As this figure was drawn for the purpose only of showing how the outer wall projects into the hollow of the inner wall, no special references are needed to the other parts, which, by comparison with fig. 6, explain themselves. Fig. 8. Considerably older than figs. 6 and 7, showing the prolongation of the horn-like sheath over the disc, and the broad radiating tubes. FiK.
