The ivory point in a Fortin barometer is a short (typically about 1 cm) conically-shaped piece of ivory positioned with its apex pointing vertically downwards just above the surface of the mercury in the barometer's reservoir. It is positioned accurately during manufacture so that the tip of the ivory is in exactly the same horizontal plane as the zero mark of the scale which measures the height of the mercury column, and is known as the Fiducial Point. Before reading the height of the mercury column, a user of the baromerter adjusts the level of mercury in the reservoir until its surface just touches the ivory point, at which level the height scale will give an accurate reading.
