    DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Dr. Francis Crick Medical Research Council Unit for Molecular Biology Cavendish Laboratory Cambridge, England Dear Dr. Crick: Thank you very much for the manuscript which you sent to me. The work is beautiful and, needless to say, I read it with tremendous interest. I am enclosing two manuscripts of ours which are in press; one in Biochem. Biophys. Res. Comm., and the other in Proc. Nat. Acad. Sci. I expect to have another manuscript soon, and I will send it to you as soon as it is ready. Hopefully, it will contain some characteristics of the genetic code derivable from these and additional data. The work is going very rapidly and it is particularly excit ing at this stage. I hope to determine the coding ratio within a week or so. We have tried many approaches, including determin ation of molecular weight of phenylalanine, but technically the problem was more difficult than we expected. I am sorry that I was unable to visit Cambridge as I had planned last September. I returned to the laboratory about a week earlier than I had expected to, so I didn't have time for the trip to Cambridge. I am looking forward to seeing you here in Washington in February. I would like to extend an invitation to you to give a talk at the NIH. I hope that you will be able to accept this invitation. PUBLIC HEALTH SERVICE BETHESDA 14, MD. December 12, 1961 Sincerely.
