Summary Simultaneous measurements of the vertical component and two perpendicular horizontal components of gravity have been made in the I. C. I. Salt Mine at Winsford (Cheshire) over the period 1951 April 16 to 24. Apart from the gravitational tide the measurements show a well‐developed influence of the variations in the maritime loading, especially in the horizontal components. A common drift in all components indicates the influence of meteorological pressure variations over a large area. Furthermore, diurnal variations of presumably meteorological origin have been observed. The “load tilt” has been determined. It is elliptical with an azimuth of N. 47° W. of the main axis and has an amplitude of 1.65 millisec per foot tide at Liverpool (5.5 millisec/m). The load influences in the vertical component are only 2.4 per cent of those in the horizontal direction and indicate the influence of more distant oceanic areas.
