Abstract
THE research described in the report before us was undertaken at the instigation of the Iron Ores Committee of the Conjoint Board of Scientific Societies. Certain lines and centres of magnetic disturbance had been noted in Britain so long ago as 1890 by Rücker and Thorpe, and a new magnetic survey by Mr. G. W. Walker in the years 1914 and 1915 confirmed the existence of these disturbed areas. It is well known that iron is the only element which gives rise to magnetic effects of considerable intensity, and it was therefore of importance to determine whether any relationship could be established between the location of these disturbances and the distribution of iron ores.
