Odometer made by John Dollond and used to measure the length of a route. A wheel pivoting on a handle is pushed by hand. Its rotating motion is transmitted to a pair of pointers that show the distance traveled on a quadrant with three scales (miles - poles - yards). Ten revolutions of the wheel correspond to about 27 yards (25 meters). Provenance: Lorraine collections.
