ISTITUTO SIEROTERAPICO MILANESE “SERAFINO BELFANTI,, Ente Morale aggregato alla Universita di Milano Via Darwin, 20 - MILANO TELEFONO 35.74.41 (cinque linee) Telegr.: SIEROTERAPICO - Milano Oct.11,1957 Your letter of Sept.30 announces a shater visit than anticipated,but at least a defini= te one,and we are all extremely pleased about it. In view of the time available it is perhaps wiser to leave Rome for another timesalso ,I have had no clear answer from Chain yet,so I will assume that you come straight to Milan. Thursday November 21 hs a good date for me;if you have to alter it,try to keep a weekend included in the time of your visit. Please let me have a title for your Milan lecture at least ten days before you will be here.&s I wrote you already the lecture should be fairl: elementary,in the sense that theaudience is likely to be a mixed one,of non bacterial geneticis sts and non genetic bacteriologists,plus a few hybr= ids, I am sure you are familiar with this story. You do not need to send titles for one (or two) semir mars in Pavia. You can certainly get from Milan and Pavia $ 150 (total) ;plus I hope 2R@ another 50, Your hotel in Milan will cost about $ 9 perday with bath. Dear Joshua, A number of difficulties concerning my future decisions shoudd be solved by the time you come herefThere are lots of things boiling at the moment; 1 hope they will cool down soon. I am enclosing a preview of the part of the family which you do not yet know.I had pro= mised to send it long time ago.Sorry for the delay. We are all looking forward to having Yours hue a you here,
