OF THE DISEASES OF THE LARYNX BY DR. L. GRÜNWALD of Munich AUTHORIZED TRANSLATION FROM THE GERMAN EDITED BY CHARLES P. GRAYSON, M. D. Lecturer on Laryngology and Rhinology in the University of Pennsylvania With 107 Colored Figures on 44 Plates PHILADELPHIA AND LONDON W. B. SAUNDERS & COMPANY PREFACE. IN the preparation of this little Atlas of the Diseases of the Larynx the author has adopted the same plan as that pursued in his earlier Atlas of the Diseases of the Nose and Throat. Its object is to help the beginner in the art of observing and interpreting. As, however, a knowledge of the previous history of the disease and the examination of contiguous, as well as of more distant organs are indispensable for diagnosis, especially in this region, each picture is accompanied by the necessary data in the form of a short history. By adopting this method the author believes he has also presented a valuable aid to the physician who has few opportunities of seeing diseases of the larynx and yet wishes to be able to recognize them. At the same time a clearer mental image is obtained which may compensate for possible imperfections in the actual picture. The illustrations are arranged solely according to external appearances, without regard to the nature of the disease; partly in order to train the eye by comparing conditions similar in appearance, though differing widely in their true nature, and partly to make it easier to find the illustrations which most resemble the particular case 3 65603 to be diagnosed. Many well-known pictures, as, for instance, that of diphtheria, are therefore omitted. To prepare the student for this course in the theory and practice of diagnosis a short, systematic abstract has been added. In the author's opinion, a knowledge of the histology of morbid processes is most essential to a proper understanding of them. Twelve plates showing the most important elementary alterations have accordingly been devoted to this purpose. This department of pathology, which has been somewhat neglected in the text-books, affords the best means of arriving at clear, definite ideas. Figure 1 is taken from Luschka's work on anatomy, two illustrations of cadavers from the well-known atlas by Bollinger. All the other illustrations were prepared by the (academic) painter Mr. Keilitz, from sketches or preparations by the author, who takes this opportunity of expressing his thanks for the care and skill with which they were executed. THE AUTHOR. EDITOR'S PREFACE. IF it be true that "good wine needs no bush," 'tis certainly true that so good a book as this needs no preface. The American editor only ventures to add a few words relative to the method of instruction adopted in this book. It exemplifies a happy blending of the didactic and clinical such as is scarcely to be found in any other volume upon this subject with which we are acquainted. It is upon the value of the clinical portion of the work that the editor would dwell with particular emphasis. The beginner will find here a series of pathological conditions, illustrated with a remarkable fidelity to Nature, that it would undoubtedly require him a number of years to duplicate in actual practice; while the veteran, however rich his experience, will note a precision, a finesse in diagnosis that cannot fail to be instructive and, perhaps, even inspiring. The admirable translation, which is the work of Mr. R. Max Goepp, has been carefully compared with the original, and the editor's comments are intended as expository of, rather than as actual additions to, the text. C. P. G. 5 |
