Description: "The coils of wire may begin near one pole of the magnet and terminate near the other, or the wire may consist of shorter pieces wound over each other, on any part of the magnet. In either case, the ends of the wire, where several pieces are used, must be soldered to two strips of tinned sheet copper, for the combined positive and negative poles of the wires. To form the magnet, these pieces of copper are made to commnicate with the poles of the battery, by means of cups containing mercury, as shown in the figure, or by any other method." —Comstock, 1850
