In the afternoon there was a symposium shared by the British Society for Digestive Endoscopy on 'Diagnosis of pancreatic disease' (Moderator, Dr Sheila Waller), and a clinicopathological conference on 'Progressive intestinal disease in an adolescent' (Moderator, Dr W. T. Cooke). The Sir Arthur Hurst Memorial Lecture was given by Dr A. F. Hofmann on 20 September.
