For every stone is nothing else but a congealed lump of frozen earth, though some more or less than others; and therefore it is no absurdity to say that stones and lead, by reflecting the air, increase the coldness of the water.
QUESTION VI WHAT IS THE REASON THAT MEN PRESERVE SNOW BY COVERING IT WITH CHAFF AND CLOTHS?
A GUEST, PLUTARCH.
Then the stranger, after he had made a little pause, said: Men in love are ambitious to be in company with their sweethearts; when that is denied them, they desire at least to talk of them.

This is my case in relation to snow; and, because I cannot have it at present, I am desirous to learn the reason why it is commonly preserved by the hottest things.

For, when covered with chaff and cloth that has never been at the fuller's, it is preserved a long time.

Now it is strange that the coldest things should be preserved by the hottest.
Yes, said I, it is a very strange thing, if true.

But it is not so; and we cozen ourselves by presently concluding a thing to be hot if it have a faculty of causing heat, when as yet we see that the same garment causes heat in winter, and cold in summer.
