Dear Dr. Lederberg:

Recalling your thoughtful kindness in
joining other Nobelians in expressing to Pope
Paul VI your concern over the world's soaring
population, I thought you would be interested
in the enclosed reprint.

I would appreciate, for possible publication,
a brief--a sentence or two--expressbon of your
thought re the timeliness and helpfulness of
this article.

Thanking you in advance for your kindness,

Ever cordially,

SAAR
