' Dear Professor Lederberg,

Thank you for your kind letter of February 20. It is
of course always a great pleasure to understand that old things
are being used also to-day, and I am only pleased to be in any
way of value for you. My Librarian did not like taking it out
of one of our last yearbooks, but gave up her resistance.

With kindest regards,

yours sincerely
