Summary A re‐examination of the gravity values relative to Cambridge at the primary stations York, Newcastle‐upon‐Tyne, Edinburgh and Aberdeen has shown that the errors of the pendulum observations (Browne et al. 1950) at these places, with the exception of Newcastle, are well within the published standard deviations, while the error at Newcastle only just exceeds twice the published standard deviation. The calibration factor of the gravity meter used in the investigation has been found by comparison with the pendulum values to be consistent with the tilt‐table value determined by the maker. The new measurements suggest that the uncertainties given by Cook (1953) in his adjustment are realistic. By combining the present observations with the pendulum values and the differences measured by Bullerwell (1952) new gravity values have been calculated for the four stations.
