Dear Drs. Sonneborn and Lederberg:

I guess I could wait until my next trip east; I am
however as impatient as my eight-year old in front of
the cookle jar.

So, I excuse myself for writing for the latest news
about your collaboration on the “Genetics of Microorganism,"
my excuse being that we should repeat we want to see it
with our imprint on it. Otherwise you might not realize
how great our interest is.

What conclusion did you two come to? Just a brief
line will suffice.

A good New Year to each of you and Mrs. Lederberg.
Sincerely yours,

W. H. Freeman
