Dear Bill:

Ed Adelberg called my attention to the confusion that may arise
owing to the difference in terminology used in the abstracts of which
i am enclosing Thermo-Fax copies. It will not be fatal if F' in
Hirota's article Is written so that It can be distinguished from F .
If they are confused, there wil! be an out and out contradiction which
carnot be but very confusing in a field which is already sufficiently
difficult. For that reason, | would urgently request that you add the
enclosed note to Hlrota's abstract. This might not have happened
except that the notes were sent in just prior to our departure for
Europe, a trip from which we have just recently returned. We are in
close touch with Adelberg and will take care that this kind of difficulty
does not recur.

With best regards,

Joshua Lederberg
Professor of Genetics
