Paper, 'On local magnetic disturbance in Islands situated far from a continent' by E W [Ettrick William] Creak

Description

Creak writes: 'It has been known for many years past that in the islands of St. Helena and Ascension observations of the three magnetic elements made at different stations gave remarkably divergent results, caused by some undefined local magnetic attraction. Thus in the observations at St. Helena, carried out under the auspices of the British Government in 1840-46, it was found that the observed inclination and intensity differed considerably at the two stations of Longwood and Sister’s Walk, 2½ miles apart, and these again differed from those made on board ships in the anchorage.'
