Rotblat asks BR if he would like him to reply to Valls' letter.

He is worried about an article written by Walter W. Marseille from the Bulletin of Atomic Scientists which is very anti-Pugwash. "I agree with Rabinowitch that it should be accompanied by an article representing the opposite view and naturally nobody could do it better than yourself. I wonder, therefore, whether you could possibly find the time to write a short article in answer to Mr. Marseille".

There is a postscript requesting BR to sign and send the enclosed letters (not present).

A digital print of the carbon of this letter is available in Box 16.79, RA3 1816e, document no. 26.
