Dear Prof.. Lederberg,

You may perhaps remember that a few years ago I was:
writing to you about the work 1 was doing with Vibrio cholerae,.
Later on 1 was busy with other things and only recently
I have been able to resume this study. In @paper under
publication in the Bulletin of the World Health Organization

I have presented data frem which reveals close linkage between =

me
on

pur and ilva and the probable sequence of segen genetic s
factors.in V. cholerae, strain 162, A reprint of thishaper =

will be sent to you as soon as. copies are made available to me.

By the kind courtesy of the W.H.0, I have now been provided

with an opportunity to visit your country and in all probability

I expect to be in the State of California from iith Nov '64
onwards for a period of three weeks, 1 will be grateful if

you will kindly let me know whether 1 may visit your laboratory
sometime during this period to have the pleasure of meeting

you, Mrs Lederberg and other colleagues, Such a visit must
benefit me considerably. I prpose to spend sometime at

Berkeley and Los Amgeles as well during my stay in California.
Yours sincerely,
