Then the Empress enquired of them the reason, Why Springs were not as salt as the Sea is? also, why some did ebb and flow? To which it was answered, That the ebbing and flowing of some Springs, was caused by hollow Caverns within the Earth, where the Seawater crowding thorow, did thrust forward, and drew backward the Spring-water, according to its own way of ebbing and flowing; but others said, That it proceeded from a small proportion of saline and acid particles, which the Spring-water imbibed from the Earth; and although it was not so much as to be perceived by the sense of Taste; yet it was enough to cause an ebbing and flowing-motion. And as for the Spring- water being fresh, they gave, according to their Observation, this following reason: There is, said they, a certain heat within the Bowels of the Earth, proceeding from its swift circular motion, upon its own axe, which heat distills the rarest parts of the Earth into a fresh and insipid water, which water being through the pores of the Earth, conveighed into a place where it may break forth without resistance or obstruction, causes Springs and Fountains; and these distilled Waters within the Earth, do nourish and refresh the grosser and drier parts thereof. This Relation confirmed the Empress in the opinion concerning the motion of the Earth, and the fixedness of the Sun, as the Bird-men had informed her; and then she asked the Worm-men, whether Minerals and Vegetables were generated by the same heat that is within the Bowels of the Earth? To which they could give her no positive answer; onely this they affirmed, That heat and cold were not the primary producing causes of either Vegetables or Minerals, or other sorts of Creatures, but onely effects; and to prove this our assertion, said they, we have observed, that by change of some sorts of Corporeal motions, that which is now hot, will become cold; and what is now cold, will grow hot; but the hottest place of all, we find to be the Center of the Earth: Neither do we observe, that the Torrid Zone does contain so much Gold and Silver as the Temperate; nor is there great store of Iron and Lead wheresoever there is Gold; for these Metals are most found in colder Climates towards either of the Poles. This Observation, the Empress commanded them to confer with her Chymists, the Ape-men; to let them know that Gold was not produced by a violent, but a temperate degree of heat. She asked further, Whether Gold could not be made by Art? They answered, That they could not certainly tell her Majesty, but if it was possible to be done, they thought Tin, Lead, Brass, Iron and Silver, to be the fittest Metals for such an Artificial Transmutation. Then she asked them, Whether Art could produce Iron, Tin, Lead, or Silver? They answered, Not, in their opinion. Then I perceive, replyed the Empress, that your judgments are very irregular, since you believe that Gold, which is so fixt a Metal, that nothing has been found
