March 30, 1967 Dr. Orio Ciferri Tetituto di Genetica Via Sant' Epifanio, 14 Pavia, Italy Dear Orio: I have just heard from Luca, following his delayed return, and while I was delighted to hear what kind of adventure he was able to have - of course depressed about the tragedy of Roghi - he does tell me that it would be better for me to defer my visit for a little while. So I think you will be able to collect on a bet, although I can pretend that it was not within ny own control. Luca also tells me that the Pavia-Stanford arrangement is Okay again. I hope this means that there is an officéal approval on the Italian aide, and I am going to go right ahead as fast as possible with getting some necessary funds from the NSF. I hope this will inspire you, among others, to come back here and I would we glad to hear of any tangible plans that you micht have for that. Sergio has been movinggalong in a very nice way, as I am sure he has written you, but it would be very nice to have you back here. I am very grateful for the trouble you have already taken about connecting my column and Tl Giorno, and I am perfectly content with any of the arrange- ments that you suggest or any others that your good judgment would support. Is there anything more that I should do, or will it be possible for the editors now to communicate directly with the Washington Post? Your remark about the collapse of the arrangements for the Stanford—Pavia axis was very disturbing, but thep Luca was wettten me that it is okay, I hope his is the later statement. I will ask him to keep you in close touch with the information that I exchange with him from now on. I have a fond recollection of you and Paula whenever I use one of the very brilliant gifts that you arranged for her to send me. I have frequent occa-~ sion to be quite grateful for it. Cordially, Joshua Lederberg Professor of Genetics (Yy¥4d/9
