Dear Mr. Tomasz;

I have just heard from Dr. Gyorffy that he expects to attend the
Ciba Symposium, March 25-28, if you have not already heard this yourself.

I wiil of course be happy to give him your own good news. However, Br.
B. D. Yavis » Professor of Pharmcology at N.Y. University will also be atten-
ding, and is closer to you as a possible intermediary. He is also attending
the meeting. I embark myself March 6.

Yours sincerely,
é

Joshua’ Lederberg i
Professor of Genstics.
