As we come to the end of the Symposium, it is my pleasant duty to thank all those who have made this occasion and these events possible. I must, of course, single out first of all the writers who consented to speak on the different panels, and then those who responded to them. I think the consensus of opinion is that all of the sessions have been exciting, and some have been enormously exciting and have made this Conference worthwhile.

I must also, of course, thank the people who ran the local Working Committee.
