First of all, a word about these reports. They are intentionally brief; this is because the press coverage summarised the main points quite adequately; because the people who were there need only a brief reminder; and because the people who were not there can receive full accounts from the people who went. With, a long general article on Congress as a whole we present here only a few points from each lecture, relying upon these to jog the memories of those who were there and to stimulate questions from those who were not.
