    !3 feet of fresh air every hour, and to get this and remove the foul air is the aim of ventilation. Inasmuch as the air in a room can be changed about three times an hour, a room of 1000 cubic feet is the amount of air-space needed for one individual. This air-space can, of course, be diminished or increased according to the permanency of occupancy, labor, etc. In an ordinary dwelling 600 to 800 cubic feet of space should be allowed for each occupant, and in public buildings used only for a short time 300 cubic feet or even less is sufficient, considering that the air can be changed very often. While in the warmer climate of the South ven- tilation is a factor to be considered alone, in the colder climate of the North ventilation and heating go hand-in-hand, and this brings us to the methods of heating which are considered with their ven- tilating effects. In house-warming we endeavor to bring the temperature to about 68° F., which seems to be the normal for most healthy people. There is a great tendency to keep houses entirely too warm, the result of which is the undue prevalence of chronic catarrhal inflammations of the mucous membranes of the throat and nose. If the heat is moist a much lower temperature will suffice, and for this reason English houses seem cold, and are cold, to Americans coming from a dry climate, where they are accus- tomed to, and where a higher temperature is actually necessary. The various methods of heating are open fireplaces,stoves, hot-air furnaces, hot water, and steam.
