The case of pestilential fevers demands attention and a peculiar treatment. In this it is by no means good to try fasting, or medicines, or clysters. If the strength will admit, it is best to let blood; especially if the fever be attended with a burning heat. If that is not safe, when the fever is either abated, or less violent, to cleanse the breast by a vomit. But there is a necessity to order the bath sooner in this than in other distempers; to give wine strong and hot, and every thing glutinous; amongst which flesh of the same kind. For the more quickly that such constitutions of the air destroy, so much the sooner must remedies be laid hold of, even with a degree of rashness. But if he be a boy, that labours under it, and have not sufficient strength for bleeding, he must be cupped, and have a clyster either of water, or the cream of ptisan; then lastly he is to be nourished by light food. It is a general rule, that boys ought to be treated altogether in a different method from men. Wherefore in this, as well as in every other kind of distemper, greater caution must be used at that age in the following articles: not to bleed, not to give a clyster without necessity, nor to torment by watching, or fasting, or excessive thirst, nor to attempt the cure by wine. The patient must vomit after the fever: then the lightest kind of food is to be given; after that he is to sleep: the day following, if the fever continue, he must fast; on the third day return to the same diet. And we must endeavour, as much as possible in the midst of a seasonable abstinence to nourish him by food at proper times, laying aside every thing else. [Sidenote: _Of an Ardent fever._]
