The distemper is equally known, which is called sometimes arquatus(39), sometimes regius. If this comes on after the seventh day of a fever, Hippocrates pronounces the patient to be safe, provided only the præcordia be soft. Diocles declares without reserve, that if it comes after a fever, it even does good; if a fever follows it, it is mortal. Now this distemper is discovered by the colour, especially of the eyes, in which, what ought to be white, becomes yellow. And it is generally attended by a thirst, pain of the head, frequent hiccough, hardness of the præcordia on the right side; and upon violent motion, a difficulty of breathing, and relaxation of the limbs: and when the distemper continues long, the whole body turns white, with a certain sickly paleness.

For the first day it is proper to enjoin the patient to abstinence; on the second to give a clyster; then if there is a fever, to remove it by proper diet; if there is not, to give scammony to drink, or white betes shred in water, or in hydromel bitter almonds, wormwood, anise, but of the last the smallest quantity. Asclepiades ordered also the drinking of salt water, and that for two days, with an intention to purge, rejecting the use of diuretics. Some omitting the former, by the latter and extenuating diet affirm they obtain the same purpose.

For my part if there be sufficient strength, I prefer the stronger medicines; if but little, the weaker remedies. If the patient has been purged, after that it is fit for the three first days to eat sparingly food of the middle kind, and drink Greek salt wine, that the belly may continue lax; then for other three days to eat more substantial food and some flesh too; and hold to the use of water for drink; then to return to the former diet, only eating more freely of it; and omitting the Greek, to drink black austere wine; and vary this course by using sometimes acrid food, sometimes returning to the salt wine. But through the whole time exercise and friction must be used, and if it be winter, the bath, if summer, swimming in cold water; a bed and room elegant, company, place, diversions, frolicks, and every thing else, that has a tendency to exhilarate the mind: upon which accounts it seems to be called the royal distemper. A discutient malgama also applied to the præcordia has a good effect; or a dry fig laid on there, if the liver or spleen be affected.
