are to be cooled, and cold parts warmed, often both at the same time, so as to restore the proper balance of vital action. Gentle progressive measures are always best in this, especially with children. Cold feet are warmed by bathing (see) and fomentation (see). A heated head may be cooled with cold towels (see) or with soap lather (see). This principle of seeking a proper balance should be borne in mind throughout all our treatment. Its importance can hardly be exaggerated, as the restoration of this balance alone will frequently effect an almost magical cure where drugs have been wholly ineffective.

      Air.—The Black Hole of Calcutta is an object lesson of how necessary to life is the renewal of the air supply. Few people, however, reflect that a deficient supply of fresh air may affect the health, though far short of what will cause death. Many hospitable people will invite so many friends to their houses that the amount of air each can get is less than 1–20th of what the law insists shall be provided for the prisoners in our gaols. Superabundant provision is made for the wants of the stomachs of these guests, but none at all for the more important organ—the lungs. The headaches and lack of appetite next morning are attributed to the supper instead of the repeatedly breathed air, for each guest gives off almost 20 cubic feet of used-up air per hour. No one would ask their guests to wash with water others had used; how many offer them air which has been made foul by previous use? Everyone knows that in our lungs oxygen is removed from the air inhaled, and its place taken by carbonic acid gas. Besides this deoxydizing, the air becomes loaded with organic matter which is easily detected by the olfactory organs of those who have just come in, and so are in a position to promptly compare the air inside with what they have been breathing. The exhilaration produced by deep breathing of pure air is well known. What, therefore, prevents everyone enjoying it at all times? Simply the fear of "cold"—an unfortunate name for that low form of fever properly called catarrh, and a name which is largely responsible for this mistaken idea. "Colds" are now known to be infectious, being often caught in close ill-ventilated places of public assembly. Most people suppose that it is the change from the heat to the cold outside that gives them "cold," whereas the "cold" has been contracted inside. There is no lack of evidence that wide open windows day and night, summer and winter, so strengthen and invigorate that colds are rarely taken, and when taken, generally in a mild form. This also applies to influenza. If delicate consumptives can stand, without any gradual breaking-in to it, unlimited fresh air, and can lie by day and night in open sheds, no one need dread at once to adopt the open-window system. Although few will believe it, until they try it, a wide open window does not produce a draught as does one slightly opened, and it is safer and pleasanter to go in for abundant fresh air than to try what might be called a moderate course. Many think that with an open window the heat of the fire is practically wasted. They do not know that the radiant heat of the fire will warm the person it falls on even though the temperature of the room is very low. The Canadian hunter before his fire is comfortably warm, though the air around him may be a long way below zero. Extra clothing may be worn if any chilliness is felt. While the body is warm cold air has an invigorating effect on the lungs. Indeed, the body soon gets accustomed to the colder air, and those who practise keeping open windows winter and summer find that they do not require heavier clothing than those who sit with windows shut. A slight or even considerable feeling of coldness, when due to cold air and not to ill-health, will not harm.

      This is no new idea. Dr. Henry McCormac, of Belfast, father of the eminent surgeon, Sir William McCormac, wrote forty years ago:—"The mainly unreasoning dread of night air, so termed, is a great impediment to free ventilation by night. And yet day and night air is the same virtually, does not differ appreciably. The air by night, whether damp or dry, is equally pure, equally salubrious with the air by day, and calls not less solicitously for ceaseless admission into our dwellings. Air, ere it reaches the lungs, is always damp. Quite dry air is irrespirable. It needs no peculiar or unusual habitude in order to respire what is termed night air. Exposure to contact with the day air equally prepares us for exposure to the contact with the night air. We can multiply our coverings by night with even greater ease than we can by day, and with the most perfect certainty of producing and obtaining warmth. Good heavens! How is it that people are so wildly mistaken as if the great wise Deity, as he does by every exquisite and perfect adaption, did not intend that we should make use of the purest, sweetest air day and night always? The prospective results of breathing purest air by night are so infinitely desirable, the immediate enjoyment is so great that it only needs a trial to be approved of and adopted for ever. … Reasonable precautions—that is to say, adequate night coverings—being resorted to, no colour of risk to the lungs, even of the most delicate, can possibly ensue. For, it is stagnant air, air pre-breathed only, and not pure unprerespired air that makes lungs delicate. Although air, warmth, food, and cleanliness be cardinal conditions and essential to life, still the most important of all health factors is air—air pure and undefiled alike by day and by night. … The constant uneasy dread of taking cold, which haunts the minds of patients and their friends, is doubtless the one great reason why fresh air is thrust aside. And yet cold will not be caught, were it in Nova Zembla itself, by night, if only the sleeper's body be adequately covered. … The pulses or puffs of air that comes in ceaselessly, winter and summer, through open windows by night inspire just as if one slept in the open air, a sort of ecstasy. Gush follows gush, full of delightfulness, replacing the used-up air and purifying the blood. It has oftimes been said to me, 'I open the windows the moment I get out of bed;' to this I have uniformly replied, 'the moment to open the window is before you get into bed, not when you get out of it.' You cannot otherwise with entire certainty secure the benefit of an ever ceaselessly renewed night air so all essential to the blood's renewal and the maintenance of health. … With abundant night coverings there is no shadow of risk. There is none of rheumatism, none of bronchitis, in short no risk whatever. The only, the real risk, which we incur, is that of closing our sleeping chamber windows, of debarring ourselves of pure air during our repose."

      Appetite.—Should be an indication that food in general or some certain kind of food is needed by the body. Thus the appetite is the natural test of the amount and kind of food required. Over-eating and indulgence in stimulating foods and drinks, insufficient mastication and bolting of the food (see Over-eating, etc.) give us a false appetite, thus causing over-eating once more. A return to a simple and moderate diet will restore the natural appetite.

      Air Bath.—This may with advantage to the health of the skin and body in general, be indulged in every morning during some of the toilet operations, such as shaving, or preferably, dumbell exercise or Swedish gymnastics. If exercises are done in a nude condition the utmost freedom for the muscles is obtained. In a short time a notable change will be observed in the skin, which will lose its pasty appearance, and become soft flesh and of a healthy colour. If possible have the bedroom with windows facing the morning sun, so that the sunlight can also shine in. There are many sanitaria on the Continent and in America where this form of "bathing" is practised. Indeed, one of the great benefits of sea-bathing (overlooked in this country) is the exposure of the skin to air and light. Consequently if the weather and social custom permits, as much time as possible should be spent after immersion, lounging on the sand. A child's natural instinct leads it to play about after its bath in the sea instead of coming at once to be dressed.

      A young infant will enjoy lying on a rug on the floor without any clothing and with the window open. Older children will benefit by running about the garden in summer time in bare feet, and with only one garment, say a cotton frock.

      It is a great mistake to clothe children too warmly, indeed, the same may be said of adults. Garments should always be loose and porous, so as to allow of the beneficial action of the air on the skin. One of the objections to corsets is that they do not fulfil these conditions (see Tight Lacing, Skin, Care of.)

      Air-tight Covering.—The covering of oiled silk, or guttapercha, so frequently placed over wet bandages when these are applied to any part of the body, is not only useless, but often positively hurtful. It is true that the waterproof covering retains the moisture in the bandage, but it is also true that great heat is developed, and the waste products in the perspiration are retained on the surface of the skin. The effect of this is injurious in a very high degree. A little
