Dear Doctor Lederberg:

My visit at the University of Wisconsin last
week was very enjoyable. I appreciate very much the
time that you spent with me and the extremely interest-
ing suggestions which you had to make concerning the

relationship of bacterial genetics to our research pro-
grame

I have sent 30 grams of Streptomycin Merck
Calcium Chloride Complex in five-gram ampules for your
studies on streptomycin resistancee This is our regu-
lar commercial material and should be useful in your
investigations.

Our best wishes for the Holiday Season and
for the coming New Year.

Sincerely yours,

Ws. Uordedf
