By raising or lowering the water in the pan,more or less of the coil is submerged, and more or less moisture drivenoff into the air. Figure 37 is a detail of the manner of admitting air through the audi-torium floor. The arches are of brick, and the whole space betweenthem and the wooden floor is filled with warmed air, which enters through. JTMIQUej ch^}^ Figure 37. 140 VENTILATION AND HEATING. ii^jL
