The immediate outcome of the issue of theS yllabus of theD epartmental Examination, which candidates for superior appointments were required to pass before they could take up such appointments, was a demand for a more popular exposition of the first principles of Electricity, and a more detailed application of these principles toT echnical Telegraphy than had hitherto been available, even in the best text-books on the subject. The student who had not laboriously followed a course of study in the science which found its practical application inT elegraphy was placed at some disadvantage in commencing to read a technical textbook in which the fundamental facts of the science were taken for granted ;and, so far as could be ascertained, no text-book had been published which filled the gap between the purely scientific text-book dealing with general laws and principles, on the one hand, and, on the other, a technical text-book dealing with the details of an industry in which these laws were applied, and in which the fundamental scientific facts were assumed. The writer of the present volume was, therefore, requested by theE ditor of the Telegraph Chronicle to undertake a series of papers, in which the steps between the scientific text-book and the technical textbook should be dearly defined and traced in such a way that the initial difficulties in studying the latter might be disposed of, and which at the same time should tae into their purview the whole of the ground covered by theD epartmental Syllabus. The papers were undertaken at short notice, and little time was allowed for elaboration. Yet in spite of the crude form in which the facts were expressed the papers proved to have fulfilled their design, and to have supplied a long-felt want in so complete a manner that, in response to a widely expressed desire that somepermanentform might be given to the articl
