Laxative Medicines. Castor Oil.- In purchasing this, always ask for cold drawn. The dose of this, for a child, is from half a tea-spoonful to a dessert-spoonful; for a grown person, from a dessert spoon to two table-spoonfuls.   Senna Tea.-O n half an ounce of senna and one ounce of figs, tamarinds, or raisins, pour a pint of boiling water; let it stand for four or five hours, then strain it off; a small tea- cupful may be taken every hour till it operates; or the same ingredients may be boiled in a pint and a half of water, till reduced to a pint, and then strained off; in this case a smaller dose will suffice.   Salts.- Epsom, Glauber, or Cheltenham Salts. As many fatal mistakes have occurred by persons taking spirits of salt, oxalic acid, or other poisonous drugs, supposing them to be the safe and proper medicinal salts, here is a simple test by which to try them. Before wetting the salts, take a small pinch and throw it in the fire; if it is the proper thing, it will dissolve like snow; but if you see it spirtle, and send up a blue flame (like a match) you may be sure it is something amiss. Another thing by which you may ascertain, is this; medicinal salts have a bitter and soapy taste; but the poisonous salts have a sharp acid burning taste. The best way of taking salts is, to dissolve an ounce in a pint of water, and take a wine-glassful every morning, fi that be the design, or every half hour till it operates.   Rhubarb and Magnesia. For a grown person; a large tea-spoonful of magnesia, and as much rhubarb as will lie on a sixpence; to be mixed in a glass of cold water, or simple peppermint water. The best way of mixing it is, to lay the powder at the top of the liquid, let it stand till it has all settled, and then stir it up. Sal polychrest and rhubarb make a very good laxative medicine for children who are weak in the stomach and bowels. Take one drachm of sal polychrest, and two scruples of rhu- barb in powder; mix them, and make into twelve powders; one or two to be taken daily. This is the dose for a child about five years old.   Opening Electuary. A very useful family medicine, particularly good for those who are troubled with asthma or rheumatism. One ounce of senna powder, half an ounce of flour of sulphur, two drachms of powdered ginger, half a drachm of saffron powder, four ounces of honey. The size of a nutmeg to be taken night and morning.   Another Electuary. Equal parts of sulphur and cream of tartar mixed up with treacle. If an equal part of magnesia be added, it forms the electuary recommended for the piles.   Laxative Syrup. Take one ounce of senna leaves, and having carefully picked out every bit of stalk, pour over them one pint of boiling water; let this boil till one half remains, then pour the whole into a china bason, and covering it up, set it aside for twenty-four hours; strain it off through a linen rag, and adding four ounces of treacle, put it over a fire till it becomes so much heated as to be thoroughly mixed together. When cold, cork it up for use, and keep it in a cool place. This syrup is chiefly intended for children; the dose may be from a tea-spoonful to a table-spoonful, according to the age and strength of the child; if not active enough, powdered jalap may be added.   Calomel Powder. Of calomel four grains, of jalap twelve grains, of ginger four grains. This is a dose for a grown person; for a child it must be proportionably lessened. It must be taken in jelly, honey, treacle, or sugar; not in any liquid; and during its operation all cold must be avoided. This medicine is good for indigestion, and irregularity of the bile.   Dr. Bailie's Prescription for Sick Headaches. Turkey rhubarb, finely powdered, three grains; pure soda powder dried, ten grains; sal volatile, fifteen drops. To be taken between breakfast and dinner in a glass of warm water.   Electuary for the Rheumatism. Communicated by an eminent Surgeon for the benefit of his poor neighbours. -Powdered gum-guaiacum eight grains, flour of sulphur two drachms, powdered rhubarb fifteen grains, cream of tartar one drachm, powdered ginger thirty grains, nut- meg eight grains. To be made into an electuary with two ounces of clarified honey; a tea-spoonful to be taken night and morning. Powder for the Rheumatism. One ounce of Turkey rhubarb, half an ounce of gum- guaiacum, one ounce of sulphur, one ounce of flour of mustard, one ounce of nitre; all beaten very fine in a mortar, a tea- spoonful taken in a glass of warm water two or three times a day; when the pain has abated less will do.   Emetics.- Ipecacuanha Powder. Dose for a grown person, fifteen or twenty grains, to be taken in sugar and warm water; for a child, from three to fifteen grains. Ipecacuanha or antimonial wine, two table- spoonfuls at first, and another in ten minutes, if the first has not operated; for a child, from two tea-spoonfuls to a table-spoonful (according to its age), every quarter of an hour, till vomiting takes place. Flour of mustard will act as an emetic. -Camomile tea, also, when the stomach is in a state to require it.   COUGH MEDICINES. Essence of Malt, for a Cough or Hoarseness. Two quarts of the very strongest sweet-wort, set over a slow fire, in a very clean tin saucepan, with the lid on, till it boils; then take off the lid, and stir it frequently, not taking of the scum, but stirring it down. When it has become so thick a syrup as with difficulty to drop from the spoon, it is done; when cold, put it into bottles, and cork it tight. Take two tea-spoonfuls twice a day, and the last thing at night.   Vegetable Syrup for the same purpose. Boil two table-spoonfuls of linseed in a pint of soft water, till reduced to one half; strain it, and add one pint of lemon- juice,* and three pounds of the coarsest brown sugar. Let it simmer altogether over a slow fire, for upwards of two hours, skimming it as the scum rises. This is supposed to be Godbold's celebrated and very expensive syrup. Whether or not it is so, it has been found very successful in relieving hoarse- ness or husky cough.* At the season when lemons are very expensive, the same purpose may be answered by using good white-wine vinegar.       For a dry tickling Cough. One ounce of spermaceti in powder, one table-spoonful of honey, a table-spoonful of simple peppermint-water, and the yolk of a new-laid egg; beat these up together, and take a spoonful often. Honey and vinegar, simmered together, have often been found beneficial in an asthmatic cough. Or the following:- Sugar-candy, bruised, oil of sweet almonds, and lemon-juice mixed together.   Cough Drops. For Hooping Cough, and for coughs in general, when not attended with any great degree or fever.-Oxymel of squills, paregoric elixir, antimonial wine, and sal volatile, in equal parts. The dose for a grown person is two small tea-spoonfuls at going to bed, and one tea-spoonful twice a day besides; for children, according to their age. Syrup for cough and soreness of the stomach, chiefly used for infants. -Syrup of white poppies, oil of sweet almonds, of each one ounce, antimonial wine one drachm. It may be made with syrup of violets instead of syrup of poppies; and, unless the child is very restless, will answer quite as well. The dose is from a tea-spoonful to a dessert-spoonful (according to the child's age), two or three times a day. White emulsion, for cough and soreness of the stomach.- Six ounces (that is, twelve table-spoonfuls,) of boiling water, sweetened with loaf sugar; when cold, put it in a large phial, and add two ounces of the oil of sweet almonds, and as much sal volatile as will cause the oil to mix with the water, so that when you shake the bottle you will no longer see the oil, but the whole will appear white like milk. A table-spoonful of this may be taken frequently. If the cough is very troublesome, or the stomach very sore, half an ounce of tincture of tolu may be added, or half an ounce of paregoric elixir; but not if the person is feverish.   Strengthening Medicines. Bark may be prepared for use, either by boiling or pouring boiling water over it, in the following ways: A n ounce of bark (bruised) boiled in a pint and a half of water, till reduced to a pint; then strain off, and add a tea-spoonful of weak spirits of vitriol; or, take one ounce of bark in powder, and one ounce of tincture of myrrh; pour on them a pint of boiling water; let them stand in a bottle two or three days, frequently shaking it; after this, it may be taken; pour off the liquor clear from the sediment, and take a wine-glassful twice a day. This is a good medicine for children after the measles, or any other lowering disease; the quantity, of course, must be reduced according to their age. For a child of six or seven years old, a table-spoonful will be a proper dose. For a weak stomach and want of appetite. One ounce of camomile flowers, half an ounce of dried Seville orange or lemon-peel (that is, the yellow rind quite free from the inner white); pour on them a quart of boiling water, and take a wine-glassful the first thing in the morning, and twice in the day beside.   Another.- For nervous weukness and lowness of spirits.- One ounce of red rose leaves dried, two drachms of gentian roots, and two drachms of orange-peel (as above), cut in small pieces; pour over them a quart of boiling water; let it stand twoor three hours, then strain off, and add a tea-spoonful of weak spirits of vitriol. A glass of this may be taken twice or thrice a day. Daly's Elixir, or Tincture of Senna. One galon of aqua vita, half a pound of raisins, one drachm of saffron, two ounces of anniseed, two ounces of coriander seeds, two ounces of sweet fennel, to each two ounces of parsley, two ounces of the best Turkey rhubarb, two ounces of Spanish juice, two ounces of senna, two ounces of elicampane. To stand in a gentle warmth for two or three weeks, shaking it often; them stand two or three months; then filter, and add half a gallon more spirit to the drugs. After standing six weeks or two months, strain of the spirit; boil the drugs in a little water; squeeze and mix the liquor with the above half gallon of spirit, and it will make a useful family medicine... The first tincture is far stronger than the bought Daffy 's, and is very useful, administered with an equal quantity of warm water; and ought never to be taken genuine but in very urgent cases, free from fever.   Recipe for the Hooping Cough. Honey four drachms, liquorice roots four drachms, flowers of benzoin, opium one drachm, camphire two scruples, oil of anniseed half a drachm, salt of tartar one ounce. Digest them together three weeks in a quart of rectified spirits of wine, closely stopt, often shaking it.

One spoonful of honey, one spoonful of oatmeal. Pour to them a quart of boiling water, stirring the mixture well; let it cool, and drink half at night going to bed, and the other half in the morning, fasting. Stir it well before drinking; repeat this every day constantly, making the drink fresh every day.   To make an improved Tincture of Bark. Red bark, grossly powdered, one ounce; of snake root, in powder, six drachms; saffron, one drachm and a half; cochineal, ten grains; orange-peel, one ounce and a half. Steep the above articles in one pint of the best brandy, and you will have a tincture equally good as the famous Dr. Husham 's.
