This is a valuable little manual with discussion of clinical material arranged on an anatomic basis. There is a brief chapter devoted to a summary of x-ray physics, technic and radiographic difficulties. The amount and wealth of clinical material presented is surprising for such a small volume and speaks for the careful organization and singular clarity of the book. The reproductions of the roentgenograms are excellent and the normal and pathologic details are carefully pointed out. Occasionally a small line drawing appears further to illustrate a point. The subject matter is almost wholly in outline form, permitting rapid gleaning of the essential diagnostic and significant features without a host of technicalities. Although more than half the book is devoted to bones and joints, other systems are not neglected and differential diagnosis is emphasized.
