As noted by the arrows, thewarm air from furnace chamber passesstraight up through warm air regis-ter and gradually diffuses as it ap-proaches ceiling, then follows alongceiling to outer walls, where it gradu-ally descends to replace the air whichlias been cooled by contact with the ex-posed surfaces.

But there is still another and veryimportant reason why a plant installedin this manner would not prove success-ful. All along the walls of the buildingthe air is falling as it comes in con-tact with this exposed surface, and 54 tion a short time, although it is coolerthan the air coming directly from fur-nace, and the effect of this circulationis to envelop the whole interior of thebuilding in a continuous current
