thorough-going longitudinal case studies made by the Juvenile
Psychopathic Institute of Chicago. In the latter material there
was found much of value bearing upon the subject of lying, false
accusation, and swindling of pathological character.

Our institute, later taken over officially by the Juvenile Court
of Cook County, was for five years maintained upon a foundation
provided by Mrs. W. F. Dummer.
