Abstract
THE author has provided, at a moderate price, a very useful little book, which should do much to encourage the beginner to construct simple electrical apparatus with which to make a number of instructive experiments. The book is illus trated with a number of photographs of the apparatus described, which the author has himself constructed. In addition, there are good work ing drawings and diagrams of connections where these are helpful. The real utility and educa tional value of work of this kind to the beginner cannot be insisted upon too often. He has read of and perhaps seen professionally made appa ratus, and he naturally supposes that nothing within his constructive power can be any good, and more especially is this the case if he is not already fairly accomplished in the use of tools. While his earlier efforts may not be much use to anybody else they are of immense value to him—that is, if he has any perseverance. He may gradually come to learn that rough-looking appa ratus may really work up to a point well, and so begin to acquire that confidence in himself which is essential when, at a later stage, he has original ideas. He may then either make preliminary rough experiments to see if, with better work, they promise to succeed, or if he has become a good manipulator he may have discovered that he can carry out his own ideas quickly and with sufficiently good work in the essential parts to get better results than he could hope for if he depended entirely upon others to put his ideas into form.
