Dear Dr. Plough:

Thank you for youb letter of the 31st. Esther and I are looking forward
to our first visit to the Amherst campus.

You were quite right about the status of our manuacript-- we shall have
to work this up over the summer after the meeting. Our plan is for me to
speak from rough notes, as I did at Oak Ridge, but more briefly.

The best I can tell you of the probable content of our paper is that it
will cover much the same ground as my talk last year at Oak Ridge and my ar
ticle in Physiological Reviews (Océ. 1952). There will not be mich reference
to unpublished results except perhape on traneduction of the Lp-Gal complex
in E. coli, which was already mentioned last year and in a Genetics abstr.,
393984.

Yours sincerely,
_ Joshua Lederberg
Professor of Genetics
