Not illustrated. 1921 Excerpt: ...vortex at a distance of 149 million kilometres. So far as we know, only a strong magnetic field can resolve a single line into a doublet, having components circularly polarised in opposite directions. Are we not compelled, then, to admit that where these unique and characteristic phenomena are present a magnetic field must be their cause? The evidence is of the same nature (but still more convincing by the unique character of the polarisations) as that for motion in the line of sight from the Doppler displacement of spectral lines in the case of moving stars or molecules. The absence of any shift of the red telluric lines by the rotation of the nicol, or of measurable displacements of the cyanogen flutings, as reported by Prof. Hale, considerably strengthens the argument and excludes instrumental and other errors. A quantitative comparison of the magnetic separations of the iron bines as observed in the laboratory and in the sun will be necessary to complete the argument and to make it, if full correspondence exists, almost insuperable. A small probability, of course, must be left open that under the conditions existing in the solar furnace, dissociation processes or something of the kind (lockyer) occur, so as to alter the whole vibrating system of the atoms and therefore also the relative separations of the different lines. Being in the country I unfortunately cannot supply now the magnetic separations of the region of Prof. Hale's photograph. The iron spectrum in the magnetic field has been examined by Becqitirel and Deslandres, Reese, Kent and Hartmann (Thesis, Halle, 1907), but the lines investigated are not far enough in the red. Recently Miss Van Meurs made in the Amsterdam laboratory a rather extensive study of the radiation of iron in the magnetic ...
