I now spend a few weeks in the States and shall be next week in Chicago and Urbana. I should be very glad to visit you in
Madison if you have some hours free. The easier for me should be in the beginning of the next week. Could you give me your
answer c/o J? Novick, Chicago. I hope it will be possible for me to come to your lab without too much disturbance for you,
and I shall be very glad to meet you.
