Dear Joshua:

Francis Ryan who has originally accepted the
chairmanship in the session on Microbial Genetics at the
International Congress of Microbiology, has just informed
us that he will be unable to come because of other
commitments. Would you have anything against taking the
chair at this session? The fact that you are moderator
of the symposium and a speaker within the session does
not matter at all. There will be another chairman,
probably Imshenetzki of the Soviet Union. Please let
me know whether this is agreable to you. If for any
reason it would not be, would you perhaps suggest some-—-
body else, preferably from the list of speakers 1 have
left with you. However, there is no reason why this would
be necessary; having studied the list with care, I do not
really think that there would be anybody to lead the
section with the same authority as you would.

Unless something went wrong, our contribution bart
to your travel expenses should have reached the North re
West Airlines Office in Madison some time ago. Would me
you mind checking with them and let me know if this is wore
the case?

With many greetings,
Yours as ever,

George Klein
