This paper, after a short introduction upon previous publications and experiences, describes in a plain and practical manner four steps of improvement recently made in the centrifugal governor of an equatorial driving clock; and touches on

1. The number of the pendulums;

2. Their weight and momentum;

3. Their chronometric principle; and

4. The intensification of the effect of gravity upon them, chiefly to increase the promptitude and energy of the centrifugal action.
