Dear Josh:

Many thanks for reading the chapter on "Recorbination" and for your
interesting comments, including those contained in the nortion of the US
which you sent me, I am glad that you are also willing to take a look
at the chapter that conteins references to the transduction work. Enclosed
I am sending you the draft of that chavter and I shall appreciate all
critical comrents, I am fully aware that an over-all title for this
section, such ac “infective heredity" or "infective transmission" may be
advisable, but I am still somewhat hesitant to use these particular terns,
because even fertilization could be regerded as infective heredity, Your
recent use cf transduction as the major heading, makinc- trensformation
only a sub-classification, may be the arnronriate ster. I have tesiteted
following your example merely from a historical stand-pcint, which, of
‘course, May be a wrong stand-point,

T hore iladison is a little cooler this July than Frederick, Them
kind of weather we are havine here is certainly not favorable for any
