Dear Dr. Lederberg!

Thank you very much for the
reprints kindly sent to me. I was
especially interested in the paper
on phase-variation in Salmonella.

When you are coming ta Europe
together with your wife and should
have the time for a visit of Copen-

hagen, you would be very wellconme.

With kindest regards
Yours sincerely,
