Excerpt from The Elements of Dynamic Electricity and Magnetism
On important controverted points the leading views on both sides have been given; and the selections of practical, electric appliances for description have been made with strict reference to the adaptation of each to illustrate some important principle to the best advan~ tage. Clearness of style has been recognized as a first requisite, and conciseness as subordinate to it.

Excerpt from The Elements of Dynamic Electricity and Magnetism
This book was written for learners rather than for the learned. Previous to the last decade the demand for electric books was confined chiefly to scientific investigators versed in the higher mathematics, and the authors of such books were electricians of the same class, who recognized the importance of mathematical accuracy in treating electric phenomena. Hence mathematical formulaæ became a prominent feature of such books. But the various electric industries to which the recent unprecedented electric development has given rise, have given employment to a numerous class of persons to whom mathematical books are almost unintelligible, and yet to whom a scientific knowledge of the various kinds of electric apparatus which they are required to operate, or with which their business is connected, is of the highest importance. There is also a class of liberally educated persons who desire to extend their knowledge of electric principles, but have not the time or patience to follow the intricacies of mathematical formulaæ, especially in the abbreviated form usual in the books referred to.
