The galvanic pile employed in this electroscope is that invented by Zamboni.

A small ball of gold gives off a great deal of vapor if placed between two carbon points and subjected to the action of a powerful galvanic pile.

By heat and by decomposition; the tourmalin; cats; galvanic pile; evaporation of water.

A series of simple experiments now embarked upon showed the behaviour of magnetised iron, as also of a galvanic pile or battery, to remain unaltered.

Galvani, the discoverer of animal electricity, and Volta, the inventor of the galvanic pile, stimulated others to fruitful experiments in this branch of study.
