9, If the Fever has been clearly off for a long Part of the Day; if the Tongue appears in a good healthy State; if the Patient has been well purged; and yet one moderate Paroxysm of the Fever returns every Day, he should take four Doses of the Powder No. 14 between the End of one Return and the Beginning of the next, and continue this Repetition some Days. People who cannot easily procure this Medicine, may substitute, instead of it, the bitter Decoction No. 37. four Glasses of which may be taken at equal Intervals, between the two Paroxysms or Returns of the Fever. 10, As the Organs of Digestion have been considerably weakened through the Course of this Fever, there is a Necessity for the Patient's conducting himself very prudently and regularly long after it, with Regard both to the Quantity and Quality of his Food. He should also use due Exercise as soon as his Strength will permit, without which he may be liable to fall into some chronical and languishing Disorder, productive of considerable Languor and Weakness. * [*] As our Jail, Hospital, and Camp Fevers may often be ranged in this Class, as of the most putrid Kind, and not seldom occasioned by bad Food, bad Air, unclean, unwholesome Lodging, _&c._ a judicious Use may certainly be made of a small Quantity of genuine, and not ungenerous, Wine in such of them, as are not blended with an inflammatory Cause, or inflammable Constitution, or which do not greatly result from a bilious Cause; though in these last, where there is manifest Lowness and Dejection, perhaps a little Rhenish might be properly interposed between the Lemonade and other Drinks directed Sec. 241. Doubtless Dr. _Tissot_ was perfectly apprized of this salutary Use of it in some low Fevers; but the Necessity of its being regulated by the Presence of a Physician has probably disposed him rather to omit mentioning it, than to leave the Allowance of it to the Discretion of a simple Country Patient, or his ignorant Assistants. _K._ __Chapter XVII.__ _Of malignant Fevers._ __Sect.__ 242. Those Fevers are termed malignant, in which the Danger is more than the Symptoms would make us apprehensive of: they have frequently a fatal Event without appearing so very perilous; on which Account it has been well said of this Fever, that it is a Dog which bites without barking. Sec. 243. The distinguishing _Criterion_ or Mark of malignant Fevers is a total Loss of the Patient's Strength, immediately on their first Attack. They arise from a Corruption of the Humours, which is noxious to the very Source and Principle of Strength, the Impairing or Destruction of which is the Cause of the Feebleness of the Symptoms; by Reason none of the Organs are strong enough to exert an Opposition sufficiently vigorous, to subdue the Cause of the Distemper.
