EDITORIAL ANNOUNCEMENT This volume is one of a series of Monograph Supplements to the Journal of Criminal Law and Criminology. The publication of the Monographs is authorized by the American Institute of Criminal Law and Criminology. Such a series has become necessary in America by reason of the rapid development of criminological research in this country since the organization of the Institute. Criminology draws upon many independent branches of science, such as Psychology, Anthropology, Neurology, Medicine, Education, Sociology, and Law. These sciences contribute to our understanding of the nature of the delinquent and to our knowledge of those conditions in home, occupation, school, prison, etc., which are best adapted to elicit the behavior that the race has learned to approve and cherish. This series of Monographs, therefore, will include researches in each of these departments of knowledge insofar as they meet our special interest. It is confidently anticipated that the series will stimulate the study of the problems of delinquency, the State control of which commands as great expenditure of human toil and treasure as does the control of constructive public education.

Very little advancement in the treatment of delinquents or criminals can be expected if typical characteristics and their bearings are not understood. The group that our present work concerns itself with is comparatively little known, although cases belonging to it, when met, attract much attention. It is to all who should be acquainted with these striking mental and moral vagaries, particularly in their forensic and psychological significances, that our essay is addressed. In some cases vital for the administration of justice, an understanding of the types of personality and of behavior here under discussion is a prime necessity.
