Dear Josh, Thanks very much for your letter which came as a very pleasant surprise. I am of course thrilled by the idea of seeing you and Esther again in your new surroun- dings. My plans were completed and my itinerary was ~- after the fest models - sent around to the people I was going to visit. As all these visits are in the vicinity of New York (in a rather wide sense, i.e. Atlanta, Washington and New York itself) I feel that the best thing to do will be to go to Stanford.on the 30°" of September after the visits already planned. I have no timetables at hand right now but I feel that quite a number of flights from New York to S. Francisco are available, and further that departure at noon from New York will bring one to S. Francisco the same evening. I have ordered a around trip ticket Copenhagen-New York- San Francisco ~ New York - Copenhagen and according to the available information the difference in price between the original around trip ticket Copenhagen ~ New York and the new one Copenhagen - San Francisco will be 232 &. I am very happy about this extension of my trip and am really looking foreward to seeing you both. Greetings from Ida. Yours, ? nt Frits Orskov Statens Seruminstitut Copenhagen Denmark. Arr.
