409. _For a Cold in the Head._--What is called a head-bath is useful. Fill a wash-hand basin with boiling water, and add an ounce of flour of mustard; then hold the head, covered with a cloth to prevent the escape of the steam, over the basin as long as any steam arises. 410. _For a troublesome Cough._--Take of treacle and the best white wine vinegar six table-spoonfuls each; add forty drops of laudanum; mix it well, and put it into a bottle. A tea-spoonful to be taken occasionally when the cough is troublesome. 411. _For a sudden Hoarseness._--Mix one tea-spoonful of sweet spirits of nitre in a wine-glassful of water. This may be taken two or three times a day. 412. _Hoarseness._--A piece of flannel, dipped in brandy, and applied to the chest, and covered with a dry flannel, is to be worn all night. Four or six small onions, boiled, and put on buttered toast, and eaten for supper, are likewise good for colds on the chest. 413.--_Children's Coughs._--A few tea-spoonfuls of warm treacle taken occasionally, and particularly at bed-time, or when the cough is troublesome, will be found beneficial, especially for infants and children. 414. _For a "hacking" Cough._--Dissolve an ounce of mutton suet in a pint of milk, and drink it warm. 415. _For a Cough._--Mix vinegar and treacle in equal quantities, and let a tea-spoonful be taken occasionally, when the cough is troublesome. This is the recipe of Dr. James, of Carlisle. 416. _Quinsy, or Ulcerated Sore Throat._--Bake or roast three or four large onions or six smaller ones, till soft. Peel them quickly, and beat them flat with a rolling-pin or glass bottle. Then put them immediately in a thin muslin bag that will reach from ear to ear, and about three inches deep. Apply it speedily, and as warm as possible, to the throat. Keep it on day and night, changing it when the strength of the onions appears to be exhausted, and substituting fresh ones. Flannel must be worn round the neck after the poultice is removed. 417. _Saline Draught._--Dissolve one scruple of carbonate of potassa, (salt of tartar), in a table-spoonful of lemon-juice, and three table-spoonfuls of water; sweeten with lump sugar, and drink while it effervesces. This is an excellent remedy for sore throats, nausea, &c. 418. _Another._--Dissolve one drachm each of nitric acid and carbonate of potassa in three-quarters of a pint of water; add one ounce each of syrup of orange-peel and spirit of nutmeg, and mix. Two table-spoonfuls to be taken in fevers and inflammatory sore throats. 419. _To make Gargles._--For relaxed sore throat, mix five ounces of Cayenne pepper gargle, two ounces of infusion of roses, and one ounce of syrup of roses. Or, mix with the Cayenne pepper gargle, three ounces of vinegar, three drachms of tincture of myrrh, and four drachms of honey of roses. For inflammatory sore throats, mix six ounces of infusion of roses, one ounce of tincture of myrrh, and one ounce of honey of roses.
