Rotblat thanks BR for his cheques of £100 and £400 to go towards secretarial assistance in the Pugwash London office.

"Writing now personally I should like to tell you how deeply moved I was by your letter of yesterday. It came at a time when I was very much downcast about the difficulties in Pugwash work and this type of letter makes me feel that it is all well worthwhile.

It has given me an enormous stimulus to carry on with the struggle."
