Abstract
THIS work is addressed as much to those connected with the electrical industry who are not directly associated with the technical side as to students about to embark upon an electrical career. The subject is looked at from the practical engineering point of view, but shows some departure from conventional lines. The elementary principles of currents and their effects are well set out, and of the later chapters those on the magnetisation of iron, measuring instruments, and insulating materials may be picked out as the best examples of well-selected information arranged with originality. In the last mentioned there is a cood deal not found in the ordinary text-book, including a most useful summary of the composition, preparation, and properties of a number of insulating materials in common use. Another subject not always treated satisfactorily in elementary books is that of the magneto for ignition purposes, of which there is a brief but clear sketch.
