959 AIR MAIL L. E, Curtla, M.D. Standard 011 Company of California 225 Bush Street San Francisco 20, California Dear Doctor Curtiss I send herewith a further report of analytical results with such interpretative c o g e n t as seeiss pertinent. As you will note the urinary findings continue essentially without change. It Is now apparent that the additional exposure encountered by the men in the period of the Phase III observations has been insufficient to give rise to any increase in the excretory rate. There is no reason to suppose that anything of significance will develop during the remaining days of the test. ` The results of the investigation, including all of the analytical results on the urine and blood, will be re examined statistically and .in every other manner that is open to us, so as to yield their full complement of in formation, but the handwriting is on the wall now as to their pri mary meaning. . .r ! Sincerely yours, Robert A* Kehoe, M. D. RAKjss Enclosure m ii 3 y ir
