Roentgen Diagnosis and Therapy.

This is an enlargement of the author's manual of roentgen-ray technic, which appeared several years ago. That excellent but small work has now been elaborated and enlarged in a most satisfactory manner and presents the fundamentals of roentgen-ray technic, diagnosis and therapy. The presentation of the various phases of the work is logical, and the information in agreement with the most recent progress in roentgenology. The chapters on diagnosis are especially well written and the illustrations are of superior quality, pathologic changes being more clearly shown than is usually the case in such publications. The author is to be commended for having omitted material on antiquated apparatus of historical rather than practical interest, which so many works on the subject of roentgenology include. The book is a valuable addition to modern roentgenologic literature.
