The air passing from the lower flues c c through the apertures beneath the horizontal partition, and coming in immediate contact with the surface of the cockle, finds its way into the upper air-chamber e e through the numerous pipes or openings of the upper division, by which circuit its velocity will be sufficiently retarded to obtain the necessary elevation of temperature from the heated cockle.
In the plan submitted by Sylvester, 1835, for warming and ventilating the Houses of Parliament (E, Fig. 2474), the fresh air was to be admitted through an underground channel a b to a cockle c beneath the floor of the building.
