This book publishes the 1932 Adolph Gehrmann lectures in hygiene at the University of Illinois College of Medicine. Dr. Campbell brings to his problem not only an extensive clinical experience, but also great facility in presenting succinct conceptions. The book includes brief outlines of some forty-three cases of individuals suffering schizophrenic disorders. The material is not intended so much to deal with schizophrenia as to use schizophrenic phenomena to point the author's formulation of mental hygiene and good living.

The first chapter, 'The General Field and the Special Territory', first indicates the difference between the hygiene of impersonal factors and mental hygiene with its consideration of the personality and social situation. Mental disorder is considered as human nature working under difficulties and the schizophrenic territory is recognized as the particularly promising section for teaching purposes. The adoptive value of schizophrenic behaviour and ideas completes this lecture—with all due courtesy
