Dr. Jaakko Hinitikka [stamped, NOV 6 1980] Symposium in Finland I appreciate your thinking of me, and recalling our all too intermittent colleagueship at Stanford. Unfortunately the proposed meeting comes at a time when it is impossible. I am sorry to have to miss the opportunity of revisiting my own old friends in Helsinki, the Drs. Makela. Sincerely, Joshua Lederberg
