| To the Motorist THERMOMAMOMETER (RADIATOR TEMPERATURE INDICATOR) TEN REASONS FOR INSTALLING A RADIATOR TEMPERATURE INDICATOR ON YOUR CAR It Shows 1. Whether the engine is working normally or not. 2. If the water in the radiator has run out, and gives at least 30 minutes' warning, thus averting serious consequences. 3. Whether the belt of the ventilator is broken or loosened. 4. The Indicator shows you how to keep the engine at the right working temperature, with a consequent saving of petrol amounting to about 20 % or 30 %. 5. The Indicator shows immediately any abnormal condition of the engine, and is at the same time ornamental as well as useful. 6. The Indicator has a moveable pointer which is more plainly visible than that of any other similar device and is clearly visible by night. 7. The Indicator is nickel-plated, hence it lasts indefinitely. 8. The Indicator possesses the utmost reliability and is of simple construction, there being no delicate parts to get out of order. It is also independent of any column of mercury, with the consequent risk of leakage of the latter resulting in the driver being deceived. 9. All Indicators are carefully tested and verified. 10. The Indicators are cheap (see prices on outside cover). The last word in Indicators ! ! ! No water-cooled Engine should be without one ! SOLE AGENTS FOR THE UNITED KINGDOM: S. H.{Arthur M.
