Dear Dr. Myrianthopoulos:

This is just to let you know that the two tapes that I took back home with
me appear to be in very good shape. We have read and made a back-up copy of
them. We are just in the process of loading them onto our disk file for
more convenient access from our terminals, and will soon go through an exer-
cise to compact them to the particular data we would be most interested in
for the first pass at computation.

8 Sincerely yours,

Joshua Lederberg
Professor of Genetics

P.S. I enclose a copy of e summary of the file specification information
that Mrs. Hwang prepared. This text is now also stored on the file, and
we can readily clean up some of the typographical errors that crept in.

Before we do any very extensive runs, and after we have done a few test
trials, I will be in touch with you to be sure we make the most out of
every pass. It looks promising!
