The sixth volume in the series consists of Sophus Tromholt's monograph Under Nordlysets Straaler, first published in Danish in 1885 and then in a slightly different English version (Under the Rays of the Aurora Borealis, in two vols.) later in the same year. Both editions are included here. They are introduced by a biographical essay and summaries of contents by Kira Moss from UiT The Arctic University of Norway.
