The XXX Congress of the International Union of Physiological Sciences took place in Vancouver, Canada, in July 1986; and this Volume contains a selection of the Review Lectures which formed part of the Congress programme. They cover most of the areas of contemporary physiology and were presented by distinguished scientists from many parts of the world. An innovation at this Congress was the inclusion in the programme of a number of lectures devoted to historical subjects. These lectures attracted large audiences at the meetings, and three of them also appear in this book. Finally, the Plenary Lectures which formed part of the opening and closing ceremonies and which deal with some aspects of Canadian physiological history, find a place here as well. The Editors are grateful to all of the authors who provided the manuscripts which go to make up this book, and to John Donald for his invaluable assistance in the preparation of the final text; as well of course to all of the contributors whose participation made the Congress the success which it was. It is hoped that this Volume will provide a useful memento of the event.

Advances in Physiological Sciences, Volume 20: Advances in Animal and Comparative Physiology covers the proceedings of the symposia of the 28th International Congress of Physiology. The book discusses several studies that tackle issues about the advances in animal and comparative study. The text is comprised of 61 chapters in which Chapter 4 and the succeeding chapters are grouped into eight parts based on the topic of the studies. The opening chapter explains sensory modalities beyond human perception, while Chapter 2 discusses trends in the physiology of domesticated animals. Chapter 3 reviews muscles in living animals, which is followed by topics grouped into parts. The first part deals with fetal homeostasis, while the second part discusses control of corpora lutea function of ruminant and non-ruminant domesticated animals. The third part deals with the comparative physiology of lactation in farm animals, while the fourth part tackles digestion in non-ruminant herbivorous animals. Parts 5 and 6 cover topic on diving, which includes metabolism, physiology, and control. The seventh part discusses phylogenesis of hormones and hormone receptors, and the last part covers neuromuscular transmission in invertebrates. Researchers whose line of work concerns the physiological properties of animals will find this book as a great source of related literatures.
