   1. The loadstone; a species of iron ore (the ferrosoferric or
      magnetic ore, {Fe3O4}) which has the property of
      attracting iron and some of its ores, and, when freely
      suspended, of pointing to the poles; -- called also
      {natural magnet}.

      peculiar properties of the loadstone have been imparted;

         voltaic or electrical battery, is called an
