Rotblat asks BR if he will sign and send another set of letters (not present).

He writes about the next topic of Pugwash being biological weapons, which the committee had discussed as a possibility at their last meeting. Based on his conversations with experts on biological weapons Rotblat writes, "... it appears that it will be practically impossible to deliver biological weapons. On the other hand, it may be quite easy for small nations to produce a sufficient amount of germs or toxins to be of great nuisance value in a local war."

Rotblat comments that he enjoyed BR's TV appearance the previous week.
