Thb design of the preseni work it to offer a condensed and metbodloal CT reatiie on that important department of Natural Philosophy which iom0 pri e9 the diversified phenomena of Eiectricity and Magnetism Theie phenomena, which were formerly regarded aa tbeeffecta of two perfectly distinct agents, are now discovered to have an intimate relation to one another, and, in all probability, to be dependent on one and the same principle :in like manner as it was found by Newton, that the eimpler mechanical phenomena of the universe are the results of the tingle principle of gravitation. A succinct and connected account of the numerous discoveries which the exertions of philosophers have recently brought to light on this highly interesting branch of physical science, collected from the various scientific Journals and Transactions through which they are dispersed, and }digested in a didactic order, seemed to be particularly wanting, and to be especially calculated to further the objects of theS ociety for theD iffusion fof Useful Knowledge. In pursuance of this design, I have aimed at giving to the subjects treated as much condensation as was compatible with perN spicuity. I have endeavoured to conduct the student, by a regular progres sion, from the simpler to the more complex topics of research; and I have also been anxious, by placing constantly before his view the distinction which exists between ascertained facts, and the hypotheses and theories devised for their explanation, to illustrate the precepts of Bacon by examples, and to foster that genuine spirit of philosophical inquiry by which alone error can be avoided and truth attained. For the many deficiencies which I fear the reader will discover in the completion of this design, I have to plead, in extenuation, the very scanty portion of leisure which the continual pressure of my professional duties leaves a(Typographical errors above are due to OCR software and don't occur in the book.)

Excerpt from Treatises on Electricity, Galvanism, Magnetism, and Electro-MagnetismFor the many deficiencies which I fear the reader will discover in the completion of this design, I have to plead, in extenuation, the very scanty portion of leisure which the continual pressure of my professional duties leaves at my disposal. When I undertook this task, at the request of the Society, above four years ago, I was far from anticipating the extent of the labour it has imposed upon me; and from the multiplied interruptions to which I have been subject, I have been compelled to prosecute the work in a desultory manner, and at irregular and uncertain intervals.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Two plates of very soft iron must next be provided, equal in breadth to the surfaces containing the poles, and a little longer than those surfaces; so that, when applied to them, a portion of each plate shall project beyond the loadstone to a small extent. In fig. 58, Rr represents the sections of these iron plates affixed to the opposite sides of the loadstone L; and P p the projecting pieces. These projecting pieces should be much narrower than the other portion of the plates. For loadstones weighing less than an outice, the lower surfaces of the projections need not exceed the tenth of an inch; and so in proportion for larger loadstones. The thickness of the plates, also, must be regulated by the strength of the loadstone, and can scarcely be determined without previous trial in each particular case. The best way, therefore, is to make them tolerably thick at first; and then file off successive layers, until we And, by actual experiment on the power of the loadstone after each reduction, that we cease to obtain any advantage; for the power increases gradually to a certain limit, at which the filing ought to be discontinued. The armature of a loadstone should be fixed on it very firmly, by wires, or by an external case, which should be made of any metal which is not susceptible of magnetism. Loadstones are sometimes cut into a spherical shape, in imitation of the earth, and are then called terrellar. Their armatures should, in that case, be adapted to the curvature of the surface, and should each cover about a quarter of that surface. (216.) The addition of armatures to a loadstone is found to have a very favourable effect in augmenting its strength, and this increase of strength goes on for a considerable time after they have been appli...

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
