About this book
How Two Boys Made Their Own Electrical Apparatus, by Thomas M. St. John, contains complete directions for making all kinds of simple apparatus for the study of elementary electricity. The contents list a chapter titled Cells and Batteries. The text says that when two or more cells are joined together the combination is called a battery. The text describes the gravity cell as really a two-fluid cell in which the two liquids are kept separate by the joint action of the current and the force of gravity.
The text gives directions for a tangent galvanometer, saying the base consists of 2 parts, A and B. The text says to get the true reading, take the average of the two, which in the case mentioned would be 22 degrees.
