Experiments and Observations Tending to Illustrate the Nature and Properties of Electricity / In One Letter to Martin Folkes, Esq; President, and Two to the Royal Society

Like that extraordinary Power likewise, it exerts its Force in Vacuo as powerfully as in open Air, and this Force is extended to a considerable Distance through various Substances of different Textures and Densities.
