A Dictionary of Psychological Medicine, Giving the Definition, etymology and synonyms of the Terms used in Medical Psychology, with the Symptoms, Treatment, and pathology of Insanity, and the Law of Lunacy in Great Britain and Ireland

THIS Work, the first of the kind which has been attempted, aims at providing information, more or less systematic, in regard to the Definition, Etymology and Synonyms of the Terms used in Medical Psychology, with the Symptoms, Treatment, and Pathology of Insanity, together with an abstract of the Law of Lunacy in Great Britain and Ireland. A large number of short Definitions of words have been introduced. Articles of greater length treat of the various Forms of Mental Disorder and the most important subjects which fall under Psychological Medicine. The Philosophy of Mind is expounded in a separate Introductory Article, and is not lost sight of in the Shorter Definitions and other Articles ; but it is to be borne in mind that the fundamental aim of the Dictionary is directed to Morbid Psychology, and not to Mental Science in its ordinary restricted sense.

An account is given of the methods of Psycho-Physical Research which have been introduced in recent times into Psychological Laboratories established in various Universities in Europe and in the United States; also of the results which have been reached in regard to the Reaction-time of Mental Phenomena. The History of the Insane, and the reforms undertaken to ameliorate their condition in various countries of the world, have been fully given. An important feature of the Dictionary is the introduction of Bibliographical References (Foreign and English) in connection with the most important Articles ; and, in addition to these, a copious Bibliography of English Psychological Medicine will be found at the close of the Work. Illustrations of the various Types of Insanity are given, and, in addition, Engravings intended to facilitate the understanding of other subjects described in the Dictionary. The study of Psychological Medicine has been so gi-eatly extended in recent years at home and abroad, that a literature has sprung up of alarming dimensions, containing a record of a vast number of clinical observations, ingenious theories, and, as a necessary consequence, the coinage of a multitude of terms. It is open to question whether the relative amounts of the tares and the wheat are in exactly the proportion we should desire, but it is not open to question whether the Medical Psychologist stands in need of a work of reference to which he can refer for information. That any such work can be complete is too much to expect. In the present instance there must necessarily be some omissio
