A Treatise on Electricity Wherein its various phænomena are accounted for, and the cause of the attraction and gravitation of solids, assigned. To which is added, a short account, how the electrical effluvia act upon the animal frame, and in what disorders the same may probably be applied with success, and in what not.

An 18th-century surgeon explores the electrifying possibilities of how electricity can be used to heal, while also trying to explain the origins of gravity.
