Abstract

Measurements are reported of the daily variations of meson intensity at Mawson, Antarctica (?=73 °S.), recorded by counter telescopes inclined at 45° to the vertical in each of north, east, south, and west directions. The results, together with those from a vertical telescope, are examined and found to be inconsistent with an assumed common origin of the different directional variations in the interaction of an anisotropic primary radiation with the Earth's dipole field.
