UNIVERSITY COLLEGE LONDON DEPARTMENT OF ZOOLOGY Telephone : EUSton 7050 GOWER STREET WCI Professor P CMa) . 23rd January, 1961. x A Dear Joshua, ge N Many thanks for sending me the copy of your letter to Milan HaSek - I hope he acts on your suggestion. I myself do not quite see the point of a conference on tolerance, and I am really only going myself in order to humour Milan. I will mention Nossalts name to Wolstenholme of Ciba, but the trouble is that he is very tough-minded about restricting the numbers to 30, and a whole lot of people are already clamouring to get in. However, I would much rather have Nossal than anyone else; but if you hear nothing,I am afraid it means that the Symposium is completely full up. Yours ever, Dr. Joshua Lederberg, hee Department of Genetics, Stanford University Medical Center, Palo Alto, California, Gee U.sAe
