8 Waters from snow and ice are all bad. For, once frozen, water never recovers its original nature, but the clear, light, sweet part is separated out and disappears, while the muddiest and heaviest part remains. The following experiment will prove it. Pour by measure, in winter, water into a vessel and set it in the open, where it will freeze best; then on the next day bring it under cover, where the ice will melt best; if, when it is dissolved, you measure it again you will find it much diminished. This shows that freezing dries up and causes to disappear the lightest and finest part, not the heaviest and coarsest, to do which it has no power. In this way, therefore, I am of opinion that such waters, derived from snow or ice, and waters similar to these, are the worst for all purposes.
