"If we suppose the sun and fixed stars to be gigantic
fountains of magnetic influence, acting upon our globe and
its atmosphere, and likewise upon all the other planets, the
phenomena of the universe would then become susceptible of
the grandest and simplest interpretations."--CROSSLAND.

"Are not the sun and fixed stars great earths vehemently
hot?"--NEWTON.

"Herschel's fixed idea was that the darkness of a spot upon
the sun was an indication of a cool and habitable
globe."--HUMBOLDT.

"The sun as the main source of light and heat must be able
to call forth and animate magnetic forces on our
planet."--_Ibid._
