REED & BARBER, OF HARTFORD, HAVE JUST PUBLISHED, A COMMON SCHOOL PHILOSOPHY, BY J. L. COMSTOCK, M. D. The design of which is to afford a facility to the introduction of Natural Philosophy into common schools, which has not heretofore existed in our country. The treatises on this subject, are either too large and expensive for general admission in country schools; or if otherwise, the matter which they contain is not rendered sufficiently simple and attractive for this purpose. The treatise now offered the public, is an attempt to supply this deficiency in the series of American school books. The distinct sciences, the elements of which are here explained, are Mechanics, Hydrostatics, Hydraulics, Pneumatics, Acoustics, Optics, and Electricity; each being illustrated by numerous diagrams, and it is hoped made as plain, and easily understood as the nature of the cases will allow. The propriety and advantage of introducing these subjects as a branch of common education will not, it is believed, be denied by any intelligent teacher; or by any parent who desires that his child may be able to understand and explain, many of the every-day occurrences of life, and the common phenomena of nature. The want of this kind of knowledge is indeed regretted by every intelligent, uneducated person in himself; for such persons every day observe facts, which though mysterious to themselves, they know are readily explained by those who have even but a slight knowledge of Natural Philosophy. Yet, notwithstanding our advancement in the sound principles of education, it is now quite common to see pupils at school, who, though they are able to recite the names of every tributary to the Mississippi; and the succession of every bay from Boston to New Orleans, are still unable to tell the reason why a lever assists in raising a weight;—why a pump draws up the water from a well, or even which way the earth on which they live turns, whether from west to east or east to west.
