Dear Dr. Lederberg,

You may have seen from my recent commnication in the Journal
of General Microbiology(19,71, 1958) that I am engaged in the study of
genetic recombination in Vibrio cholerae. ‘This is based on your work
with B, coli and Salmonella.

You will find enclosed herewith some recent observations in
connection with this study which, 1 expect, may soon be published.
I am sure you will be interested ina study of this kind and hope it
will not be a bother to you to examine it and give me the benefit of

your valuable advice and critician. I will be most grateful indeed,

If you are interested in any of the strains of V,. cholerae used
in these studies, I will be only too happy to furnish then to you,

With best wishes,

Yours sincerely,
<ar\
