Since these compositions are so easily made, they might occasionally be prepared on board; Instead thereof, I would advise the seaman to furnish the box with camphor and soap; and instead of rectified spirit, good rum or brandy will answer equally as well. C. _Sweet oil_: This ought to be pure and good; it is of many uses in medicine, which I shall treat of as occasion requires. D. _Sweet spirit of nitre._ _This is a spirit distilled from spirit of wine one quart, and spirit of nitre half a pound, according to the art of chymistry._ In regard to its virtue, it is an excellent medicine in most acrimonious cases, and acts principally as a gentle diuretic; besides this, it is of an antispasmodic and antiputrescent quality, and therefore useful in all kinds of inflammatory disorders, particularly of the putrid kind of fevers; which I shall, in the course of this work, take notice of. E. _Honey_: This is a useful article, which ought to be plenty, and of the best kind; it is particularly useful for making gargles, clysters, poultices, &c. &c. as shall be farther specified. F. _Yellow basilicon_: _Take olive oil, yellow bees wax, yellow rosin, Burgundy pitch, of each half a pound, turpentine two ounces; melt the whole, and mix them properly._ This is an external digestive application to cleanse ulcers, and to make them discharge good matter, by which the inflammation will abate. G. _Elixir of Vitriol_: _Take stomachic elixir one pint, oil of vitriol four ounces; mix them, and filter it through paper._ This is an excellent elixir for weak stomachs, that proceed from bile and other causes of indigestion; it is also a great specific against the scurvy, and the like habits; as also in feverish complaints. The dose is from 20 to 40 or 60 drops, in a little water. H. _Elixir proprietatis_: _Take of myrrh in powder one ounce and an half, succotrine aloes in powder an ounce, saffron four ounces, of dulcified spirit of vitriol six ounces, of rectified spirit of wine twenty-four ounces; digest them in a sand heat for four days, and then pour off the elixir from the dregs._ This elixir is an excellent stomachic, it will promote digestion, strengthen the stomach, and create an appetite; it will also keep the body gently open, and on that account be of great benefit against many ailments in the bowels. The dose is about a drachm or two, or a middling spoonful; to be taken either by itself, or in a glass of wine, and makes a most agreeable bitter. I. _Lenitive Electuary_: _Take dried figs one pound, tamarinds, cassia, french prunes, each half a pound, sena leaves eight ounces, coriander seed four ounces, liquorice root three ounces, double refined sugar two pounds and an half; reduce the sena and coriander to a powder, and sift it through a sieve, boil the figs, cassia, prunes, and liquorice into a pulp, and strain these also, then mix the powder gradually amongst it, and make it, with the help of the sugar, into an electuary._
