Dear Mord! and Seymour:

Of course, I have no objection to your using the paper mentioned
in the attached copy of your letter of June 19. However, the copyright
is owned by the publisher, William: add Wilkins, and you will have to
get theiy formal approval. They have been cuite obliging in the past,
and I imagine they will accept my approval on behalf of both Tatum and
myself. Ed is, unfortunately, practically inaccessible on a European
trip, but I do not think he could raise the least objection,

Precisely what do you intend to do? Are you reprinting a series of
papers in their entirety, or are you making excerpts? You might be interested
in what may be akin to your project, deserihed in the attached circular.
You will note that a different paper was used to exemplify recombination
in bacteria. Possibly you felt the Genetics, 1947, article was tco difficult
for your intended audience; 1t certainly was intentionally written at a
different plane from the preceding Jour. Bact. article. The essential
design of the experiments was presented rather more briefly (and earlier}
in Nature and at the Cold Spring Harbor Symposium (1946) [References in
attached list]. The historical account in the enclosed reprint may also be
of som interest to you.

Best wishes, Will we see you at Woods Hole (in August) ?

Yours sincerely,
