Description
The object of Wethered's invention "is to render practicable the substitution of brick or other argillaceous material in the construction of hot air furnaces, for iron and thus obviate the drying and deadening effects of the latter material upon the air warmed by contact with the same or by the heat radiated therefrom. Air heated by argillaceous substances, it may be well known is supplied to the room in a more moist and healthy state than air heated by metal, as the former does not become so intensely heated as to burn the air and deprive it of moisture nor does the heat radiated therefrom, in mingling with the air, impart to it an unhealthy and disagreeable smell."
