Dear Dr. Hayes,

I am sending you herewith the paper by Cavalli and
Lederberg. This, we feel, is a work of fundamental importance
though, of course, opinions as to interpretation will differ.
The trouble is that the paper is presented (avart from the
English which obviously needs corrections), in such a non-
systematic way that reading is very difficult. There is far

too much non-essential details and references to other problems,
ete.

Further, it is on the basis of Table 2 that the reader
must weigh the claim that the F+ parent contributes less than
the F- parent, but this table is virtually incomprehensible and
can only be understood by repeated references to the text.

The trouble is this paper not only needs rewriting, it
needs replanning. I shall rely on you to do as mich as you
possibly can and take the paper out with you to dise iss with
Cavalli. Let me have it back as near September 17th as you
possibly can in a form more or less ready for the press. I
shall then do the final editing and will war the Cambridge
University Press that this paper will arive late, as I want

to get this paper and your paper into the next number side by
side.

Yours sincerely,

A.F.B. Standfast (Signed)
