Sec. 246. The Duration and _Crisis_ of these malignant, as well as those of putrid Fevers, are very irregular. Sometimes the Sick die on the seventh or eighth Day, more commonly between the twelfth and the fifteenth, and not infrequently at the End of five or six Weeks. These different Durations result from the different Degree and Strength of the Disease. Some of these Fevers at their first Invasion are very slow; and during a few of the first Days, the Patient, though very weak, and with a very different Look and Manner, scarcely thinks himself sick. The Term or Period of the Cure or the Recovery, is as uncertain as that of Death in this Distemper. Some are out of Danger at the End of fifteen Days, and even sooner; others not before the Expiration of several Weeks. The Signs which portend a Recovery are, a little more Strength in the Pulse; a more concocted Urine; less Dejection and Discouragement; a less confused Brain; an equal kindly Heat; a pretty warm or hot Sweat in a moderate Quantity, without Inquietude or Anguish; the Revival of the different Senses that were extinguished, or greatly suspended in the Progress of the Disease; though the Deafness is not a very threatening Symptom, if the others amend while it endures. This Malady commonly leaves the Patient in a very weak Condition; and a long Interval will ensue between the End of it, and their recovering their full Strength. Sec. 247. It is, in the first place, of greater Importance in this Distemper than in any other, both for the Benefit of the Patients, and those who attend them, that the Air should be renewed and purified. Vinegar should often be evaporated from a hot Tile or Iron in the Chamber, and one Window kept almost constantly open. 2, The Diet should be light; and the Juice of Sorrel may be mixed with their Water; the Juice of Lemons may be added to Soups prepared from different Grains and Pulse; the Patient may eat sharp acid Fruits, such as tart juicy [65] Cherries, Gooseberries, small black Cherries; and those who can afford them, may be allowed Lemons, Oranges and Pomgranates. [65] The French Word is _Griettes_, which _Beyer_ englishes, _the Agriot, the red or sour Cherry_; and _Chambaud, the sweeter large black Cherry or Mazzard_--But as Dr. _Tissot_ was recommending the Use of Acids, it is more probably the first of these: so that our Morellas, which make a pleasant Preserve, may be a good Substitute to them, supposing them not to be the same. Our Berbery Jam, and Jelly of Red Currants, may be also employed to answer the same Indication. _K._ 3, The Patient's Linen should be changed every two Days. 4, Bleeding is very rarely necessary, or even proper, in this Fever; the Exceptions to which are very few, and cannot be thoroughly ascertained, as fit and proper Exceptions to the Omission of Bleeding, without a Physician, or some other very skilful Person's seeing the Patient.
