Originally published in 1928 as part of the Cambridge Comparative Physiology series, this book examines whether all muscular contractions use essentially the same processes regardless of the type of muscle in question. Ritchie uses an isolated muscle from a frog to investigate whether the chemical and physical causes of a simple muscle twitch can be responsible for the movements of all muscles. This book will be of value to anyone with an interest in the history of science or comparative physiology.
