Bennet published
New Experiments on Electricity in 1789. In it, he described: • The gold-leaf electroscope; • A
doubler of electricity, already announced in a paper communicated to the
Royal Society by Rev.
Richard Kaye FRS,
Dean of Lincoln in 1787; and • A theory of electricity that anticipated Volta's
contact theory. Bennet's work was a key element in leading Volta to the contact theory and the development of the
voltaic pile. Bennet described experiments with an
electrophorus and the generation of electricity by
evaporation. Bennet extended his thinking into various theories about electricity and weather, with electrical explanations of the
aurora borealis and
meteors. He interpreted
lightning as the release of
electrical charge from clouds, and went on to hypothesise that rain was caused by lightning and also that
earthquakes had an electrical origin. File:Bennet-2.jpg|alt=Spine of a 1789 copy of Bennet's New Experiments, with title written in gold script|1789 edition of
