Dear Dr. Lederberg,

In looking over some of my old
semirars, I just happened to find the enclosed copy of

"Sex and sex determination in the animal and plant kingdoms"
In Oct. 1952, you once asked me whether Is till had such a

copy which I did not find at that time. If you would like to,
you may keep this copy because I have the German original.

Sincerely yours,
Peer fce lucote,

Cecilie Leuchtenberger,
