July 18 Dear Dr. Lederberg, I am planning to arrive in Madison on the afternoon of Aug 1, and will be grateful if you can make an inexpensive room reservation for me, probably at your Union. I would like to stay several days, and if you are interested, we might start work on meningococci together -- they are not so fussy as some think. But that is the main subject I want your advice on. Yours, Gordon Allen
