Rotblat thanks BR for his letter and cheque of £50.

He writes that Professor Thirring and Dr. Bruno Kreisky, a member of the Austrian Cabinet, will also be attending the committee meeting of 2 June. Because of this, the party will be too large to travel to North Wales, and Rotblat has not "the heart" to ask BR to come to London unless he has other reasons to come.
