Dear Dr. Lederberg:

As you certainly know, Dr. Silvio Varon came in .the late
fall to St. louis to work with us. I have enjoyed my association
with him and I came to deeply appreciate his sharp grasp of bio-
logical problems and his original thinking about possible new
approaches to the study of the nerve growth factor.

A position of Associate Professor has been offered to him
by Washington University and I had hoped to make my association
with him a permanent one. However, as Silvio himself will tell you,
the limited facilities in our laboratories in St. Louis will not
permit us, in the next two years, to carry on a thoroughly
biochemical study of the nerve growth factor.

I will be pleased if Silvio would extend our work on this
factor in your laboratory since my main interest is to see this
problem developed as vigorously as possible. Of course it will be
your and Silvio's decision if and to what extent this fits in your

plans.
Cordially yours,
Jy tk. Lev: - -) we crAe
