 presence* of moisture in their walls. This 

 moisture may be held either mechanically, 

 as by capillary attraction in the bricks, 

 mortar, and plaster; or chemically, in the 

 hydrate of lime. Moisture held mechani- 

 cally is removable by air and warmth ; 

 chemically-held moisture is removed grad- 

 ually by the action of carbonic acid con- 

 tained 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
