Dear Dr, Lederberg:

I wish to thank you for the reprints and for the abstracts of
your current work. I listened to the presentation of Zinder but
was quite disappointed that you did not come to the meeting. It is
wonderful to see the development of your work from the neurospora
to the K-12 to the recent observations. I see from your paper pre-
sented at Cold Spring Harbor that you were influenced for a while
by Klieneberger's ideas,. I am enclosing an electron micrograph
Which I recently made of the L form of Proteus, It is very inter-
esting that life continues in such small forms even if we do not
know the significance of these forms, If the smallest form can
reconstruct the bacteria, which we do not know, they could not
carry toomany FA particles, I will repeat my former efforts to see
whether L forms obtained from different strains can recombine and construct
bacteria different from their parents. It is difficult to believe that
these forms have no biological significance,

I hope that we will be able to discuss these problems personally
in the near future.

With kind regards,

Sincerely yours,
