Dear Lederberg:

I have just learned that you are gcing to
give a number of talks at Yale between November 2 and 4.
I wonder if it would be possible for you to come here
either before or after vour talks there and talk at our
seminar. We will of course be glad to psy vour expenses
as far os they are not paid for by Yale and to have vou stay
here cver night or as long as you want to stay.

Cur Seminars are usually held on Thursday
afternoon at 4:15. I realize that vou cannot be here on
Thursday and I would like to leave it up to you whet day
or the week you would prefer to come here. Yleese let me know
whether vou would be willing to come since most of the people
here are anxious to heer about your latest results.

With best regards,
Yours sincerely,

tt Ewa,

E. W. Caspari
