An Account of the Extraordinary Medicinal Fluid, called Aether.

The pamphlet explains a chemically prepared ethereal oil produced by decomposing vinous spirit with mineral acids, distinguishes marine, nitrous, and vitriolic varieties, and lists striking physical properties such as extreme lightness, volatility, inflammability, strong solvent action, a pronounced cooling effect, and an unusual affinity for gold. It presents the proponent's medical claims, reporting use against nervous and respiratory disorders—fits, headaches, gout, rheumatism, asthma, whooping cough, pleuritic pains, deafness, and windy stomach ailments—and supplies practical directions for internal dosing, external application, and identifying genuine versus spurious preparations.
