ABSTRACT
The general observation of child-life about one, the gathering of unrelated observations and incidents.… the study of children’s diaries and letters, and the wide reading of autobiographies, will quicken our interest, broaden our sympathies, and give us a larger understanding of special instances. However, if such a work is not accompanied by direct and well-ordered observation, by experimentation and statistical study, leading to some general quantitative results, it is apt to leave us with a feeling that human life is not amenable to law.
