Temperatures varying with speed and air temperatures. -------------------------------------------------------- "We are sending you a chart showing the various rises and falls of water and air temperatures during the car's mileage for 4 days. The readings are taken every 50 miles, irrespective of speed. The speed of the car is just as the traffic etc., allows. The curves therefore show what actually happens during a 250 mile run".
