"In visiting the schools next day, the propriety of preparing a class or two of children for the public meeting was suggested and approved of; and the day-teacher being applied to, gave Mr Gall a list of six of his boys for the purpose. With these children he met on Monday; and after instructing them in the doctrines of the Gospel, and teaching them how to draw lessons from Scripture, he began to teach them some parts of natural philosophy, and to draw lessons also from these. Their aptness, and eagerness to learn, suggested the idea of selecting one of the sciences, and confining their attention principally to it, for the purpose of ascertaining how much of the really useful parts of it they could acquire and learn to use, in the short space of time which must intervene between that period and the hour of meeting. Considering what would be most useful and interesting, rather than what would be most easy, he hastily fixed on the science of anatomy and physiology, and resolved to mark the time during which they were engaged with him in learning it. These lessons were altogether oral and catechetical,--as neither he nor the children at that time had any books to assist them in their labours. "The method adopted by Mr Gall in communicating a knowledge of this important and difficult science to these school-boys, was strictly analytical;--classifying and connecting every part of his subject, and bringing out the several branches of the analysis in natural order, so that the connection of all the parts was easily seen, and of course well remembered. An illustration of his method may induce some parents to try it themselves.
