. “In presenting this book to the public the authors have in mind the need for brief but accurate account of the common mental defects and sociological factors encountered in study of adult criminals, and of delinquent children. From an extensive experience in criminological work, including the psychopathic laboratory and much expert testimony in court, they are convinced that many judges, lawyers, police officials and doctors will welcome the sort of information which is here given. They also have in mind the needs of social service workers, teachers, and students of sociology, and last, but not least, certain part of the general public, which is asking almost in vain for the explanation of the criminal and delinquent behavior which today, more than ever before, presents itself in every large community. The authors have not pretended to offer anything new to experts in the study of abnormal behavior, yet they hope that even some of these will find the case-histories, at least, interesting and perhaps valuable.”
