Dear Dr. Bradley:

I have just seen your article on "Reconstruction of Protkin and Nucleic

Acid Sequences. I, Systematics and Computer Program which appeared in

the Ocbober, 1964 issue of Biopolymers, and would like very much to have
a reprint of it, and any subsequent reports you make on this subject.

I would be interested to see any other articles related thereto that you
could send, or perhaps send reference information on.

Sincerely yours,

Joshua Lederberg
Professor of Genetics
