Dear Paul~
Sorry not to have answered sooner, but I'm thoroughly tied up trying
to get away to CSH. We're sorry, of course, not to have you with us next

year, but I'm sure you would not have regreteed either alternative decision.
The best of luck to you.

Perhaps if we can get together in Minneapolis this September, we can
discuss the possibilities of other means of getting off to a good start in
microbial work. Please give our best to Elisabeth and Carl.

Yours sincerely,

Joshua Lederberg
