BY FIRE. Much mischief frequently arises from the want of a little presence of mind on such occasions, when it is well known that a small quantity of water speedily and properly applied, would obviate great danger. The moment an alarm of fire is given in a house, some blankets should be wetted in a tub of water, and spread on the floor of the room where the fire is, and the flames beaten out with a wet blanket. Two or three pails of water thus applied, will be more effectual than a larger quantity poured on in the usual way, and at a later period. If a chimney be on fire, the readiest way is to cover the whole front of the fire-place with a wet blanket, or thrust it into the throat of the chimney, or make a complete inclosure with the chimney-board. By whatever means the current of air can be stopped below, the burning soot will be put out as rapidly as a candle is by an extinguisher, and upon the same principle. A quantity of salt thrown into water will increase its power in quenching the flames, and muddy water is better for this purpose than clear water. Children, and especially females, should be informed, that as flame tends upward, it is extremely improper for them to stand upright, in case their clothes take fire; and as the accident generally begins with the lower part of the dress, the flames meeting additional fuel as they rise, become more fatal, and the upper part of the body necessarily sustains the greatest injury. If there be no assistance at hand in a case of this kind, the sufferer should instantly throw herself down, and roll or lie upon her clothes. A carpet, hearth rug, or green baize table cloth, quickly wrapped round the head and body, will be an effectual preservative; but where these are not at hand, the other method may easily be adopted. The most obvious means of preventing the female dress from catching fire, is that of wire fenders of sufficient height to hinder the coals and sparks from flying into the room; and nurseries in particular should never be without them. Destructive fires often happen from the thoughtlessness of persons leaving a poker in the grate, which afterward falls out and rolls on the floor or carpet. This evil may in a great measure be prevented by having a small cross of iron welded on the poker, immediately above the square part, about an inch and a half each way. Then if the poker slip out of the fire, it will probably catch at the edge of the fender; or if not, it cannot endanger the floor, as the hot end of the poker will be kept from it by resting on the cross. In cases of extreme danger, where the fire is raging in the lower part of the house, a Fire Escape is of great importance. But where this article is too expensive, or happens not to be provided, a strong rope should be fastened to something in an upper apartment, having knots or resting places for the hands and feet, that in case of alarm it may be thrown out of the window; or if children and infirm persons were secured by a noose at the end of it, they might be lowered down in safety. No family occupying lofty houses in confined situations ought to be without some contrivance of this sort, and which may be provided at a very trifling expense. Horses are often so intimidated by fire, that they have perished before they could be removed from the spot; but if a bridle or a halter be put upon them, they might be led out of the stable as easily as on common occasions. Or if the harness be thrown over a draught horse, or the saddle placed on the back of a saddle horse, the same object may be accomplished.

      ADULTERATIONS in baker's bread may be detected, by mixing it with lemon juice or strong vinegar: if the bread contains chalk, whiting, or any other alkali, it will immediately produce a fermentation. If ashes, alum, bones, or jalap be suspected, slice the crumb of a loaf very thin, set it over the fire with water, and let it boil gently a long time. Take it off, pour the water into a vessel, and let it stand till nearly cold; then pour it gently out, and in the sediment will be seen the ingredients which have been mixed. The alum will be dissolved in the water, and may be extracted from it. If jalap has been used, it will form a thick film on the top, and the heavy ingredients will sink to the bottom.

      AGUE. Persons afflicted with the ague ought in the first instance to take an emetic, and a little opening medicine. During the shaking fits, drink plenty of warm gruel, and afterwards take some powder of bark steeped in red wine. Or mix thirty grains of snake root, forty of wormwood, and half an ounce of jesuit's bark powdered, in half a pint of port wine: put the whole into a bottle, and shake it well together. Take one fourth part first in the morning, and another at bed time, when the fit is over, and let the dose be often repeated, to prevent a return of the complaint. If this should not succeed, mix a quarter of an ounce each of finely powdered Peruvian bark, grains of paradise, and long pepper, in a quarter of a pound of treacle. Take a third part of it as soon as the cold fit begins, and wash it down with a glass of brandy. As the cold fit goes off, and the fever approaches, take a second third part, with the like quantity of brandy; and on the following morning fasting, swallow the remainder, with the same quantity of brandy as before. Three doses of this excellent electuary have cured hundreds of persons, and seldom been known to fail. To children under nine years of age, only half the above quantity must be given. Try also the following experiment. When the cold fit is on, take an egg beaten up in a glass of brandy, and go to bed directly. This very simple recipe has proved successful in a number of instances, where more celebrated preparations have failed.

      AIR. Few persons are sufficiently aware, that an unwholesome air is the common cause of disease. They generally pay some attention to what they eat and drink, but seldom regard what goes into the lungs, though the latter often proves more fatal than the former. Air vitiated by the different processes of respiration, combustion, and putrefaction, or which is suffered to stagnate, is highly injurious to health, and productive of contagious disorders. Whatever greatly alters its degree of heat or cold, also renders it unwholesome. If too hot, it produces bilious and inflammatory affections: if too cold, it obstructs perspiration, and occasions rheumatism, coughs, and colds, and other diseases of the throat and breast. A damp air disposes the body to agues, intermitting fevers, and dropsies, and should be studiously avoided. Some careful housewives, for the sake of bright and polished stoves, frequently expose the health of the family in an improper manner; but fires should always be made, if in the height of summer, when the weather is wet or cold, to render the air wholesome; and let the fire-irons take care of themselves. No house can be wholesome, unless the air has a free passage through it: dwellings ought therefore to be daily ventilated, by opening the windows and admitting a current of fresh air into every room. Instead of making up beds as soon as people rise out of them, a practice much too common, they ought to be turned down, and exposed to dry fresh air from the open windows. This would expel any noxious vapours, and promote the health of the family. Houses surrounded with high walls, trees, or plantations, are rendered unwholesome. Wood, not only obstructs the free current of air, but sends forth exhalations, which render it damp and unhealthy. Houses situated on low ground, or near lakes and ponds of stagnant water, are the same: the air is charged with putrid exhalations, which produce the most malignant effects. Persons obliged to occupy such situations should live well, and pay the strictest regard to cleanliness. The effluvia arising from church-yards and other burying grounds is very infectious; and parish churches, in which many corpses are interred, become tainted with an atmosphere so corrupt, especially in the spring, when the ground begins to grow warm, that it is one of the principal sources of putrid fevers, which so often prevail at that season of the year. Such places ought to be kept perfectly clean, and frequently ventilated, by opening opposite doors and windows; and no human dwelling should be allowed in the immediate vicinity of a burying ground. – The air of large towns and cities is greatly contaminated, by being repeatedly respired; by the vapours arising from dirty streets, the smoke of chimneys, and the innumerable putrid substances occasioned by the crowd of inhabitants. Persons of a delicate habit should avoid cities as they would the plague; or if this be impracticable, they should go abroad as much as possible, frequently admit fresh air into their rooms, and be careful to keep them very clean. If they can sleep in the country, so much the better, as breathing free air in the night will in some degree make up for the want of it in the day time. Air which stagnates in mines, wells, and cellars, is extremely noxious; it kills nearly as quick as lightning, and ought therefore to be carefully avoided. Accidents occasioned by foul air might often be prevented, by only letting down into such places a lighted candle, and forbearing to enter when it is perceived to go out. The foul air may be expelled by leaving the place open a sufficient time, or pouring into it a quantity of boiling water. Introducing fresh air into confined rooms and places, by means of
