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 persuaded 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 had 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 ecliptic, as near or under the poles, was, that this vapour in those places being drawn up by the sunbeams into the middle region of the air, was only condensed into water, and fell down in showers 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 only upon the surface of water.
