This compend discusses schizophrenia, cyclothymic psychosis, psychopathic personality, neurasthenia, hysteria, abnormal life reactions, mental abnormalities of children and young adults, suicide, psychosis due to internal diseases, brain diseases and epilepsy, psychiatric symptomatology and diagnosis, and psychiatric management. In an appendix Schneider discusses psychiatric system and structure of the psychosis as well as the diagnosis of schizophrenia and manic depressive insanity. The style is difficult because of the long and rather difficult structure of its sentences. There is an abundance of superfluous discussion. The bibliography is small.
