The author discusses the classification of schizophrenic forms ending with defect. He brings numerous clinical descriptions to substantiate an elaborate classification of defects. His point of view is essentially "biologic" in that he, like most German psychiatrists today, attempts to separate genetically linked groups within clinical entities. The work is purely descriptive and classificatory. It bears the stamp of the Kleist concept of organic system defect in the psychoses and ignores the recent advances of psychologic studies of schizophrenia.
