Dear Josh:

I have just this minute received the four reprints
you sent me under your signature. Thank you for thinking
of me, I shall study them with more tnan ordinary interest
although I must confess that you geneticists are a little
esoteric for my taste.

We nave fallen heir to what was once a genetic exper-
iment, E. C. MacDowell's leukemia experiments. I shall be
very happy to tell you about it sometime.

I hope that you and your wife find the climate, hoth
academic and otherwise, to bs congenial. I imagine that you
would let me know if there are more than two Lederbergs.

Ada joins me in best wishes,

Sincerely,

SG: jk
