Dear Dr. Lederberg:

A letter from Dr. Sonneborn indicates

that he would welcome your collaboration
on the Genetics of Microorganisms. Further-
more, he is apparently quite willing to
take up his pen again to prepare the def-
initive work he originally planned -- with
your able help. I need hardly add that
the collaboration has our enthusiastic
support, and we will be ready to make a
definite offer for the publication of the
book whenever the two of you are ready.

Will you please write Dr. Sonneborn concern~
ing the matter? I would appreciate being
kept informed of developments.

Best wishes,
JAB :mb FA Behnke
