Writers of authority will present original communications and reviews of important books; noteworthy articles in periodicals out of convenient reach of the general public will be republished; reports of surveys, special investigations, and new methods of prevention or treatment in the broad field of mental hygiene and psychopathology will be presented and discussed in as non-technical a way as possible. It is our aim to make MENTAL HYGIENE indispensable to all thoughtful readers. Physicians, lawyers, educators, clergymen, public officials, and students of social problems will find the magazine of especial interest.
