Dear George:

Thank you for your note of the 20th. 1! look forward to hearing
more from you.

The NK sore finally got in touch with us and although there was
some delay in the shipment ft will ail turn out well before long.

For your question of a suitable visiting lecturer in bacteria!
genetics ! would strongly recommend Dr. M.L. Morse, Webb Building,
University of Colorado Medical Center, Denver 20, Colorado. He was a
very productive student of mine and was a very effective researcher in
the analysis of transduction of Gal factors by phage lambda. You will
find papers under his authorship among the reprints sent from this labora
tory. He has been working at Denver sufficiently Tong now that he might
well be interested in a break especially as he took no postdoctoral fellow-
ship between his studies and his position there.

AS ever,

Joshua Lederberg
