mour; particularly, thick gruels, food made of unground wheat, with honey and water, or a great quantity of wine and milk.
Lean, bilious, hot, and dry bodies are more inclinable to the measles, than to the small-pox. But if they happen to be taken with the small-pox, the pustules are either few, distinct, and favourable; or, on the contrary, very bad, irregular, deceitful, dry, with putrefaction, and no maturation.
Lastly, thin, and dry bodies, of a cold temperament, are neither subject to the fmall-pox, nor to the measles. And if they happen to catch the small-pox, they have but few, in a moderate way, and without danger, with a very slight fever ; because such conftitutions extinguish the disease in its very beginning.
The seasons of the year in which the small-pox are most frequent, are various ; they rage most at the latter end of the autumn, and the beginning of the spring : and when in the summer there are great and frequent rains, with continual fouth-winds ; and lastly, when the winter is warm, and the winds southerly.
When the summer is excessively hot and dry, and succeeded by a hot autumn, in which rains come on very late ; then the measles quickly seize those who are disposed to them, that is, those who are lean, hot, and of bilious constitutions.
But all these things admit of great differences, by reason of the diversity of countries and places, and occult dispositions in the air, which bring on those diftempers, and render bodies subject to them. And therefore, at such times great diligence is to be used
in the preservation from them; as we shall shew in the sequel.
с н А Р. III. Of the prognostic signs of the eruption of the small
pox and measles.
THE eruption of the finall-pox is preceded by a continual fever, a pain in the back, itching
in the nose, and terrours in Neep. These are the proper signs of the approaching small-pox, especially the pain in the back, with a fever ; and also a pricking, which the patient feels all over his body ; together with a fulness and redness of the face, which at times goes and comes :
a redness of the eyes, a heaviness of the whole body ; frequent yawnings, a pain in the throat and breast, with a difficulty in breathing, and straitness in the gullet, then a driness of the mouth, thick fpittle, a hoarseness of the voice ; head-ach, anxiety of mind, inquietude ; fick qualms and heaviness of heart: with this difference, that anxiety of mind, fick qualms, and heaviness of heart, oppress more in the ineasles than in the finall-pox, unless the fmall. pox be of a bad fort; for the measles are from a very bilious blood. And, on the other hand, the pain in the back, the heat and inflammation of the whole body, especially in the throat, with a shining redness, are more proper to the small-pox than to the measles.
Wherefore, upon the appearance of these figns, or fome of the worst of them, you may be assured, that one or the other of these diseases is nigh at hand,
As to the fafer kind of the small-pox ; in these, the quantity of blood is greater than its bad quality; and hence arises the pain of the back; the greater blood-vessels, which are situated near the vertebræ of the back, being distended with too great a quantity of blood.
Of the regimen, or cure of the small-pox in general.
HE first article shall be of the preservation to
pear; and after they have appeared, how the diseafe may be lessened.
The second, concerning the eruption,
The third, the care to be taken of the eyes, ears, nose, throat, and joints.
The fourth, of the ripening of the pustules.
The fixth, how the scales and crusts are to be cleared from the eyes, and the rest of the body.
The seventh, of destroying the marks.
The ninth, of regulating the discharge by the intestines.
The tenth, of curable and incurable small-pox and measles.
Of each of these I shall, God willing, briefly, but sufficiently discourse.

Of freservation from, and lefening the disease.
Lood ought to be taken away from children and
young men, if they liave never had the smallpox, or have only had what is called the chicken-pox, (especially at such feafons as we have above described), before they are feized with a fever, and the signs of the disease appear.
A vein may be opened in those who are fourteen years old'; to those who are younger, cupping glasses must be applied, and their lodgings should be kept cool.
Let their diet be yellow lentils, tarts made of unripe grapes, minced Aem-meat, dressed with vinegar and honey, or with the acid fyrup; to which' raisins, a few figs, and chiches 'are sometimes added : alfo kid-broth, veal-jellies, and boiled woodcocks and hens. But there must be mixed with the juice of unripe grapes.
Their drink should be water cooled with snow, or clear spring-water cold; with which their chamber may also be sprinkled.
Let them frequently eat acid pomegranates, and the inspissated juices of acid and 'astringent fruits, as pomegranates, currants *, and the like.
Where the constitution is hot, and there is a great inflammation ; barley-water, with a fourth part of acid pomegranate juice, may be drank in the morning.
* The Arabic word is Ritas, which also signifies ? fort of lapathum acetosum, or forrel, of which the red and acid juice boiled to two thirds, is called Rub de Ribes. See Golii lexic,
But if the heat be lefs, a ptifan of barley, with fu-
pestilence; for it diminishes the malignity of pestilential ulcers, and boils ; and prevents quinseys, pleurisies; and all distempers arising from bile and blood.
The patient may go into cold water, and swim in it about noon. He must abstain from new milk, wine, dates, honey, and, in general, from swees things, and meats made by a mixture of felh, onions, oil, butter, and cheefe ; from mutton, beef, fhell.fish, high-feasoned things, and hot feeds. In: stead of these, in times of contagion, he may eat young birds : and if the temperament be hot and moist, liable to putrefaction, or hot and dry, and apt to be inflamed; he must eat as follows ; that is, in the hot and dry constitution, cooling and moist garden-herbs, purNain, mallows, beet, gourds, cucumbers, forrel,, and small pompions.
As to sweet melons, they are forbidden ; and if any one by chance eats of them, he must presently drink a spoonful of the juice of fome of the acid fruits. He may be allowed foft fish, and butter-milk.
To the food of those who are corpulent, fleshy, and of a rudy complexion, such cooling and drying things, as we have mentioned, may be added. They should all forbear labour, fatigue, bathing, venery, walking or riding in the fun and dust, drinking of stagnating waters, blasted fruits, or mouldy herbs ; and also figs and grapes : because these drive the hu
