THE introduction of Dr. Jacobi has saved the author from the onerous task, ofttimes a graceless one, of writing extended prefatory remarks. It was in the course of some researches into the origin of the Child Protection movement in this country that I discovered how little attention had been paid to the historical aspect of this important question. This book represents really a process of elimination, behind which were many fascinating byways, alluring blind alleys, and seeming countless beckoning theories. Toward the last, for a person with human instinct writing on a humane subject, it was hard not to tilt. In the main, however, the author believes that he has hewed to the line.
