A Synopsis of Blood Grouping Theory and Serological Techniques

THIS latest edition of Tredgold and Soddy's Textbook of Mental Deficiency in many ways rcpresents a healthy departure from static descriptions of pathological states alone to a more dynamic approach to the understanding of problems of social and psychological adjustment in mentally defective individuals. This owes much to the lessons learned from Child Psychiatry, and indeed the chapters on normal mentality, the subnormal mind, and disorders of relationship formation would be equally relevant in a textbook on that subject. The descriptions of child development and its anomalies are essentially clinical, and might not satisfy the academic psychologist, but they are none the less valuable for the positive therapeutic approach embodied in them.
