“The meaning of the Urdar-fountain, that Thor is afraid to make boil, and the cause of his reluctance, will only be comprehended by our physicists when the reciprocal electro-magnetic relations of the innumerable members of the planetary system, now just suspected, shall be thoroughly determined. Glimpses of the truth are given in the recent scientific essays of Professors Mayer and Sterry Hunt.
The ancient philosophers believed that not only volcanos, but boiling springs were caused by concentrations of underground electric currents, and that this same cause produced mineral deposits of various natures, which form curative springs.
If it be objected that this fact is not distinctly stated by the ancient authors, who, in the opinion of our century were hardly acquainted with electricity, we may simply answer that not all the works embodying ancient wisdom are now extant among our scientists.
The clear and cool waters of Udar were required for the daily irrigation of the mystical mundane tree; and if they had been disturbed by Thor, or active electricity, they would have been converted into mineral springs unsuited for the purpose.
Such examples as the above will support the ancient claim of the philosophers that there is a logos in every mythos, or a ground-work of truth in every fiction.”
