Dear Dr. Lederberg!

Many thanks for your very interesting reprint.

I got it timely. I envy all of you american geneticists for the
possibility on your undisrupted working and congratulate you all
on your new and most promising work on microgenetics. We are at
‘least half a dozent years behind and I know from my drosophila-

work what that means.

With my best regards

ours
