Manic-Depressive Insanity and Paranoia. By Professor Kraepelin, translated by R. Mary Barclay. Published by  E. & S. Livingstone. Edinburgh, 1921. Pp.  280. Price £I net.

Dr. Barclay, the translator of these chapters on maniac-depressive insanity and paranoia from Professor Kraepelin's text book of Psychiatry has rendered a distinct service, and one which only those who have translated similar material can adequately appreciate. She has previously translated the chapters on dementia praecox and paraphrenia, reviewed in the January number of THE PSYCHOANALYTIC REVIEW. These two books represent the distinct contributions of Professor Kraepelin to psychiatry, dementia praecox and the manic-depressive psychosis being the specific formulations of lasting value which he succeeded in reaching as a result of his extensive clinical experience extending over many years. They constitute the best descriptive material of these psychoses extant and are invaluable in the library of every psychiatrist and must necessarily serve as the classical starting points for further dismemberment and for interpretative formulations. Whatever may be the future status of these nosological entities, the descriptive material which he has collected will remain of inestimable value.
