If the upper palpebra is pushed loosely upward and backward with a suitable instrument1 which follows the curvature of the bulb while the person examined looks downward, in some instances easily distinguishable lines can be seen macroscopically under the conjunctiva. These lines, depending on the illumination, can usually be discerned best from the front, but sometimes they can be seen only from the side. In many instances they can be seen only in a dark room with focal lighting, but at times they are not visible even under these circumstances. In the dark room also they are best seen from the front, but at times they are visible only from the side. Their number is variable. From two to seven lines were noted in the eyes examined at the Hungarian State Hospital. The larger the number of the lines observed, the more evident does their meridional arrangement become. The
