Dear Dr. lederberg,

Thank you for your kindness in arranging for a
tour of the Rockefeller University facilities for
the Collegiate faculty. From our point of view,
the afternoon was a grand success. Those members
of the Collegiate faculty who attended were most
appreciative of the opportunity.

Once again, thank you very much.
