An Account of the Extraordinary Medicinal Fluid, called Aether.

Presented as a rare glimpse into eighteenth‑century chemistry, this short treatise introduces a mysterious liquid the author calls “Aether.” Drawing on the work of figures such as Newton and Boyle, the writer explains how the fluid is produced by decomposing wine spirit with vitriolic acid, yielding a substance that is lighter than water, highly volatile, and instantly flammable. The description emphasizes its uncanny ability to float on spirits, to repel heat from a candle, and to chill the touch, setting the stage for its alleged therapeutic potential.

Beyond its spectacular physical traits, the author details Aether’s remarkable chemical interactions, notably its affinity for gold, allowing the metal to remain dissolved in a yellow‑tinged solution that can be separated by simple decantation. He also records its effect on thermometers, where mercury or spirit sinks dramatically, a behavior not seen with ordinary liquids. The work concludes by asserting that repeated experience has shown the fluid to be an effective remedy for nervous disorders, inviting readers to examine the experimental evidence and consider its place in the materia medica.
