Dear Joshua:

The reference on phage induced variation in coli is
&@ monograph by Hoder called "Bakterienveranéerung durch Bak-
teriophazewirkung", published in Berlin in 1932, The only
place I know where you can get it is the library of the New
York Academy of Medicine in New York City.

Things are going very well here and I hope you find
your new set-up the same,

Sincerely,

Barry Commoner
