March 31, 1955

Dear Joe:

Just after sending off a couple of records, I remembered an article
by Routden and Finlay in Bact. Revs. (June 1952). The review goes into
many aspects that I had touched on before, ani by and large in an intel-
digent way. Is this article the best clue to current practice? They
seen to be sensitive to som of the same angles you have brought up; it
is harder to tell how far they are put inte practice. The one arena where
your competitors are probably weakest is in genetics, and even there a
purely empirical appreech, at the present state of the art, may be alma. st
as productive as a more sophisticated one.

If you know of any other literature along these lines that would enlarge
my own background, so let me know.

Yours sincerely,

Joshua Lederberg
