January 14, 1957 Dr. J. J. Weigle Caltech Pasadena 4, Calif. ; Dear Dr. Weigle: o We have your two letters from Puert@ Vallerta, and the copy to Morse / from Pasadena. ie had waited to reply until you had returned to Pasadena / thinking you went to Mexico for qiiet and seclusion. The Gal Lp. ‘wl you ested were, h r, sént several days ago and should be In yo ands very soon. Wa did not realize you seriously wanted us to commnt on the advisability of your publishing the note: it appeared to us that this was already com- pleted and submitted. This is so much a matter of personal temperament that we hesitate to forward our om views, and certainly would aot insist on them. However, as you now state that you do intend to proceed with the analysis discussed in our correspondence, we do wonder if this note is not somewhat premature. In similar circumstances —-e.g., the behavior of prophage markers in transduction, and the unstable Lpt phenotypes,—— we have felt that the story should be completed before it waa published. “ But this is not a sort of question that can be profitably discussed in e written correspomlence. Fortunately, there is still some personal liberty in sclence, and not a rigid code to which we mist conform. VIG I FOR As wealso brought up earlier, Dr. Morse is most immediately interested in the problem of growth of HFT lambda. Although we are, of course, deeply concerned, he has to be consulted first with regard to any 'division of laubor' in further studies. i to be completed. An unpublished \summary of our wor “being drafted now as a ‘progress repart'-for research \_ gronts, and you .and Kellenbe j wili receive cupiss when this is ready. Yours sineerely, CC: MLM Joshua and Uether MM. Lederberg
