Istgenetica - Pavia Tel. 23.029 ; 29.038 - Indirizzo telegrafico ; 8th June 1960 Professor Joshua Lederberg, Department of Genetics, UNIVERSITA DI PAVIA Medical Center, , VIA SANT’ EPIFANIO, 14 Palo Alto, PAVIA California. Dear Joshua, The book on fluorine that we have been waiting for is Simon's (Fluorine Chemistry). It was ordered about two months ago and is due to arrive any day. If you see any books on the subject or related ones that you think we should have, please order them for us, if this is not too inconvenient, and.shall reimburse you. Wwe I should obtain the visa next week,{I shall write as soon as I know the exact date of our arrival. I have at present an alternative booking: either SF through NY, arrival 12.25 pm on July 3rd (TWA 45), or SF through Mexico City arrival 17.20 on liionday July 4th (Western). As I hope my lectures will be on Tuesdays, Wednesdays, Thursdays; nothing much should be lost by cu: wy arriving on lionday, and it would give us a chance to spend some time at Cuba - Merida - Mexico City, almost without extra expense, I will therefore, if possible, keep to the second schedule. Thank you for the notice of the apartment which seems quite suitable. As far as cars go, we have had some change of mind; Alba will probably prefer a bike, so I will look for one car ~ unless you have already found two. All best wishes, and I am looking forward to seeing you both again, Yours, hater
