Rotblat thanks BR for his letter of 20 September and his offer to contribute £50 to the cost of expenses of the congress, though Rotblat hopes there will be no need to make use of BR's offer.

"Although the number of acceptances has been fairly small, we feel that it may be worth while to go ahead with the conference. In accordance with our original suggestion to invite other people if we have too many refusals, we suggest the following five be invited: —Dr Oppenheimer, Dr Albert Schweitzer, Professor Rajewsky of Germany, Professor Thirring of Austria and Professor Burgers of Holland."

Rotblat encloses letters addressed to them, asking BR to sign them if he agrees with the suggestions, and to send them back to Rotblat who will mail them (not present).
