The proper management of our own bodies is even more essential to our happiness and well-being than the proper management of the land, and I hope that this book will be no less welcome to students and physicians than to the great mass who for lack of knowledge of of attention do not wholly avail themselves of the freely offered gift of sleep. This book may be useful to many who find it difficult to harmonize their lives with their surrounding, and my bring to man a happier view of the ways of God to man.
