It is common also for a coldness to precede fevers, which of itself is a very troublesome kind of disorder. When it is expected, the patient must be forbid all drink: for giving this a little before much increases the malady. He is also to be timely covered with many cloaths. Dry and hot fomentations are to be used to those parts, for which we are apprehensive; in such a manner that the most violent heat may not begin immediately, but increase gradually. And those parts are to be rubbed with the hands anointed with old oil, and some of the warming medicines may be added to it. And some physicians are content with one friction with any kind of oil. In the remissions of such fevers some give three or four cyathi of gruel, while the fever still continues; and then, when it is quite over, refresh the stomach with cold and light food. I think this ought to be then tried, when food once given, and that after the fever, does little service. But great care must be taken, that we be not deceived as to the time of the remission; for even in this kind of distemper, often the fever seems to abate, and again increases. Wherefore we must trust no remission, but that, which both continues, and lessens the restlessness, and excessive heat of the body, which the Greeks call(11) zesis[BD]. This is a rule generally received, if every day the fits are equal, to give a little food every day: if unequal, food must be given after the most severe; after the milder hydromel. [BD] ζίσις. CHAP. XII. THE CURE OF A SHUDDERING BEFORE FEVERS. A shuddering commonly precedes those fevers, that have a certain period, and a perfect remission, and for this reason are the most safe, and most easily admit of a cure: for where the periods are uncertain, neither clysters, nor the bath, nor wine, nor any other remedy can be duly administered. For it is uncertain when the fit will come: so that if it come on suddenly, the greatest detriment may happen to accrue from that, which was intended to give relief. And nothing else can be done, than that the patient practise a strict abstinence in the first days of the disease: then upon the decline of that fit, which is most severe, let him take food.
