A short time ago, from an analysis of the registers of magnetic storms in different parts of the earth, Professor Chapman pro-dueed a tentative theory as to the process by which energy from the sun, generally regarded as the cause of these storms, could reach the earth." Professor Linuemann has made several objections to this theory, and the controversy provided the subject of recent discussion at the Geophysical Society's meeting at Burlington House.
Professor Chapman's original idea, since modified, was that a beam of ions, carrying electricity of one sign only, could be projected from the sun to the earth, or rather the outer atmosphere, and by bombardment of this enveloped so alter its magnetic charge as to cause a magnet disturbance in the earth.
