Question IV. WHAT IS THE REASON THAT A BUCKET OF WATER DRAWN OUT OF A WELL, IF IT STANDS ALL NIGHT IN THE AIR THAT IS IN THE WELL, IS MORE COLD IN THE MORNING THAN THE REST OF THE WATER? A GUEST, PLUTARCH, AND OTHERS. ONE of the strangers at the table, who took wonderful great delight in drinking of cold water, had some brought to him by the servants, cooled after this manner; they had hung in the well a bucket full of the same water, so that it could not touch the sides of the well, and there let it remain all night: the next day, when it was brought to table, it was colder than the water that was new-drawn. Now this gentleman was an indifferent good scholar, and therefore told the company he had learned this from Aristotle, who gives the reason of it. The reason which he assigned was this. All water, when it hath been once hot, is afterwards more cold; as that which is prepared for kings, when it hath boiled a good while upon the fire, is afterwards put into a vessel set round with snow, and so made cooler; just as we find our bodies more cool after we have bathed, because the body, after a short relaxation from heat, is rarefied and more porous, and therefore so much the more fitted to receive a larger quantity of air, which causes the alteration. Therefore the water, when it is drawn out of the well, being first warmed in the air, grows presently cold.
