In selecting the apparatus for the experiments in thisbook, the author has kept constantly in mind the factthat the average student will not buy the expensivepieces usually described in text-books.
The two hundred experiments given can be performedwith simple, inexpensive apparatus; in fact, the studentshould make at least a part of his own apparatus.
For the benefit of those who wish to make their ownapparatus, the author has given, throughout the work,explanations that will aid in the construction of certainpieces especially adapted to these experiments. Forthose who have the author's "How Two Boys MadeTheir Own Electrical Apparatus," constant referenceshave been made to it as the "App
