The presence of magnetic fields in all sun-spots and the spectroscopic observations of Evershed and St. John on the revolution of the spot vapors at various levels, seem to prove beyond doubt that sun-spots are vortices. The object of the present paper is to describe some recent experiments bearing on the suggested explanation of double or multiple spots, and the flocculi associated with them
