However, Eeles was confident that electricity was the cause of thunder and lightning. In order to prove this Eeles undertook a number of experiments in the Knockmealdown Mountains. As a result of these trials Eeles penned a number of essays, which he submitted as letters to the Royal Society. [Wikipedia]. N° de ref. del artículo 001617
