Sec. 264. The Patient ought, two Hours before the Invasion of the Fit, to drink a small Glass of warm Elder Flower Tea, sweetened with Honey, every Quarter of an Hour, and to walk about moderately; this disposes him to a very gentle Sweat, and thence renders the ensuing Coldness and the whole Fit milder. He is to continue the same Drink throughout the Duration of the cold Fit; and when the hot one approaches, he may either continue the same, or substitute that of No. 2, which is more cooling. It is not necessary however, in this State, to drink it warm, it is sufficient that it be not over cold. When the Sweat, at the Termination of the hot Fit, is concluded, the Patient should be well wiped and dried, and may get up. If the Fit was very long, he may be allowed a little Gruel, or some other such Nourishment during the Sweat. Sec. 265. Sometimes the first, and a few successive Doses of the Bark purge the Patient. This is no otherwise an ill Consequence, than by its retarding the Cure; since, when it purges, it does not commonly prevent the Return of the Fever; so that these Doses may be considered as to no Purpose, and others should be repeated, which, ceasing to purge, do prevent it. Should the Looseness notwithstanding continue, the Bark must be discontinued for one entire Day, in order to give the Patient half a Quarter of an Ounce of Rhubarb: after which the Bark is to be resumed again, and if the Looseness still perseveres, fifteen Grains of Venice Treacle should be added to each Dose, but not otherwise. All other Medicines which are superadded, very generally serve only to increase the Bulk of the Dose, while they lessen its Virtue. Sec. 266. Before our thorough Experience of the Bark, other bitter Medicines were used for the same Purpose: these indeed were not destitute of Virtue in such Cases, though they were considerably less available than the Bark. Under No. 43, some valuable Prescriptions of that kind may be seen, whose Efficacy I have often experienced: though at other Times I have been obliged to leave them off, and recur to the Bark more successfully. Filings of Iron, which enter into the third Prescription, are an excellent Febrifuge in particular Cases and Circumstances. In the Middle of the Winter 1753, I cured a Patient of a Quartan Ague with it, who would not be prevailed on to take the Bark. It must be confessed he was perfectly regular in observing the _Regimen_ directed for him; and that, during the most rigid Severity of the Winter, he got every Day on Horseback, and took such a Degree of other Exercise in the open Air, as disposed him to perspire abundantly.
