Summary. Data from eighteen Gough—Reitzel magnetometers and four flux‐gate magnetometers, which were operated in North Scotland, are presented and discussed. The coverage given by this set of instruments was not dense enough to resolve satisfactorily the complex induction anomalies in this area but some of the major features seen are described. The features observed cannot be accounted for either by oceanic induction effects or by source field effects. The Great Glen shows up as a major conductivity feature. Other effects are also observed, some apparently associated with the highly resistive granites found in this area.
