In the experiment made upon the adult criminals in the County Jail of Edinburgh, the pupils acquired easily and permanently a thorough knowledge of the history contained in the Book of Genesis. "They gave a distinct account of its prominent facts, from Adam, down to the settlement in Goshen, and shewed by their answers, that these circumstances were understood by them, in their proper nature and bearings. They gave, in the next place, a connected view of the leading doctrines of revelation; when their answers evinced, most satisfactorily, that they apprehended, not merely each separate truth, but that they perceived its relation to others, and possessed a considerable knowledge of the divine system as a whole. They were also examined upon several sections of the New Testament; where their answers displayed an equally clear and accurate knowledge of the subject." These persons, be it observed, belonged to a class of individuals, who are generally considered to be peculiarly hostile to the reception of information of this kind, and certainly who are least able to comprehend and retain it; and all this, besides other portions of knowledge, on which they were examined during the experiment, was communicated with ease by about twenty hours teaching. By the experiment made at Aberdeen, upon children the most ignorant that the Committee of Clergymen could find among the several schools in the city, it was ascertained, that after only nine or ten hours teaching, they had not only received a thorough knowledge of "several sections of New Testament History," but that they had acquired a knowledge of all the leading events included in the Old Testament History, from "the death of Moses, downwards to that of the revolt of the Ten Tribes in the reign of Rehoboam. Here they distinctly stated and described all the leading circumstances of the narrative comprised in the 'First Step,' whose brief but comprehensive outline they appeared, in various instances, to have filled up at home, by reading in their Bibles the corresponding chapters." The efficiency of this form of analytical teaching, as exhibited in successive steps, when employed for the purpose of teaching a knowledge of civil history and biography, was also proved with equal certainty;--for these same children showed a thorough knowledge of that portion of the History of England embraced by the reign of Charles I. and the Commonwealth; and in biography, the life of the late John Newton having been employed for the purpose, they shewed such an acquaintance with the leading facts, and the uses to be made of them, that the reverend gentlemen in this report of the experiment say, that the children had "to be restrained, as the time would not permit."
