The coefficient of friction between the rail and a block oftire steel was obtained at intervals during each day, by means of anapparatus shown in Fig, Fig. 13. DISTANCE instrument was mounted on the locomotive and connected to the front truck axle,connection with the wheel sliding indicator. It was used in 64. Observations were also taken of the atmospheric temperatureand of the relative humidity from the readings of an hygrometer whichconsisted of wet and dry bulb thermometers. 28
