An instrument for measuring the distance which one has travelled on the road: an odometer or pedometer. "I went to see Colonel Blount who showed me the application of the waywiser to a coach, exactly measuring the miles, and showing them by an index as we went on. It had 3 circles, one pointing to the number of rods, another to the miles, by 10 to 1000, with all the subdivisions of quarters."-Evelyn.
