Knowledge about the labyrinth has increased in the last few decades to a scale unthinkable even a short time ago. From a viewpoint of function, the labyrinth is divided into cochlear and vestibulosemicircular parts and the study of each of these divisions has been developed into an advanced discipline. Although this book is entitled "The Labyrinth," it deals with facts and problems of only a small, nonacoustic part of this organ. Its real objective is to summarize the methods presently available for testing the vestibular apparatus. To help the reader understand the subject, the first chapter is devoted to a brief survey of vestibular physiology. The second chapter is concerned with the common vestibular symptoms and phenomena that are elucidated by the laws and theories of vestibular function. All vestibular reflexes and clinical signs, such as vertigo, nystagmus, and other spontaneous signs, and the induced reactions, such as past pointing,
