This is a text-book for amateurs, students, and others who want to take up a systematic course of electrical experiments at home or in school. It will give a practical and experimental knowledge of elementary electricity, and thoroughly prepare students for advanced work. Full directions are given for

TWO HUNDRED EXPERIMENTS.

The experiments and discussions are so planned that the student is always prepared for what follows. Although the experiments may be performed with the apparatus that is usually found in school laboratories, the author has designed a complete set of apparatus for those who want to have their own outfit.


If you want to take up a systematic course of experiments—experiments that will build a lasting foundation for your electrical knowledge—this book will serve as a valuable guide.
