ISTITUTO DI GENETICA November 18, 1958. UNIVERSITA DI PAVIA = Prof. J. Lederberg PAVIA Department of Genetics VIA SANT’ EPIFANIO, 14 - TEL, 23,029 University of Wisconsin MADISON 6 Dear Joshua, I have sent you a tape a few days ago, but in order to avoid further delays in mailing it, I decided not to go through it again before sending it and there may be a possi- bility, however small, that it is blank or not very clear in some parts. Therefore, I want to confirm a few of the most urgent points so as not to leave any doubts on them. It will be alright for you to carry out your programme as outlined in your letter of November 7th regarding your flight to Milan on December 14 to 17. It will be best to go together to the Riviera Ligure, but we need not make detailed plans now. As regards your coming here next year, we thou ght that, as you will leave from California rather than Wisconsin, we should allot g. 2,000 for the return trip for you and Esther + plus #. 500 a month for your stay here, to you or Esther. If you think you can get any portio of the fare from other sources, so much the better, put it is very likely that Montalenté will only want to pay your fare from Milan to Naples. I will of course promise that no public appearances will take place and will be looking forward to seeing you again. Yours, one. + ghhactuy L.L. Cavalli-Sforza 4 . LLCS/at.
