Pauling expresses his disappointment that he was unable to attend Pugwash, as he had committed to lecturing in France during that time.

"You know that in May I wrote an appeal to stop bomb tests, as a first step toward more general disarmament and the prevention of a nuclear world war, and that this appeal was signed by more than 2000 American scientists. I have now decided, after having received unsolicited statements of agreement from scientists in other countries, to extend the appeal to cover the whole world, and I am in the process of getting scientists in all countries to sign the appeal", which Pauling encloses (not present). He expresses hopes that BR will sign.
