One point is in the firebox, at aposition denoted in the diagrammatic longitudinal section ofthe boiler as r=. Another point was at Tj in the two records give the temperature of the gases of com-bustion entering and leaving the ordinary boiler tubes of thelocomotive. Two other measurements were recorded, viz., atpoints denoted by T, and T^. These two records give thetemperatures of the gases of combustion feeding the super-heater elements—the first the temperature of the gases as they 638 AMERICAN ENGINEER.
