Dear Doctor Lederberg;

I have obtained cermission from your pub-
lishet to use your excellent article "Sex in Bacteria"
taken from the book Sex in Microorganisms in my
genetics course at Goucher this year. Instead of using
a text book, I am having a series of original articles
mimeographed. In case you have a reprint of the
articie I should very mich like to obtain a cépy. Also,
allow me to thank you for the reprnts you have sent me
in the past and also to say how very much I admire your
beautiful studies and the clear manner in which you
write them up for publication.

Sincerely yours,
