Note 24 — CHAPTER 6 PROOF THAT ELECTRONS ARE ATOMS OF ELECTRICITY
Reading edition
It seems that this phenomenon had previously been observed by M. Fievez. (Cf. Michelson, Dr. Albert A., “Light Waves and Their Uses,” Page 107.) “He thought that each separate line was doubled or quadrupled.” Lockyer, in 1866, observed that some of the lines in a sun spot spectrum were widened. Prof. Charles Young and W. M. Mitchell observed that some of the lines were even double, but it was not suspected that these phenomena were caused by a strong magnetic field in sun-spots, brought about by free electrons being driven around in a vortex movement. In fact, Mitchell referred to the doublets as “reversals.”
