Moisture held mechanically is removable by air and warmth; chemically-held moisture is removed gradually by the action of carbonic acid contained in the air. A writer in the English Mechanic suggests the use of a dew-point thermometer as a means of determining whether a house is sufficiently free from moisture to be inhabitable. If we take a reading of this in the open air, in the shade, and protected from wind, we have the actual
