“…Although most of the work has little direct interest for psychologists, attention may be called to a number of sections. The first volume, published in 1910, contains, for ex-ample, a brief chapter on the physiological principles of muscle mechanics, by R. du Bois-Reymond (10), with a description of certain models of muscle and joint action; a chapter on the physiological phenomena attending mental processes, by E. Weber (44), containing a brief summary of the findings in Weber's book on the same topic published in 1910. The second part of the first volume has chapters by Henschen on central visual disturbances (22), and by Barany on nervous disorders of the cochlear and vestibular apparatus (4); and a chapter on psychotherapy, 53 pages long, by Mohr (30), taking up systematically and somewhat fully the methods of hypnosis, waking suggestion, auto-suggestion, and other methods termed Ablenkung, Uberrumplung und Einschuchterung, a method by painful impressions, methods of education and persuasion, Willtnstherapie, the therapy of occupation, constitutional treatment, psychoanalysis (here very briefly treated).…”
