Dear Dr. Lederberg:

I have now had opportunity to go over the reprint on bacter-
ial variation which you sent me some weeks ago, during my
prolonged absence from the Laboratory. I find it very in-
teresting indeed, and I am wondering if you could send me

a reprint of your paper listed as No. 5 in the Bibliography?
I don't seem to have encountered this one before, and it
certainly sounds interesting.

Thanking you very much indeed, and trusting that I shall
see you in Baltimore next week, I am, with kindest personal
regards,

Sincerely yours,

Katee Lely,

Ralph R, Mellon, M. D.
