Dear Dr. Bartholomer,

A copy of your university's bulletin just came to hand, and I notdeed
that you have been teaching Bact 201, a course dn heredity and variation
in microorganiams.

We held a fairly successful seminar on microbial genetics in 1947-
48 when I first arrived here, but in order to reach the less specialized
students majoring in bacteriology, I have been planning a two-credit
lecture course to be offered this fall as Ag. Bact. ~ Genetios 107, under
the name of "Heredity in Mlcroorganisms". Judging from the statement
given in the bulletin, I would judge that our course will have about the
same objectives as yours. I am writing to inquire whether we night have
some benefit of your experience in handling this material. If you happen
to have prepared a lecture outline, I would appreciate seeing a copy,
and any comments that you might have, as to what the rough spots were,
or possibility of a textbook, and so on, would be very useful, and appreciated.

Concerning books, I had planned to suggest the 1946 Cold Spring
Harbor Symposium as background material. This might ba a little too
stiff, as well as being out of date. What would you think?

Yours siaceraly,

Joshua Lederberg,
Assistant Professor of Genetics.
