dying off from this disease. Living in impure air weakens nearly all organs and prepares them for disease. Schools that are well ventilated have less than one half as many pupils absent on account of sickness as those with poor ventilation.
Ventilation and Colds. The air in rooms not well ven- tilated is usually very dry. This causes the sweat to pass off from the body rapidly and carry with it heat, so that the room seems cold when it is really of a proper temperature.
A room with pure air at ...sixty-eight degrees will feel warmer than a room with impure dry air at seventy-two de- AJU AND HEALTH 107 grees. The change from the dry heated air to the moist cool air out doors is a common cause of a cold in the head, often called catarrh. In fact the over heated and poorly ventilated room is a frequent cause of all sorts of colds.
