This disease begins first with chilness and shi-vering, succeeded with heat, and then heat and cold succeed each other by turns. The next day the fever comes on with great sickness, thirst and loss of appetite; the tongue is white but not dry, with a little cough, a heaviness of the head and eyes, and a continual sleepiness : there is a sneezing, and swelling of the eye-lids, sometimes a watry humour drops from the nose and eyes, which is a certain sign the spots will soon appear; which are small in the face, but broad and red on the breast, not rising above the surface of the skin. The patient sometimes vomits, but oftner has a looseness with greenish stools.

These symptoms increase and continue till the fourth, sometimes till the fifth day, at which time the spots appear like flea-bites, increasing in number and size, running together in some places, and rendering the face variously spotted; from the face the spots proceed gradually to the breast, belly, thighs and legs. The vomiting ceases after this, but the cough and fever increase, with difficulty of breathing : the weakness and defluxion on the eyes, sleepiness and want of appetite still continue.

On the sixth day or thereabouts, the skin of the face and forehead begin to grow rough, and the cuticle breaking, the pustules die away, while the spots on the rest of the body continue broad and red. On the ninth day they all vanish, and fine thin scales like flower fall from the skin at that time.

In the cure it will be proper to bleed before the eruption of the pustules, to prevent an inflammation of the lungs; and then give either a gentle clyster, or a laxative with manna, to relieve the cough, "Take oil of sweet almonds and the pect-"ral syrup of each two ounces, of white sugar candy enough "to bring them to the thickness of a lambative." The patient may take a little of this as often as the coughing is trou-ble some: likewise take of the pectoral decoction a pint and a half, of the pectoral syrup three ounces, mix them ; the dose of this is three ounces four times a day, and at night, give an ounce of diacodium mixt with three ounces of simple alexite-rial water, increasing or diminishing the dose according to the age, but this must be used sparingly during the increase of the distemper. Sometimes after the measles disappear, there will happen a difficulty of breathing, a fever, and other symptoms resembling; an inflammation of the lungs. Now as this is caused by the striking in of the spots, it may be prevented by giving fifteen grains of the bark every three hours, with five grains of the watry extract of myrrh, or more or less according to the age, in small cinnamon water; for the bark will cause the fever and cough to cease on the seventh day, and the efflore-scence will not leave the face till after the twelfth. When the spots strike in before the due time, or become livid or of a bad colour, rub the whole body with a hot flannel, and then give the following bolus: "Take of virginian snake-root fifteen "grains, of castor ten grains, of camphire three grains, of "syrup of clove july-flowers enough to make a bolus." If the patient sweats profusely, his linen must be changed for others dry and warm, taking care not to admit sudden cold, for that will strike in the pustules: if a looseness appears when the scales fall off, it must not be hastily stopt, but a moderate dose of rhubarb may be given now and then, with toasted nutmeg.
