The Natural Development of the Child

They emphasise the striking fluidity of the histological pitture in their cases and condemn any attempts at rigid classification. This case of lymphosarcoma has been presented principally because of the curious form of the liver metastases, and without being too dogmatic, the title "Pseudo-Leukaemic Lymphosarcoma" is advanced for the condition. SUMMARY 1. The histological and general pathological features of lymphosarcoma are described. 2. A case of lymphosarcoma showing several unusual features is presented. 3. The unusual features of this case are mentioned and the lymphoid tissue tumours in general are discussed. THE fact that Dr. Bowley's book has run to three editions since its first appearance in 1942 is a measure of its usefulness. It is intended for the guidance of parents and teachers, but could well be included in the library of the general practitioner, who is constantly asked as to whether such and such a child's development is normal; in that of the padiatrician; and more particularly in that of the psychiatrist, who will soon be at sea in dealing with the abnormal child if he does not have a clear idea of what is the normal development in children. This latter the book provides in a clear, concise, and readable manner, together with a comprehensive bibliography on each stage of development, which will permit of more intensive study. The enlargement of the chapter on Adolescence in this edition is an improvement, and, considering the times we live in, it is perhaps wise that the chapter on Children and the War remains. Some of the definitions in the glossary might be improved. For instance, masochism is not "pleasure of inflicting pain on oneself," but pleasure obtained from pain inflicted on oneself," traumatic is not "liable to cause shock," but "resulting from injury," and metabolic is not " relating to digestion," but relating to the biochemical processes of nutrition and excretion."
