BR thanks Rotblat for his letter of 7 January. Typed on the verso of Rotblat's letter.

He agrees completely with Rotblat's sentiments regarding the Test Ban Agreement in Geneva, and feels that holding a conference as soon as possible is desirable given this situation. "If scientists cannot agree about tests, they are not likely to agree about anything else. I do not know whether blame is to be attached to either side in the breakdown of negotiations. I had hoped that the breakdown was not final and that agreement was still possible."

BR has signed and sent the two letters Rotblat enclosed.
