Abstract
THIS book, consisting of ten plates and sixty diagrams and descriptive text, is put forward by the author as a contribution to the answers to the questions, What is electricity? and What is magnetism? The diagrams consist of figures representing the lines of force due to various distributions of electricity or magnetism; but in no case is there any quantitative representation attempted. All that we are given is a distribution of arrow heads representing the direction of the ether strains on a molecule. The diagrams being purely qualitative, there is really nothing in the book that a student could not put down himself easily, and frequently with greater accuracy than the author. The conception of lines and tubes of force as treated by Maxwell and Thomson can be most useful and instructive, but as they are given in the present book they can only result in confusion. We are afraid the questions What is electricity? and What is magnetism? are no more nearly answered after the appearance of this book than before.
