Preface

These lectures are designed to present a complete exposition of the subject of Physical Diagnosis so far as it relates to diseases of the Chest, Throat, and Nasal Passages; to give the essential symptoms of each disease; to point out the symptoms and signs which are of most value in a differential diagnosis; and to outline briefly the proper treatment for the various affections. The anatomical characteristics and the causes of these diseases have been pointed out wherever they are of special value in enabling the reader to understand the physical signs, or to properly apply remedial measures. When these lectures were delivered, nothing was said about treatment, but in order to enhance the value of this work to both physician and student, I have appended to the consideration of the diagnosis of each disease, an outline of the treatment which I have found most satisfactory. In so doing, I have not even mentioned many methods of treatment of more or less value which have been recommended by other physicians.

In the preparation of these lectures I have availed: myself of every source of information at my command,, and I hope that little has been overlooked which would be of value to the student or practitioner. The study of this subject for several years, in connection with my lectures, and a large personal experience with these affections have enabled me to discriminate as to the relative importance of different signs and to detect numerous exceptions to the general rules. These exceptions, some

of which are extremely rare, are of little importance to the general practitioner, and the study of them is a positive injury to the student unless their true significance is understood. Matter relating to them has, therefore, been set in small type, so that it may be omitted until the student has become thoroughly familiar with the facts that are essential.

The nature of these lectures which contain information gathered from many different sources by study and by personal observation, and the fact that much of which they treat has long since become public property, renders it impossible for me in every instance to give the credit to individual authors which I desire, but I freely acknowledge my indebtedness to all who have preceded me in this field. I am indebted to the courtesy of Doctors J. Solis Cohen, of Philadelphia, and Lennox Browne and Morell Mackenzie, of London, for permission to use some of the cuts which illustrate their works. I take special pleasure in expressing my obligation to my clinical assistants, Doctors Philip Leach, W. H. Taylor, and J. T. Eggers, for valuable aid in the revision of jny notes.

Messrs. Sharp & Smith, of this city, have kindly furnished electrotypes for the illustrations of instruments.
