Take, rhubarb, in fine powder, carbonated kali, of each thirty grains; ginger, in fine powder, one scruple; balsam of Peru, a sufficient quantity to form a mass; divide it into twenty-four pills. Dose, three or four every other night, at bed-time. At the same time, to restore the tone of the digestive organs, the following decoction should be taken:-- Take of Peruvian bark, six drachms; Cascarilla bark, two drachms. Bruise them in a mortar, and boil them in a pint and a half of water for a few minutes; strain off the liquor while hot, then add tincture of bark, two ounces; diluted nitric acid, a drachm and a half. Dose, four large spoonsful, three times a day. 1357. _Cramp and Spasm._--It frequently happens that persons are extremely annoyed by cramp during the night, which may be relieved by the following tincture:-- Take of tincture of opium, two drachms; ether, half an ounce. Mix them together, and take thirty or forty drops every night, at bed-time. 1358. _How to apply Blisters._--A considerable degree of pain and inflammation often follows the application of blisters, which may be obviated, by covering the blister-plaster with very thin muslin, which will prevent any part of it remaining on the skin, after the removal of the blister. The muslin should be pressed down, and rubbed with the finger upon the surface of the blister-plaster. 1359. _Mustard Plasters_--Should be covered with muslin, or the poultice put in a cloth bag, before being applied to the skin. 1360. _To prevent Lock-jaw._--Immerse the part injured in strong lye, as warm as can be borne. But first, as in all cases of wounds, apply spirits of turpentine on lint. 1361. _For a Stiff Joint._--An ointment made from the common ground-worms, which boys dig to bait fishes, rubbed on with the hand, is said to be excellent, when the sinews are drawn up by disease or from a sprain. 1362. _Easy Method of curing the Scurvy._--The root of the garden carrot abounds in a nutritious saccharine juice, and is slightly aromatic. These are desirable properties against the scurvy. To experience the good effects of these properties, _the roots must be eaten raw_. There is nothing unpleasant in this; on the contrary, it is what the common people often do by choice. These roots would keep well during the longest voyage, packed up in casks, having the interstices filled with sand. Each sailor might be allowed to eat one root every day, or every other day, according to the state of their health, and the quantity of roots on board. 1363. _To make Cliver, or Goose-grass Ointment; remarkable for its salutary effects in cases of inveterate Scurvy._--To a pound of hog's-lard melted, without spice or salt, put as much clivers as the lard will moisten, and boil them together over a slow fire; after stirring it till it becomes a little brown, strain it through a cloth; and when cold, take the ointment from the water that will remain at the bottom, and it will be fit for use.
