Dear ir, Lederberg:

I have your request contained in your letter
of August 9th and as soon as my secretary returns around about
September first, we shall be glad to send you copies of whatever
reprints I have left that bear on the problem of bacterial repro-
duction and bacterial variability. It will not be as full a set
as I sent to Dr. Tatum inasmuch as our supply through the years
has gradually become exhausted. This pertains particularly to the
bound monograph dealing with the subject of sicrobic Heredity. I
am sorry about this because a person interested in the subject as
vitally as you are would find it convenient to have material right
by his elbow.

However, I know you will be able to use those
that I sent Dr. latum as long as you are with him, and you will have
the bibliography which is the next best thingy. I shall be very in-
terested in following the results of your very dranatic experiments
and I trust you will remember me when your own reprints come to hand.

Tell Dr. Vatum thet I shall be happy to take my
first opportunity to visit his new laboratory in Yale.

With kindest personal regards to both of you, I

Sincerely yours,

Halph , wellon, M. D.
