To remove the hard callous horny warts which sometimes appear on the hands of children, touch the wart carefully with a new pen dipped slightly in aqua-fortis. It will give no pain; and after repeating it a few times, the wart will be found so loose as to come off by rubbing it with the finger. RING-WORMS. Rub mercurial ointment on the ring-worm previous to going to bed, and do not wash it off till morning. It will effect a cure if persevered in; sometimes in less than a week. MUSQUITO BITES. Salt wetted into a sort of paste, with a little vinegar, and plastered on the bite, will immediately allay the pain; and if not rubbed, no mark will be seen next day. It is well to keep salt and vinegar always in a chamber that is infested with musquitoes. It is also good for the sting of a wasp or bee; and for the bite of any venomous animal, if applied immediately. It should be left on till it becomes dry, and then renewed. ANTIDOTE FOR LAUDANUM. When so large a quantity of laudanum has been swallowed as to produce dangerous effects, the fatal drowsiness has been prevented when all other remedies have failed, by administering a cup of the strongest possible coffee. The patient has revived and recovered, and no ill effects have followed. GREEN OINTMENT. Take two or three large handfuls of the fresh-gathered leaves of the Jamestown weed, (called Apple Peru in New England,) and pound it in a mortar till you have extracted the juice. Then put the juice into a tin sauce-pan, mixed with sufficient lard to make a thick salve. Stew them together ten or fifteen minutes, and then pour the mixture into gallipots and cover it closely. It is excellent to rub on chilblains, and other inflammatory external swellings, applying it several times a day. TO STOP BLOOD. For a prick with a pin, or a slight cut, nothing will more effectually stop the bleeding than old cobwebs compressed into a lump and applied to the wound, or bound on it with a rag. A scrap of cotton wadding is also good for stopping blood. PERFUMERY, ETC. COLOGNE WATER. Procure at a druggists, one drachm of oil of lavender, the same quantity of oil of lemon, of oil of rosemary, and of oil of cinnamon; with two drachms of oil of bergamot, all mixed in the same phial, which should be a new one. Shake the oils well, and pour them into a pint of spirits of wine. Cork the bottle tightly, shake it hard, and it will be fit for immediate use; though it improves by keeping. You may add to the oils, if you choose, ten drops of the tincture of musk, or ten drops of extract of ambergris. For very fine cologne water, mix together in a new phial oil of lemon, two drachms; oil of bergamot, two drachms; oil of lavender, two drachms; oil of cedrat, one drachm; tincture of benzoin, three drachms; neroli, ten drops; ambergris, ten drops; attar of roses, two drops. Pour the mixture into a pint of spirits of wine; cork and shake the bottle, and set it away for use.
