We find that one turn in 20 minutes, which is the rate given by the smaller wheel w, is a con- venient speed. When a plant is fixed into the box B it naturally happens that the centre of gravity of the plant and flower- pot does not coincide with the spindle, so that the clock has varying amounts of work to do in different parts of the rotation. The Cambridge Scientific Instrument Co.'s kliaostat has an arrangement by which the position of the weight can be altered until its centre of gravity is at the centre of rotation.
