Jaundice is much more than a clinical sign of liver disease. It is also a pathophysiological disorder. Through studying it we have come to a much better understanding of how the liver functions under normal and abnormal circumstances. In spite of several important advances in this field, it has not recently been the subject of a comprehensive and interdisciplinary review. This Symposium was held in Montreal on May 31 and June 1, 1974, and the experts who participated in it came together for the purpose of reviewing the current status of Jaundice. The Editors sincerely appreciate the outstanding contribution which these experts made to the Second International Symposium of the Canadian Hepatic Foundation. They are also particularly indebted to Valerie M. Price, Executive Director, Canadian Hepatic Foundation, for her invaluable role in the preparation of this publication. Carl A. Goresky Murray M.
