"An Essay to Shew the Cause of Electricity; and Why Some Things are Non-…", written by John Freke, is a scientific publication from the mid-18th century. In this work, Freke explores the phenomenon of electricity, articulating his theories about its causes, effects, and the nature of materials that can or cannot conduct electricity. The treatise is notable for addressing the relationship between electricity and natural elements, as well as its impacts on living organisms and the environment. In his essay, Freke posits that electricity arises from "universal Fire" dispersed in the air, arguing against the notion that it originates solely from the apparatus used in experiments. He discusses various aspects of electricity, including how it can cause certain materials to become electrified and the implications of non-electricable substances like silk and wax. Freke also connects electricity to broader concepts in nature, such as the vitality of living organisms and the effects of air quality on human health. Through experiments and observations, he endeavors to offer explanations for electrical phenomena, aiming to illuminate understanding of this mysterious force that was not well comprehended at the time.
