Dear Harry:

Along with some reprints enclosed herewith, I thought you might wish
to see an ms. (prepenultimte draft) of a paper bearing on the mechanism
cf drug-resistance. The ms. has been accepted for publication in J. Bact. ,
but won't be out for some months. If convenient to you, I should like to
have it back in 2 week or two,

Sincer alg,

Joshua Lederberg
