The Centenary Meeting of the Royal Medico-Psychological Association should have taken place in 1940. I was honoured in 1939 by the Association nominating me as President-Elect. Much has happened since then, and for five years we have met under the able presidency of Dr. T. C. Graves, whose inaugural meeting had necessarily to be a short one; it was held in London and was limited to the delivery of his presidential address. I feel that we owe a great debt to Dr. Graves for his constant attendance and work, often under difficult war conditions.
