When the fever runs high, and the head symptoms are severe, it may be necessary to bleed, but if not, a blister is to be laid on the nape of the neck, and perhaps two small ones behind the ears, to relieve the tumefaction of the eyes, and where the want of sleep demands it, a draught at bed-time, composed of fifteen grains of nitre dissolved in two ounces of water, with twenty-five drops of laudanum; or to children, from three to ten drops in a little gruel, according to their ages. Such, in mild or _distinct_ small-pox, is generally all the treatment needed; and even in the aggravated _confluent_, till the time of disquamation often no other means are necessary. In cases, however, where the rash, after showing favourably, suddenly recedes from the skin, or only partly comes out, the patient must be put into a warm, or rather hot bath for three or four minutes; and when the pulse falls, and becomes small and feeble, as it becomes absolutely necessary to bring back the rash to the skin, hot wine and water must be given, together with soups, tonics, and stimulants, till the invigorated constitution has power to re-act. Should this not have been called for, a system of careful feeding, aided with wine and bark, must be commenced at the period when nature begins to throw off the dead eruption. The great object to be observed in the treatment of small-pox, is to keep the patient cool, and on the lowest regimen, till the disquamation begins to act freely on the bowels, and to allay fever by cooling drinks. As soon as the patient is convalescent, the diet should be light, and composed chiefly of farinaceous foods, puddings, custards, &c. The body should be bathed once a week, and the cuticle excited by dry rubbing with a towel, and especial care taken for some weeks to keep children from the contact of the patient, who should for that time take an aperient every three days. To prevent the face and neck from being pitted, each pock in that neighbourhood should be lightly wetted with a weak solution of lunar caustic, at the period when the pustules are filled with a transparent fluid, while they are yet round, and before suppuration has set in or the tops of the vesicles grown flat—or in other words, at the end of the second stage.
