This paper-bound volume is the second of a set of three dealing with physical methods of treatment in diseases of the ear, nose, and throat. The other two volumes will deal with the therapeutic use of light, electricity, radium, and inhalations; the present volume deals solely with roentgen rays. It is divided into two parts, the first devoted to general considerations of technique and dosage and the second to particular consideration of the outer ear, middle ear, nose (with accessory sinuses and nasopharynx), mouth, pharynx, larynx, and esophagus. The author presents his subject in succinct, concrete form. Illustrations and statistical data supplement the text. The bibliography of 48 references is confined to European publications, but the text reflects current American thinking as well. The book is recommended to those who read German.
