Moist Air in Dwellings.

An eininent engineer has recently broached the theory that the summer condition of temperature, 62 to 68 deg., and relative humidity, 80 to 85 deg., are not desirable or attainable at other seasons in the heating of dwellings. His argument is that the dry air of America possesses both curative and preventive qualities of great value, and that moist air, which promotes vegetable growth, is, on sanitary grounds, not desirable for breathing ; then, too, the dew point is far below the freezing point of water in well-warmed and ventilated rooms, where there is nothing of that sensation of dryness which is usually held to accompany the heat of a furnace, constructed and arranged according to the ordinary plan, when not supplied with water for evaporation.
