a fog, which depends on atmospheric changes, produced under different circumstances. The brisk air of the country often gives town-people a head-cold, and country people sometimes suffer in the same way when they visit town. During every season, certain people have "head-colds," coughs, and "feverish colds." These are produced by certain states of climate acting on certain states of constitution. At particular seasons such complaints abound--at others they abound still more; and again, from some singularity, they prevail so much, that people say, there is an _Influenza_. In simple cases, confinement to a pure and temperate air, warm drinks, and a warm bath, or at least a warm foot-bath, with an extra blanket, and a little more rest than usual, keeping to mild food and toast and water, and taking, if necessary, a dose of aperient medicines--is all that is required. In serious cases, the domestic treatment must become professional. Mustard plasters to the back, relieve the head-ache. Squills, and other medicines, "loosen" the outstanding cough. Bark and wine, and even cold baths, are sometimes requisite for the weakness left behind. But these things can only be used with discrimination by a regular professional man. 395. _For the Breath._--Persons who suffer from difficulty of breathing and oppression on the chest, will find great relief from the following simple contrivance. A tea-kettle is to be kept boiling, either over a fire or over a common night-lamp or nursing-candlestick. A tin tube is to be fitted on to the spout of the tea-kettle, of such length and form as to throw the steam in front of the sick person, who will then breathe in it. This prevents the distressing sensation occasioned by inhaling the cold night air, which will be felt by persons suffering from asthma or water on the chest, and which is not obviated either by clothing or fire. 396. _To relieve Asthma._--Soak some blotting-paper in a strong solution of saltpetre; dry it, take a piece about the size of your hand, and on going to bed, light it, and lay it upon a plate in your bed-room. By doing so, persons, however badly afflicted with asthma, will find that they can sleep almost as well as when in health. (Many persons have experienced relief from the use of this specific.) 397. _Relief for Asthma--another way._--Mix two ounces of the best honey with one ounce of castor oil, and take a tea-spoonful, night and morning. 398. _Gargle for Sore Throat._--On twenty-five or thirty leaves of the common sage, pour a pint of boiling water; let the infusion stand half an hour. Add vinegar enough to make it moderately acid, and honey to the taste. Use it as a gargle, several times a day. This combination of the astringent and emollient principle seldom fails to produce the desired effect.
