Following out the line of thought of a previous essay on the same topic, Sattler repeats that where the optic nerve passes through the sclera the latter exhibits an unusual course and arrangement of the elastic fibres. The margin of the scleral aperture contains exclusively circular fibres, of which a very large number radiate outward into the framework of the lamina cribrosa, and collectively pass along in the plane of the scleral aperture. Around the central vessels is placed a sheath extremely rich in elastic fibres, and being in intimate connection with the trabecles of the lamina. No elastic fibres run in the direction of the optic-nerve fibre-bundles.
