Excerpt from Diseases of the Nose and Throat IT seems to the authors that the exceptional feature in this text-book of laryngology is the emphasis they have laid upon the etiology and path ology of disease. They have attempted to deal with nasal, pharyngeal, and laryngeal morbid processes from this standpoint, which necessarily involves also an extended consideration of the normal histology and physiology of the mucous membranes of the upper air passages. No logical and scientific discussion of disease can be carried on from any other basis. Much of this work in etiology and pathology rests on original investigation pursued for many years in the laboratory and the clinic by one of them. While in the various text-books of laryngology hitherto issued there has been some attempt to treat fully this aspect of the subject, the authors feel that the larger space they have devoted to it is entirely warranted, but they have sought to avoid any curtail ment of other interests; and the symptomatology and diagnosis, the topical and the operative treatment of diseases of the upper air passages have not been neglected in the attempt to give due consideration to their causes and consequences. In preparing the present work for the press, the authors desire to express in the preface their indebtedness to many colleagues to whom in the text also reference has for the most part been made. Naturally every such work is built on the foundation laid by others, but while fully appreciating this they have made no attempt to go further into the literature and history of the subjects connoted under the differ ent headings than was absolutely necessary, for two reasons. First, such excursions add enormously to the journey through our specialty in its most recent development and are themselves incomplete and not altogether adapted to the impartial and judicial expressions of opinion. Second, One of the authors has recently, from the press of the same publishers, issued a second edition of his History of Laryngology and Rhinology, in which this aspect of it is fully developed.
