FRESH AIR

For comfort and good health the ventilation and warming of rooms should be so arranged as to give people warm feet, cool heads, and pure air to breathe. Too often the oppo“site conditions are obtained which produce a cold, draughty floor, and warm stagnant air round the head —air, moreover, polluted by house dust, microbes, and fumes from stoves.

When people are crowded in a room and fe'el oppressed for want of fresh aii*, they generally think that they are suffering from lack of oxygen, or that they are being- poisoned by too much exhaled carbonic acid, or by some other poisonous matter in the air supposed to be given off by human beings. Popular books on hygieno have taught people to believe in such a poison, but quite erroneously. In such a crowded room a natural ventilation always takes place, as the warmer air in the room escapes through chinks and crannies .round the doors and windows, and the cold-, er outside air flows in to take its place. Warm air is lighter, and will get out., while cold air outside is lieav- : ier and will sink in. A great deal of air can flow quickly through very small holes as one knows wh’en a motor car tyre is punctured.
