July 6, 1951.

Dear Dr. Deswrec:

I enclose herewith the odde-and-ends to my ms. for the
Cold Spring Harbor 1951 Sympeeium . I hope that this unavoidable delay
has not thrown you off schedule for publication. Please let me
know if any of the instructions are unclear, and I will hasten
to clarify ting.

Mra, Lederberg and I found the meetings very stimulating, and
enjoyed the opportunity to attend thea.

We have a considerable number of 35am. anapkhots of participants
at the symposium. If you are lacking suitable photographs for the volume,
let me know whom you need, ani I will try to send an enlargement if

we can

Stacerély,

ho

Joshua Lederberg
