Rotblat thanks BR for his letter and contribution towards the expenses of the Pugwash Conference.

Rotblat expresses concern with the poor response to the invitations to Pugwash, as there still has been no response from the last batch of letters sent out. Rotblat proposes inviting Dr. Brock Chisholm, former president of the W.H.O. as the conference will be held in Canada, as well as renewing Hahn's invitation.

Rotblat encloses a copy of a statement on the strontium hazard issued by the A.S.A. (not present).
