Excerpt from Elementary Lessons in Electricity and Magnetism These Lessons in Electricity and Magnetism are in tended to afford to beginners a clear and accurate knowledge of the experiments upon which the Sciences of Electricity and Magnetism are based, and of the exact laws which have been thereby discovered. The difficulties which beginners find in studying many modern text-books arise partly from the very wide range of the subject, and partly from want of famili arity with the simple fundamental experiments. We have, at the outset, three distinct sets of phenomena to observe, viz. - those of Frictional Electricity, of Current Electricity, and of Magnetism; and yet it is impossible to study any one of these rightly without knowing something of them all. Accordingly, the first three Chapters of this work are devoted to a simple exposition of the prominent experimental facts of these three branches of the subject, reserving until the later Chapters the points of connection between them, and such parts of electrical theory as are admissible in a strictly elementary work. N o knowledge of algebra beyond simple equations, or of geometry beyond the first book of Euclid, is assumed.
