Deliberate popularization of mental pathology, its history, progress and treatments, which contains a good deal of fascinating, little known material. One has a feeling that the author has given stress according to her interest in -- or the dramatic interest of -- the material, rather than its medical importance. She starts with the story of the evolution of the brain, the discovery of its functions, the pathfinding of Paul Bross; then on to the work of the late 19th century when Mesmer, a true scientist, and Charcut, a chariatan, laid the foundations of psychiatry. After the war Freud brought psychiatry into its own. Brief treatment of his successors and one theories; more extensive detail on the physiological handling of insanity, of Wagner Jauregg and paresis, of Baked and his insulin shock treatment, of electricity, of glandular injections, and so on. Told in the vernacular, this concentrates a good deal of dynamic medical discovery into form for popular consumption.
