Or, first give half a dram or a dram of vitriolated tartar, to incite the phlegm, or a quarter of an ounce of oxymel of squills, and then warm water mixt with unsalted butter very plentifully, or a scruple of ipecacuauha. The common medicine is a spoonful of the juice of lemons, with a scruple of the salt of wormwood. When the patient vomits yellow bilious fluff, which proceeds from a bad digestion, and has its feat in the duodenum, this may be cured by gentle laxatives of manna and rhubarb. If the biliary duels seem to be too lax, give the Peruvian bark, bitter tincture, and steel medicines. When its passages are plug'd up by flimy matter, or a stone in the gallbladder, give soapy medicines and salt-water.
When vomiting proceeds from poisons, give large quantities of milk and sweet oil. When from the gout in the stomach, give half a dram of the compound powder of contrayerva with five grains of camphire. Likewise, put the feet in warm water, rub them well with a coarse cloth, and inject clysters.
Vomiting caused by a stoppage of the monthly courses or the bleeding piles, may be cured by absorbents, by gentle laxatives, and more especially by bleeding, or causing the flux to return.

When there is a pricking pain or stitch in the left side, add an ounce of diacodium to the mixture. To bring the humours downward, give any common clyster with a dram of salt-petre. For outward application, dissolve a dram of camphire in an ounce of oil of sweet almonds, and anoint the pained side therewith; if the blood is thrown up in great quantities, with loss of strength, make ligatures upon the legs and arms, or dip them in cold water: when the fit is over, the patient may drink water in which hot iron has been quenched; or, which is better, butter milk, and purge with half a dram of rhubarb.
