Dear Dr. Jenkina:

I con't have to tell you how much Esther and I heve enjoyed our
visit to California. Your department's further interest in me was the
dieing on what was already a very delicious cake.

I could rot think of any more fundemental questions than we had already
gona over. Of course there sre nany details to be gone into if the baste
mitters can ce handled smocthiy through your aduinistration and faculty
committees.

Under separate covar, I am sending some reprints that may interest you,
and I would be grateful for an exchange. The enclosure may al30 be of some
use to you, or at least for your fires.

with beet wishes fcr the new year,

Yours sincerely,
