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,
