This antiquarian book contains the first volume of Lewis R. Wolberg’s "Medical Hypnosis", being a comprehensive exposition on the principles of hypnotherapy. This book is the result of experimental work with hypnosis in the treatment of various emotional difficulties, and attempts to delineate the utilities and limitations, as well as advantages and disadvantages, of hypnotherapy. "Medical Hypnosis – The Principles of Hypnotherapy" is highly recommended for those with an interest in the practical applications of hypnosis, and it would make for a worthy addition to collections of allied literature. The chapters of this book include: “The Nature of Hypnosis”, “Pathological Theories”, “Psychologic Theories”, “The Technique of Hypnosis”, “Susceptibility to Hypnosis”, “Suggestibility Tests”, “ The Depth of Trance”, “The First Hypnotic Session”, etcetera. Many antiquarian books such as this are increasingly hard to come by and expensive, and it is with this in mind that we are republishing this book now in an affordable, modern, high quality edition. It comes complete with a specially commissioned new introduction on hypnosis.
