In presenting a preliminary consideration of the subject of mental diseases as a public health problem the author is actuated by no other motive than that of stimulating the undertaking, at some future time, of a comprehensive investigation and survey of an important field which has never been systematically and adequately studied in the past. Under existing circumstances the facts necessary for an intelligent discussion of this question are unfortunately not obtainable. We have, as will be shown, practically no information whatever as to the incidence of mental diseases in the community. Hospital statistics are still in such a chaotic state that we are not even in a position to speak authoritatively of that part of the population which is entirely within our supervision and control in institutions. Before any progress can be hoped for we must at least have at our disposal accurate data relative to the patients within the walls of our hospitals. This presupposes a uniform scheme of statistical reports based upon some common viewpoint. Adequate preparations for this undertaking have been made by the American Psychiatric Association and the National Committee for Mental Hygiene. Every hospital for mental diseases in the country has been urged to cooperate in this movement. To show the necessity for more actively prosecuting this research has been one of the principal purposes of this book.

In elaborating somewhat briefly the conception of the various psychoses generally accepted by American psychiatrists, and for that reason included in the classification adopted by the Association, every effort has been made, as far as possible, to show the steps which have led up to present developments. The author has endeavored to confine himself to reflecting the views of others throughout and has used actual quotations from recognized authorities as far as was deemed advisable. In the discussion of the various psychoses frequent references will be noted to the description of the various clinical groups contained in the manual prepared by the Committee on Statistics for the American Psychiatric Association. As is shown in the manual, these definitions and explanatory notes were formulated by Dr. George H. Kirby.

Special reference should be made to the important contributions to the literature of psychiatry of such well-known American writers as Meyer, Hoch, Kirby, White, Barrett, Campbell, Southard, Peterson, Diefendorf, Jelliffe, Paton, Salmon, Russell, Buckley, Rosanoff, Orton, Singer and many others. The work of Kraepelin, Bleuler, Nissl, Alzheimer, Freud, Jung, Stekel, Janet and others abroad has exercised an influence on the psychiatry of the day which must be recognized. We are very largely indebted to Pollock and to Furbush for the available information relating to the incidence of the various psychoses in this country. To the American Psychiatric, for many years the American Medico-Psychological, Association we owe an exhaustive historical review of the institutional care and treatment of mental diseases in the United States and Canada.

Obviously this work was not intended as a textbook, nor was it designed to serve the purpose of one. It is an appeal to those who are already familiar with the fundamental principles of psychiatry. For that reason the interpretation of mental mechanisms given so much space in textbooks has been entirely omitted and no reference is made to the treatment of the individual psychoses. Such reliable statistical data as could be gathered from recent hospital reports and publications have been utilized in full. The following institutions were represented in this study:

1. Massachusetts—fourteen hospitals (1919-1920): Boston State Hospital, Boston; Bridgewater State Hospital, State Farm; Danvers State Hospital, Hathorne; Foxborough State Hospital, Foxborough; Gardner State Colony, Gardner; Grafton State Hospital, North Grafton; McLean Hospital, Waverley; Medfield State Hospital, Harding; Monson State Hospital, Palmer; Northampton State Hospital, Northampton; State Infirmary, Tewksbury (Mental Wards); Taunton State Hospital, Taunton; Westborough State Hospital, Westborough; Worcester State Hospital, Worcester.

2. New York—thirteen hospitals (1912-1919): Binghamton State Hospital, Binghamton; Brooklyn State Hospital, Brooklyn; Buffalo State Hospital, Buffalo; Central Islip State Hospital, Central Islip; Gowanda State Homeopathic Hospital, Collins; Hudson River State Hospital, Poughkeepsie; Kings Park State Hospital, Kings Park, L. I.; Manhattan State Hospital, Ward's Island, New York City; Middletown State Homeopathic Hospital, Middletown; Rochester State Hospital, Rochester; St. Lawrence State Hospital, Ogdensburg; Utica State Hospital, Utica; Willard State Hospital, Ovid.

3. Twenty-one hospitals in fourteen other states:

Arkansas—State Hospital for Nervous Diseases, Little Rock (1917-1918).

Colorado—Colorado State Hospital, Pueblo (1917 and 1918).

Connecticut—Connecticut State Hospital, Middletown (1917 and 1918); Norwich State Hospital, Norwich (1905-1918 inclusive).

Maryland—Springfield State Hospital, Sykesville, 1919; Spring Grove State Hospital, Catonsville, 1918 and 1919.

Michigan—Pontiac State Hospital, Pontiac, 1917 and 1918; State Psychopathic Hospital, Ann Arbor, 1917 and 1918; Traverse City State Hospital, Traverse City, 1917 and 1918.

Montana—Montana State Hospital, Warm Springs, 1917 and 1918.

New Jersey—Essex County Hospital, Overbrook, 1918.

Pennsylvania—State Hospital Southeastern District of Pennsylvania, Norristown, 1919.

South Carolina—South Carolina State Hospital, Columbia, 1918.

Utah—State Mental Hospital, Provo, 1918.

Vermont—Vermont State Hospital, Waterbury, 1917 and 1918.

Virginia—Central State Hospital, Petersburg, 1919; Western State Hospital, Staunton, 1919.

Washington—Eastern State Hospital, Medical Lake, 1917 and 1918; Northern State Hospital, Sedro Woolley, 1917 and 1918.

West Virginia—Spencer State Hospital, 1917 and 1918; Weston State Hospital, Weston, 1917 and 1918.

These institutions may, I think, be looked upon as fairly representative of the hospitals of this country. Based on their official reports an analysis has been made of over seventy thousand consecutive first admissions.

There is no disposition on the part of the writer to overestimate the value of statistical studies. Our conclusions should, however, be based as fully as possible on facts rather than on abstract theories or individual observations alone. The social, economic and clinical aspects of mental diseases must all be given adequate consideration if psychiatry is to fulfill its obligation to the community and assume a dignified rÔle in the advancement of modern medicine.
