The special feature of this book is an historic one. It is the first to be printed in Spanish on the subject of Psycho-Analysis. The author, who is Professor of Psychiatry in the University of Lima, Peru, has already written a number of papers on psycho-analysis in the Revista de Psiquiatria, of which he is the Editor, and elsewhere. The present volume gives a succinct and accurate presentation of the subject, more particularly from the psychopathological point of view. He does not yet seem to be perfectly clear about the relative position of Freud, Adler and Jung, but this is a matter on which he probably will not long remain in doubt.
