Dear hayss,

The Lederbergs and I have agreed to write join-
tly «bout our observations on tue transmission of Fe, the fertia
lity factor, and since some of our observations, at least tose
on genetic infection,are so close to yours, we thought that it
might be reasonable to publish auch a paper on the Journal of
General Microbiology , possibly in the same issue in which your
paper on the same subject wil: appear - I hope I understood cor~-
reetly when you said you would send a paper to this journal, I
am nyself a member of the Tociety of General Microbiology,and
I hope we shail huve the paper accepted. If you think tis suits
you,we may perhans send botn a word to the editors about it. TI
expect our paper may be ready by tne end of this month.

48 you know,both Lederberg and I cannot agree to
the idea cf a “self-reproducing gamete" ,which seems to obscure
rather tnan to enlighten the picture,and it may be worth expres
sigg our views on this in the paper. I eam telling you this,also
on agrfement with Lederberg, because you m gnt like to take this
opportunity to clarify your own views on the matter on the JGM
paper, I have tried to express to you my ideas in London,but the
time hus been unfortunately short, and the discussion took place
mosil; aftcr a good meal . However, should you like to have fure
ther exchange of ideas and comzents on the subject, T should be
quite glad of dotng this by mail,

I have not yet tried the sample o* DNA-ase which
you kindly sent me,but nope to do so next week,

with best regards to iirs. Hayes,

Yours sincerely

e/ to Lederbderg.
