When I returned from my multifarious wanderings to the West Coast, about the 1st of November, I stayed in Pacific Grove for
a couple of weeks in order to write up the talk I had given at Princeton. Mail sent to the Calif. Institute was kept here
for me. As a result I did not get your letter of Nov. 4 until about the 15th-20th, when I finally returned to Pasadena.
Then I realized that I had shamefully forgotten to look over my card index files for references on variation of a heritable
nature -- as I had promised to do when I last saw you in New Haven. Two ways were open to me: write home and have that part
of the files dealing with variability sent down to me here -- or wait till I would be in Carmel next. For various reasons
I took the latter course, and during my last visit to Carmel, a week ago, I made the requisite notes for replying more or
less adequately to your letter. When I returned to Pasadena just a week ago, there was so much work to do that I felt compelled
to postpone for another week the sorting-out of references etc. which I had collected. Now is my chance, and here follow some
titles which I believe you ought to consider:

rod. J. Bact. 38. 641. 1939.

There [?] you can also find a complete bibliography of his earlier writings.
I do not mean to imply that all these articles and books should be part of the bibliography of your paper. But I do insist
that you should familiarize yourself with these publications, so that you will know what others have thought and done about
problems which are related to sexual reproduction in bacteria.
There's one more paper for which I could not find a card. It deals with supposed conjugation of spirilla and of Chromatium
in cultures of these organisms; Was written by Pothoff, and published around 1926-27 in Centralbl. f. Bakteriol., probably
in the II. Abt.

I hope that this may still be of use to you; even if the paper (or thesis) has already been completed, I believe that, in
order to gain some more perspective, you would do well to look at these papers.
The results of the simultaneous inoculation of three types (A minus B minus C plus; A minus B plus C minus; A plus B minus
C minus) was very interesting. However, you failed to write that A plus B plus C minus, A plus B minus C plus, and A minus
B plus C plus had been recovered from the culture, merely stating that A plus B plus C plus was not found. Yet, the former
should form an equally important part of the argument.
Best wishes and regards, also to the other friends at New Haven,
