Memo from 10: JOSHUA LEDERBERG DEC 15 1970 Mr. Mark Talisman Insertion into Congr. Rec. Dear Mr. Talisman-- I am sure this does not deserve your highest priority; but I have had a number of inquiries about this article, and it would greatly re- lieve my own embarrassment (and perhaps help to clarify some others' thinking) if you could indeed help to get this on the record. Yours sincerely, _ PROFESSOR JOSHUA LEDERBERG Xx Department of Genetics > School of Mcdicine ) Stanford University Stanford, California 94305
