Dear Dr. Cord:

Z would appreciate the favor very mich if I could receive the receht and
current publications from your laboratory on the action of polysaccharide
synthesizing and degrading enzymes. We are very such interested in these
questions from the point of view of the determination of macromolecular speci-
ticity, and for biochenical-genetic studies on these processes in bacteria
(Cf. Doudoroff et al., JEC, 179:921, June 1949).

Yours sincerely,

Joshua Lederberg
Assistant Profeasor of Genetica
