ARRHENIUS, SVANTE.

Ueber die Ursache der Nordlichter.

(Stockholm, P.A. Norstedt, 1900). 8vo. In the printed wrappers. No. 5, 'Bihang till K. Svenska Vet.Akad. förhandlingar'. A very fine and clean copy. Pp. 545-580


First printing of Arrhenius's paper on northern lights (aurora). he auroral theory was based on radiation pressure of electromagnetic waves and eruptions from the sun. He proposed that during great eruptions on the sun, large quantities of matter, in the form of droplets or dust, are ejected in a radial direction from the sunspots and are pushed out from the sun by radiation pressure. With this theory Arrhenius could explain the high correlation existing between occurence of the northern lights and sunspot activity.
