New York: D. Appleton and Company 1925. First American Edition. xv, , 619,  pages. 8vo. Blue cloth gilt. Missing the rare dust jacket. Bookstore ticket front flyleaf (Old Corner Book Store, Boston MA). A sound clean copy with perhaps a touch of fading to the spine panel. Old pencil notation regarding a later edition on rear endpapers. A few edge tears not affecting text. Near Fine. Cloth. 
Based on lectures the author gave to various audiences, "the purpose of the book is primarily a practical one: to enable the busy reader - whether teacher or probation officer of whatever the motive for his interest may be - to gain some notion how the criminal in the making may best be studied and handled." (from the preface).
There are many charts, diagrams and statistics. Also some photomechanically reproduced images of case studies (juveniles both young men and women), similarly of handwriting. The author is Professor of Education in the University of London, psychologist in the Education department of the London County Council, and author of "Mental and Scholastic Tests." It strikes me as the sort of book useful in understanding the thinking of the time in some detail, with stats to back up the author's conclusions.
