A BAROMETER IN A TEA-CUP.
Senor Sauvogeon, of Valentia, has observed during long years the appearances presenting themselves in a cup of coffee when sugar has been added to it. It is well known that if the sugar is permitted to dissolve itself without being stirred, air bubbles appear on the surface of the liquid. If this frothy substance remains in the middle of the cup, lasting fine weather may be counted upon ; if the froth fixes itself in form of a ring on the sides of the vessel, there will be heavy rains ; if it remains between the sides of the vessel and the middle, the weather will be variable; and if the froth flows to one point in the circumference of the cup without dividing itself, there will be moderate rains. Senor Sauvogeon has compared these appearances regularly with the barometer and thermometer, and has not published them until after he had satisfied himself of their exact coincidence.
