Fevers accompanied with an erysipelatous affection about the viscera, may be known by the vehement effervescence and violent pain in the part, also, by the thirst and inordinate burning; in a word, by the symptoms of very acrid bile putrefied along with a deficient blood. They are to be treated in this manner: the patient must abstain altogether from the bath, and at the acme of the complaint, use very cold water in the most decided manner. Yet it must not be used at the commencement, but cold things are to be applied externally; and if this is not sufficient, they must be taken internally. Lettuces and such like things are particularly befitting. The juice of the lettuce is likewise a seasonable application externally, also, that of the house-leek (_semper-vivum_), and such like cooling things. We may use the following application, which is an excellent one: Squeezing out the juice of some cooling thing, we put it into a mortar with purslain, then pound and strain it; at the time of using, we mix a little polenta with it, and place it in cold water to cool it. A piece of cloth folded double is to be put into it, and afterwards applied to the hypochondrium, and not suffered to remain, but another cold one must be substituted. We sometimes mix the oil of unripe olives. * * * * * COMMENTARY. This section is mostly taken from Oribasius, (Synops. vi, 20.) On erysipelas of the lungs consult Hippocrates, (De Morbis, i, 13, and ii, 53.) Hippocrates says in one of his aphorisms (vi, 25), that it is dangerous when an external erysipelas is determined internally, but favorable when an internal erysipelas is determined externally. He describes an epidemical erysipelas which was attended with extensive gangrene of the limbs, but did not often prove fatal. (Epid. i.) The following are the symptoms of fever connected with erysipelatous inflammation, as detailed by Alexander: The patient experiences thirst more strikingly than in any other case, throws the clothes off his body, has exacerbations every third day, with bilious and ichorous discharges from the bowels; those in whom the erysipelatous inflammation is seated in the lungs have not so intense thirst, but breathe thick and large, their cheeks are red, tongue rough, they are delirious, and long rather for cool air, and are more benefited by it than by cool drink, which ought rather to be given to those who have erysipelatous inflammation in any other part, whereas those in whom the lungs are affected ought to be supplied with cool air. In ordinary cases he approves of giving cold water to extinguish the fever, but says that he has seen patients brought to imminent danger by the unseasonable application of cold cataplasms and clysters. Aëtius states that fevers are kindled by the parts about the bowels, liver, and lungs, being attacked with erysipelas. Like our author, he approves of cold drink, cool air, and cold applications to the part affected. (v, 88.)
