Dear

   I just received from Russ Doolittle of the University
of California,  San Diego a chain letter originated by Professor
Ito in Japan.  This letter is an attempt to mobilize world
scientific opinion in favor of total nuclear disarmament.
Professor Ito's idea is that if each scientist will send his
or her own version of the letter you are now reading favoring
universal nuclear disarmament to ten of his or her colleagues,
asking them again to spread the chain,  that an extraordinarily
large number of signatures could be accumulated in favor of
this vital move.  Could you please send your letter to ten
colleagues (no doubt there will be some overlap among lists)
and a copy of your letter to Professor Y. Ito (Laboratory of
Applied Entomology and Nematology, Nagoya University, Furo-cho,
Chikusa-ku, Nagoya, Japan)?  I enclose the list on which my
name appeared as well as my list of ten.

Sincerely,

Dr.  Christian B. Anfinsen
