A magnet for removing particles of steel or iron from the eye. It consists of a number of magnetized steel rods, separated from each other, but in close proximity, and fitted at their ends with iron caps. One of these caps is provided with a delicate point of malleable iron, 32 mm. long, 1 mm. wide, and 0.3 mm. thick, which sustains with ease a weight of 225 grains.
