How the Mind Has Banished It

By H. ADDINGTON BRUCE
Author of "The Riddle of Personality,” “Scientific Mental Healing,” “Woman in

the Making of America," "Sleep and Sleeplessness,” and other volumes

-EDITORS' NOTEHYSTERIA! That is what Mr. H. Addington Bruce

calls the strangest of all diseases

. It is primarily a disease of lost memories-one of the most peculiar afflictions that comes to the human being—and the effectiveness of its treatment by mental means, the only means that ever are successful in handling it, usually depends on the skill with which these memories are recovered by the physician, so that he may know exactly what it is that he must suggest away. Mr. Bruce cites some remarkable cases in his article--the result of long research. Aside from being informing and valuable to the layman as well as the physican, it is unusually entertaining.
