Dear Dr. Fredericq:

Thank you for your good letter, and for sending your cultures, which
I shall look forward to receiving. Under separate cover, I am sending you
strains 58-161 and %-1177, as described in the enclosed circular. These cultures
are available for further distribution by you at will, but I would appreciate
a notification of any other workers who will receive thea.

Yours sincerely,

Joulma Lederberg,
