3rd July 1956
Dear Josh,
The plan is to go to Milwaukee on N.W. 311 and then take flight NW 431 to Madison--more or less as planned--arriving 8:44 pm Friday evening.  I have not yet had my booking confirmed, but if you don't hear from me further I shall be arriving on that flight.
It would be nice to see the Biochemists, too, if we could fit that in, especially Heidelberger, who has a result which might bear on the coding problem.
Greatly looking forward to it,
Yours ever,
Francis
