Rotblat suggests sending out three more invitations to Pugwash, as very few Americans have accepted. "One of these is H.J. Muller who previously refused but perhaps might be inclined to accept now. Dr. Price is the chairman of the Federation of American Scientists. If you approve of these letters would you kindly sign them and send them off" (not present). Rotblat informs BR that his article will be published by the New Scientist and will appear in the following week's issue, with Angus Maud taking the opposite view.

There are handwritten notes on this letter, stating "Letters signed and sent" and "Proofs returned 22 March 3/6/0 sent for reprints."

A copy of the carbon of this letter is located at record 7484.
