The oldest 'May Meeting' in the world opens next Friday, when the Society of Friends holds its 200th yearly meeting at its new headquarters in the Euston Road. It is appropriate, therefore, that there should be a Quaker speaker tonight. Mr. Carl Heath is Secretary of the Friends' Council for International Service, and he is particularly in touch with Quaker work in Europe, where his idea of 'Quaker Embassies ' has led to the formation of centres in Paris, Geneva, Vienna, Berlin, Warsaw, and other cities. He is the author of several books, including one on 'Religion and Public Life.'
