Excerpt from First Steps in Electricity: Designed for the Entertainment, and Instruction of Young People at Home, and in School
The aim of this book is to describe a number of simple and inexpensive experiments in electricity that can be performed in schools, the lecture-room, and the home circle. None of the experiments are at all difficult or dangerous, nor are the materials, if used with ordinary care, likely to do the slightest harm to furniture or clothing. The aim is also to enable the reader to obtain a general idea of the laws governing the manifestations of this force in nature, and to see how this force is used in the arts, in business, and in manufactures. It is the hope of the author that the book may be of use as a school reader, as a guide to home amusements in science for winter evenings, and as a help to all who wish to get a notion of the general principles underlying the great modern inventions in electricity.
