July 14, 1958 Dear Bruce: Further to my (not too enigmatic, I hope) cable. I am writing this letter a little prematurely, but have the tine _ just now and have to anticipate somwhat. At the instant, I'm waiting to complete the last stages of arrangements to move from Wisconsin to Stanford. This consideration was the min reason I was reluctant to accept your earlier invitation to indtrodude the SGi symposium next April, as I was very mech afraid I would be hopelessly enmeshed in problems connectéd with moving or deciding it. However, the air has been cleared lately, and whether we remain at Madison or move to Stanford we are strongly considering the possibility of spending April-May—June with Cavalli in Pavia. This not only would make the SGM do more convenient, but the fare would be a great help in financing the whole arrangement. I really can't go into all the ifs ands and buts by letter, but hope to talk this over with you at Royaumont, which is only 2 weeks hence. But if the opening hasn't already been filled (perhaps too mech to hope for) I wanted to ask you if you could keep it open until we could talk it over. The main eoncern is not so much the matter of moving (if we stay, ther's no problem; one of the things I have to find out is whether I can get some support from Stanford for the visit if we sign up there) but our obligation to Sneath, who will be visiting us nett year. I'd rather discuss this with him directly, and of course intend to at Stockholm, so I would ask you not to bring up the Pavia issue in referring to the SGM. Our itinerary for July-August is not altered from what you have, except we are leaving September 4 from London direct to San Francisco via the PAA - so-called 'polar route! flight 121 lvg.19:30 PM; we are booked for a flight arrvg. 7:30 Py from Glasgow (BEA 911) but this part of our itinerary is very tentative. But I'm sure I won't remember this again, so now's a good time to put it on paper. We had a splendid time with Luca, innumerable questions coming up and few being answered. It is clear that diploids can be formed with breaks at various places (in my earlier work my selection pattern was too rigid); but it is also clearer than ever that markers from the F~ parent can te eliminated as well as from the F’. We're sorry dane won't be joining you to the Continent; hope you can manage it to KEX¥ Royaumont; if not Shere we'll see you at Stockholm and certainly London. Yours,
