This book is one of a series of psychologic phantasies which have been published from time by the Open Court Company. Professor Ribot first published his studies of the diseases of personality in Paris, 1884. The fact that the book passed through four editions gives ample proof of its value to psychologists.
The work is divided into four chapters devoted to Organic Disorders, Affective Disorders, Disorders of the Intellect, Dissolution of Personality, respectively.
The author gives a number of observations of cases of spontaneous alterations of the "Ego," which he thinks to be a more rational basis for the study of the morbid manifestations of personality. His deductions from a psychologic standpoint are clear, logical and concise, and will be read with profit by those interested in this branch of science, and familiar with its peculiar phraseology.
