It has supplied us with power, light, and the means of instantaneous communication. Of course the mysterious forces and possib...ilities of electricity had been guessed at long before. The ancients knew of electricity mainly as a result of friction, such as that obtained by the rubbing of a piece of amber. The discoveries of Galvani and later of Volta at the close of the eighteenth century opened up a new era in the history of science, and were the first experiments that led to such wonderful practical results. Volta's invention, the electric " pile " or " crown of cups, " was the embryo of the modern electric battery. Another stage in the development of the science came early in the nineteenth century when Oersted, a Dane, established the connexion between electricity and magnetism.
