Abstract
AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down motion of a body moving freely under gravity, and the uncertainty of the result is considerably less than that of any previous measurement.
