Dear Sira,

  During the smr I had the opportunity of working with Dr.
Waclaw Saybalski o# the Long Island Bio3.ogioal. iaborntories. it
became apparent tnat resis+&me to furadoxyl, NF-67, would mrvw
as an excellent st;idy in qumtitat.ive inheritance 3~ the bzictariufn
Escherichia coli.  The gemtic aspect of the resistance problem
was therefore relegated to ne.  Would it be possible to obtain
this chmical fro:n your eorpol*stion~

Sincerely yours,

Thomas C. Nelson
