Water Colder Than Ice

Put a lump of ice into an equal quantity of water, heated to 176
degrees, the result will be, that the fluid will be no hotter than
water just beginning to freeze; but if a little sea salt be added to
the water, and it be heated only to 166 or 170, a fluid will be
produced colder than the ice was at first.
