Dear Dr. Lederberg:

Dr. Sernard Davis has written to me about your generous
offer to let me spend some time in your laboratory late this
summer, to get advice and experience preparatory to studying
recombination of virulence factors in (2) meningococcus.

My chief concern at the present is the choice of the
organism, and if seeing you would help me with that decision
I would want to see you before I start my work, which was to
be early in August. Since I have only 10 months in which to
complete my experimental work before returning to medical
school, I would rather not postpone the work until September.

I shall be in Columbus until July 31, and the most con-
venient time for me to go to Madison would be immediately
after that. Will you please le t me know if you will be in
MMdison on August 1, and how long you would want to stay
around? I would consider the trip worthwhile if I could spend
& Single daywith you,

Sincerely yours,

Ldn Clb
