July 22, 1959 AIR MAIL L.E, Curtis, M.D. Standard Oil Company of California 225 Bush Street San Francisco 20, California Dear Doctor Curtis : I am sending herewith, as in other instances, the latest series of analytical resulte. These I believe will be self-explanatory, and m y comment on them, while relevant, is not of earth-shaking Importance. I have taken a look at the results which Dr. Gerlach <has sent me, and have compared them with our own results (not yet completed) on the samples obtained during Phase III. You '"will note that there is a significant difference be tween the two sets of results. This, of course bears out my statement that no two laboratories obtain precisely the same results, and illustrates my point with reference to the necessity of having strictly comparable data in a situation of this sort. . v . . . With best regards. Cordially yours, RAK:ss Enclosures Robert A. Kehoe, M.D. 0004000
