UNIVERSITY OF CALIFORNIA DEPARTMENT OF CHEMISTRY BERKELEY 4, CALIFORNIA October 7, 1960 Professor Joshua Lederberg Department of Genetics Stanford University Stanford, California Dear dosh: Many thanks for your note on the flying czmera. I somehow had missed that squib. I probably was away when that particular issue came across my desk. I have started the machinery to try to find out about the spectro- meter that flew as well as the results that may have been forth- coming. This I have done both through Washington, London and Ox- ford. It also turns out that a similar operation is underway through the Weather Bureau and we are now trying to discover just what has oceurred there. Greetings and very truly yours, 4 / Melvin Calvin MC gmt
