But the Empress, seeing they could not agree concerning the cause of Wind, asked, Whether they could tell how Snow was made? To which they answered That according to their observation, Snow was made by a commixture of Water, and some certain extract of the Element of Fire that is under the Moon; a small portion of which extract, being mixed with Water, and beaten by Air or Wind, made a white Froth called Snow; which being after some while dissolved by the heat of the same spirit, turned to Water again. This observation amazed the Empress very much; for she had hitherto believed, That Snow was made by cold motions, and not by such an agitation or beating of a fiery extract upon water: Nor could she be perswaded to believe it until the Fish- or Mear-men had delivered their observation upon the making of Ice, which, they said, was not produced, as some hitherto conceived, by the motion of the Air, raking the Superficies of the Earth, but by some strong saline vapour arising out of the Seas, which condensed Water into Ice; and the more quantity there was of that vapour, the greater were the Mountains of Precipices of Ice; but the reason that it did not so much freeze in the Torrid Zone, or under the Ecliptick, as near or under the Poles, was, that this vapour in those places being drawn up by the Sun-beams into the middle Region of the Air, was onely condensed into Water, and fell down in showres of Rain; when as, under the Poles, the heat of the Sun being not so vehement, the same vapour had no force or power to rise so high, and therefore caused so much Ice, by ascending and acting onely upon the surface of water. This Relation confirmed partly the observation of the Bird-men concerning the cause of Snow; but since they had made mention that that same extract, which by its commixture with Water made Snow, proceeded from the Element of Fire, that is under the Moon: The Emperess asked them, of what nature that Elementary Fire was; whether it was like ordinary Fire here upon Earth, or such a Fire as is within the bowels of the Earth, and as the famous Mountains Vesuvius and Ætna do burn withal; or whether it was such a sort of fire, as is found in flints, &c. They answered, That the Elementary Fire, which is underneath the Sun, was not so solid as any of those mentioned fires; because it had no solid fuel to feed on; but yet it was much like the flame of ordinary fire, onely somewhat more thin and fluid; for Flame, said they, is nothing else but the airy part of a fired Body.
