There is but one known Medicine that can effectually oppose this Sort, which is the Bark, given as directed Sec. 260. Nothing affords Relief in the Fit, and no other Medicine ever suspends or puts it off. But I have cured some of these Disorders with the Bark, and especially those affecting the Eyes, which happen oftner than the other Symptoms, after their Duration for many Weeks, and after the ineffectual Use of Bleeding, Purging, Baths, Waters, Blisters, and a great Number of other Medicines. If a sufficient Dose of it be given, the next Fit is very mild; the second is prevented; and I never saw a Relapse in these Cases, which sometimes happens after the Fits of common Intermittents seemed cured. Sec. 272. In Situations where the Constitution of the Air renders these Fevers very common, the Inhabitants should frequently burn in their Rooms, at least in their lodging Rooms, some aromatic Wood or Herbs. They should daily chew some Juniper Berries, and drink a fermented Infusion of them. These two Remedies are very effectual to fortify the weakest Stomachs, to prevent Obstructions, and to promote Perspiration. And as these are the Causes which prolong these Fevers the most obstinately; nothing is a more certain Preservation from them than these cheap and obvious Assistances. [70] [70] I have seen several Cases in very marshy maritime Countries, with little good drinking Water, and far South of _Swisserland_, where intermitting Fevers, with Agues at different Intervals, are annually endemic, very popular, and often so obstinate as to return repeatedly, whenever the weekly precautionary Doses of the Bark have been omitted (through the Patient's nauseating the frequent Swallowing of it) so that the Disease has sometimes been extended beyond the Term of a full Year, and even far into a second, including the temporary Removals of it by the Bark. Nevertheless, in some such obstinate Intermittents, and particularly Quartans there, wherein the Bark alone has had but a short and imperfect Effect, I have known the following Composition, after a good Vomit, attended with speedy and final Success, _viz._ Take of fresh Sassafras Bark, of Virginia Snake-root, of Roch-Allom, of Nutmeg, of diaphoretic Antimony, and of Salt of Wormwood of each one Drachm. To these well rubbed together into fine Powder, add the Weight of the whole, of the best and freshest Bark; then drop in three Drops of the chemical Oil of Mint, and with Syrup of Cloves make it into the Consistence of an Electuary or Bolus, for 12 Doses for a grown Person, to be taken at the Distance of three or four Hours from each other, while the Patient is awake, according to the longer or shorter Intermission of the Fever.
