"If you please to pour one part of _Sal volatile oleosum_, or any other oily salts into a narrow-bottomed wine-glass, and near the like quantity of Stringer's Elixir, _febrifugium martis_, there will be a pleasant conflict: the elixir will immediately make a preparation of and precipitate those oily volatile salts into a fixed armoniac salt in the bottom, and receive the spirituous aromatic oily parts into itself, and yet retain its own virtues, colour, and taste. There is no other true and genuine elixir but Mr. Stringer's that is exposed to sale; for those called _Elixir proprietatu_ and _Elixir salutis_, &c. are mere tinctures drawn by brandy or nasty spirits; but this is a perfect elixir or quintessence, whose perfect principles of spirits, oil, and salt, are so inseparably united, that it can neither decay, putrefy, nor die, _no more than the glass that contains it_; and is so far from being a harsh corrosive, that it feels like oil, yet dries like a spirit, cleanses the skin like soap, and not only allays all putrefactive ferments in a moment, _but immediately cures the most malignant fevers_, takes away all _sorts of corns and hardness_ in the skin, and makes the roughest hands smooth and white, only by anointing with it morning and night for a month together: which medicine with his other called Salt of Lemons, _in despite of all opposers_, will approve themselves nearest of affinity to an _universal medicine_." In this admirable medicine the Londoner of 1700 had an internal and an external application, and materials to cleanse and soften the hands, which would at the same time enable him to walk the streets in comfort and ease, in defiance of corns and _horny_ excrescences. Happy Londoners! possessing such men as Dr. Pechey and Mr. Stringer, aided by Dr. Case, whose _unguentum panchrestum_, prepared by the _Spagyrick art_, might justly be called the _Golden Mine_. This wonderful preparation cured by its _sympathetical_ powers; in short, the Doctor found "it more infallible than the _Zenexton_ of _Paracelsus_." This great Doctor was the means of informing us that Quacks were then in the habit of employing persons to thrust bills into the hands of passengers in the streets. For example: "Your old friend, Dr. Case, desires you not to forget him, although he has left the _common way of bills_." A _brother Quack_ this year issued the following notice: "John Poley, at Broken-wharf, over-against the Water-mill in Thames-street, next door to the Bell, will undertake to cure any smokey chimneys. _No cure, no money._"
