EDITED BY WILLIAM AND ROBERT CHAMBERS, CONDUCTORS OF CHAMBERS'S EDINBURGH JOURNAL, ETC. The success which has attended the efforts of Messrs CHAMBERS in the business of Popular Instruction, has induced them to undertake the duty of supplying a series of Treatises and School Books, constructed according to the most advanced views of Education, both as a Science and an Art, and answering in its parts and ultimate general effect to the demands of the age. Their COURSE will, as far as possible, embody the code and materials of a complete Elementary Education, Physical, Moral, and Intellectual, according to the following views: [Physical Education.] In order that man may possess a vigorous frame of body, and its concomitant sound health, without which every species of moral and intellectual excellence is cramped and frustrated, he must be subjected from the moment of birth to such processes of management, and afterwards trained to such habits in food, exercise, cleanliness, and exposure to air, as have been ascertained to conduce to strength and health. [Moral Education.] For the sake of himself and society, he must be habituated, from the dawn of consciousness and feeling, to the regulation of the inferior sentiments of his nature, and gradually to the due exercise of the higher sentiments-justice, kindness, and truth, towards his fellowbeings, and veneration towards the objects of his religious faith. [Intellectual Education.] That he may be qualified for the ready acquisition of knowledge, and the performance of the duties and labours of life, he must be instructed in (1) Reading, at least in his own tongue, (2) Writing, (3) Arithmetic, and (4) Grammar and Composition. That he may enter life with a mind informed respecting that creation of which he is a part, and that society of which he is a member, and qualified, as well as may be, to perform the part which will fall to his lot, he must be acquainted with at least the elements of the following kinds of knowledge (1) the Surface of the Earth (Geography); (2) the Structure of the Earth (Geology); (3) the Vegetable Productions of the Earth (Botany); (4) the Animal Creatures of the Earth (Zoology); (5) the Phenomena of the Atmosphere (Meteorology); (6) the Elements of Matter and their Combinations (Chemistry); (7) the Mechanical Powers and Relations of the Material World (Natural Philosophy); (8) the Science of Measurement (Geometry); (9) the Relation of our Globe to the other component parts of the vast System of Creation (Astronomy); (10) the Physical, Moral, and Intellectual Nature of Man, with reference to the preservation of health, and the attainment of happiness; 11) the Production and Distribution of National Wealth (Political Economy); (12) the History of Nations and Countries, Ancient and Modern, especially those in which the Pupil is most interested-of their Literature, Eminent Men, Resources, &c. As it is not, in the meantime, possible for nearly the whole of the people to acquire a complete intellectual education under masters, the volumes referring to that department will be calculated as much as possible for the use of uninstructed persons all kinds, and in all circumstances.
