Wolfe, Chief AV io Environmental Sciences Branch Division of Biology and Medicine United States Atomic Energy Commission Washington 25, D. C. Dear John: A note on the molting of the coconut crab which has been submitted to Nature (London) is enclosed. As we learn more about this beast we should come to understand why their strontium-90 content is so much higher than that of other organisms. Everything seems to be in good order for the coming Rongelap trip. The schedule and requirements as originally submitted to USAEC, Honolulu, are enclosed. It looks as if the actual schedule will be very close to the same. “I still hope that you will decide to come out for part of the coming August trip. We should have some fairly exact dates for that trip when we return from this one. Best regards, A Edward E. Held Research Associate Professor EEH:sl Enclosures: (1) Molting Behavior of Birgus Latro (2) Proposed Biological Resurvey of Rongelap Atoll During March 1963
