In the course of the World War unprecedented opportunities enabled psychiatry to make great strides. The movement for mental hygiene is developing direction, organization, and force. Psychiatrists no longer confine their activities within the walls of institutions for the insane, but are constantly organizing connections with general hospitals, schools, charitable organizations, courts of law, penal institutions, etc.
In the endeavor to keep this Manual abreast of progress and to maintain its usefulness to the student of psychiatry numerous changes and additions have been made in preparing the present edition.
New chapters, sections, or appendices, dealing with the following subjects, have been added: applications of psychology in psychiatry, psychoanalysis, applications of sociology in psychiatry, extramural psychiatry, psychoneuroses, hyperthyroidism, normal course of early mental development, Stanford revision of the Binet-Simon intelligence scale, Kent-Rosanoff association test, standard psychological group tests, and the classification of mental diseases adopted by the American Medico-Psychological Association.
The chapters, sections, or appendices, dealing with the following subjects, have been extensively rewritten: arrests of development, epilepsy, constitutional psychopathic states, chronic alcoholism, cerebro-spinal syphilis, lumbar puncture, and tests of the cerebro-spinal fluid.
The remaining chapters have also undergone careful revision with resulting numerous minor changes and additions.
The Index has been greatly amplified and, it is believed, rendered more serviceable.
Some of the alterations have been made as a result of criticisms and suggestions offered by reviewers, to whom grateful acknowledgment is hereby made.
In order to introduce all the above mentioned changes and additions it proved necessary to reset the entire book. The aim has, however, been adhered to of avoiding its growth beyond the proportions of a practical manual, convenient for frequent reference. By the use of somewhat smaller type and by making the pages a little larger the increase in thickness has been kept down as far as possible, although, of course, it could not be wholly avoided.
This Manual, as many know, first appeared in English in 1905, as a translation of the French Manuelde Psychiatrie by J. Rogues de Fursac. The special demands of American students have, through successive editions, led to changes and additions eventually affecting even scope and viewpoint. To-day the original French model still constitutes the nucleus around which this Manual has grown; yet it is but the duty of the American editor to acknowledge his full responsibility for its teachings.
It is the earnest hope of the editor and his collaborators that this Manual will continue to meet a growing demand, as, apparently, it has done in the past.
