    10. The inner wall of the optic canal lies against the posterior othmoidal cell of that side. Figure 12 illustrates this relationship in sagittal section, on the left side. The nerve is shown at its entry into the optic canal. The canal runs in the outer wall of the cell for a distance of 6 millimetres, and to demonstrate this the wall of the canal has been opened up. 11. The floor of the optic canal is formed on the one side by the roof of the posterior ethmoidal cell. 2 1 Fig. 13.—Natural Size. r. Optic nerve. 5. Superior turbinal. 2. Internal carotid artery. 6.

Figure 13 illustrates, in sagittal section, the course of the left optic nerve for a distance of. 7 milli- metres, as it passes above the posterior ethmoidal cell. Its bon}^ covering has been removed. 12. On both sides the inner and lower walls of the optic canals, as well as the whole optic sulcus, are formed by the walls of the posterior ethmoidal cells. In Figure 14 (Atlas) this relationship is shown, and also in a corre-
