Abstract
THIS little work is one of a series designed for use in continuation classes and central schools to form the first stage in specialisation in the direction of electro-technics, and necessarily treats the subject in an elementary way intermediate between the scientific and the practical. With the exception of a brief mention of the transformer, only continuous currents are dealt with, and only the very simplest mathematics are required. The conception of the electric current is very suitably introduced by simple experiments with dry cells, and commendable features of the method by which the subject is developed include the leading up to the permanent magnet through the electro-magnet, and making the student familiar with the effects of a current before he is bothered about details as to its production. On the whole, however, we should have liked to see a little more continuity of idea in the treatment. Practical applications are kept well in view all through, and, in spite of a few minor inaccuracies of engineering detail, form adequate illustrations of the principles. Lamps and lighting, motors and dynamos, and the telephone are briefly explained, and, as might be expected, electrostatics do not come within the purview of the treatment.
