Fig. 4. the front of the heater, with its grated openings, takes thejilaccof the panel. From figs. 3 and 4 it will be seen that the bottom of thewooden case stands a few inches above the floor. This allowscold air to flow into it where it is warmed by the coil, andthen flows out through the grated opening into the car. Tliewarm air thus communicates its heat to the feet of passengersbefore it rises to the upper part of the car. In their descriptive circular the Consolidated Comjiauy .say : To prevent the oxidation of the resisting conductor a gal-vanized wire is used which has tlie advantage of not oxidizingreadily even when a high tenijierature is maintained.
