Sir, - Your correspondent, Gay Brocklesby (December 21st) provides the address in Washington to which people might write to thank George Mitchell for the huge debt we owe him for his leadership, and for his provision of hope with a smile over the recent years. In fact he has an address in Ireland at this university, where we are proud to have him as our Chancellor. - Yours, etc., Dr Allan H. Fawcett,
Queen's University, Belfast 7.
