Powell thanks BR for his letter of 1957/07/18 (which is not in the Russell Archives). He is pleased the BR approves the statement issued at Pugwash and goes on to give him a report of the conference proceedings. In the conclusion of the letter he proposes attending a Quaker convention in Switzerland to see if they would be interested in sponsoring a later conference. Brock Chisholm, the Canadian, suggested this.
