Dear Dr. Lederberg,

Thank you for your very helpful letter
of the 13th. I have written to Professor Keit& to-day
outlining my thesis studies. If I am fortunate enough to
come to Madison I shall be delighted to take up your kind
invitation to seminars and discussions.

I am arranging for Professor Keit& to
receive letters of reference from Dr. Lewis and Professor
C.T. Ingold, under whom I studied at College, and have
asked them to write to you too,

With regard to the samuts, I do know
David Perkins’ work on Ue pares. I have corresponded
with him several times. My intention was to work with

the anther smuts - of Melandrium album and M, rubrum
(U. violacea).. I have the two Melandriums and their

hybrid but have not-yet worked with the smuts although I
have material. of both types.

. . Tr shall certainly get in touch with
Dr. Paul Allen and am glad you mentioned him.

Thank you once moré,

Yours sincerely,

ou
