Excerpt from The Tonsils and the Voice in Science, Surgery, Speech and Song Tonsils! What are they? What are their functions? Who knows? What textbook tells? I have made a research investigation, and this book gives the result. Lights and side-lights fell upon my path. Delicate, difficult, complex, technical questions of the voice arose. Two professions became involved. No treatise on the tonsils is complete unless it includes the questions of the voice, for the tonsils and the voice are inseparable subjects. This is the only work in which a systematic effort has been made to connect the viewpoints of both the medical and voice professions, in an orderly and authoritative manner. This is the only work on the subject published in any language. This is the only work in which, in addition to its physiological functions, the tonsil is treated as a mechanical body, and the action of its mechanism fully expounded. This work contains all the facts of a world's research on the structure, uses, disorders and treatment of the tonsils; many new facts in the science of the vocal art; and in addition, a full exposition of the modern hygiene of the tonsil, the hygiene of the voice, and the care and health of the nose, mouth and throat.
