I was very pleased to learn that you have won the Nobel Prize. I wish you good luck in your future life and further big successes
in the field you made your basic discoveries.
I hoped to meet you here in August and was very sorry that you could not attend the Internatl. Genetic Congress. I wanted
to discuss with you several questions, as I am supposed to do some genetic work on mycobacteria. This year, as you know,
I've been working on the cytology of atypical forms of M. tuberculosis (BCG) and I am now looking forward to publish a
detailed account of the work I've done, so far. I am not very happy, as you can imagine, to work with mycobacteria in
view of the difficulties one has to face when investigating cytological or genetic aspects of this type of microorganism.
I often wish I could work again with those kind[?] organisms of the enteric group, which are most suitable subjects of such
research. The hospital, with which I am associated since I came to Canada, is, however, a tb hospital and thus mainly interested
in the tb bacillus.
Just for fun, I have been playing around with the idea to ask from you those cultures of E. coli which you described as highly
interfertile and which show conjugal pairing. It would very well fit into my plans to look for a method for demonstrating
in living cells the process of conjugation. Later, however, I decided

to wait and let ripen the whole question. For the moment being I'd like to ask you two other things. First, how did
you obtain DAP, since to our order [ . . . ] has replied that they dont [sic] produce it? On the other hand I'd highly
appreciate to obtain a streptomycin-dependent strain of E. coli. I hope you dont [sic] mind for bothering you with these
things. Thank you in advance and congratulate you once again
