Electricity, n. The power that causes all natural phenomena not known to be caused by something else. Electricity seems destined to play a most important part in the arts and industry. The question of its economical application to some purpose is still unsettled, but experiment has already proved that it will propel a street car better than a gas jet and give more light than a horse. - Ambrose Bierce (from The Devil's Dictionary)
