4. If the Face and Neck are greatly swelled, emollient Cataplasms are to be applied to the Soles of the Feet; and if these should have very little Effect, Sinapisms should be applied. These are a kind of Plaister or Application composed of Yeast, Mustard-flower, and some Vinegar. They sometimes occasion sharp and almost burning Pain, but in Proportion to the Sharpness and Increase of these Pains, the Head and Neck are remarkably relieved. Sec. 215. The Eyelids are puffed up and swelled when the Disease runs high, so as to conceal the Eyes, which are closed up fast for several Days. Nothing further should be attempted, with Respect to this Circumstance, but the frequent moistening of them with a little warm Milk and Water. The Precautions which some take to stroke them with Saffron, a gold Ducat, or Rose-water are equally childish and insignificant. What chiefly conduces to prevent the Redness or Inflammation of the Eyes after the Disease, and in general all its other bad Consequences, is to be content for a considerable Time, with a very moderate Quantity of Food, and particularly to abstain from Flesh and Wine. In the very bad Small Pocks, and in little Children, the Eyes are closed up from the Beginning of the Eruption. Sec. 216. One extremely serviceable Assistance, and which has not been made use of for a long Time past, except as a Means to preserve the Smoothness and Beauty of the Face; but yet which has the greatest Tendency to preserve Life itself, is the Opening of the Pustules, not only upon the Face, but all over the Body. In the first Place, by opening them, the Lodgment or Retention of _Pus_ is prevented, which may be supposed to prevent any Erosion, or eating down, from it; whence Scars, deep Pitts and other Deformities are obviated. Secondly, in giving a Vent to the Poison, the Retreat of it into the Blood is cut off, which removes a principal Cause of the Danger of the Small-Pocks. Thirdly, the Skin is relaxed; the Tumour of the Face and Neck diminish in Proportion to that Relaxation; and thence the Return of the Blood from the Brain is facilitated, which must prove a great Advantage. The Pustules should be opened every where, successively as they ripen. The precise Time of doing it is when they are entirely white; when they just begin to turn but a very little yellowish; and when the red Circle surrounding them is quite pale. They should be opened with very fine sharp-pointed Scissars; this does not give the Patient the least Pain; and when a certain Number of them are opened, a Spunge dipt in a little warm Water is to be repeatedly applied to suck up and remove that _Pus_, which would soon be dried up into Scabs. But as the Pustules, when emptied thus, soon fill again, a Discharge of this fresh Matter must be obtained in the same Manner some Hours after; and this must sometimes be repeated five or even six Times successively. Such extraordinary Attention in this Point may probably be considered as minute, and even
