The surface of this pulp tube preserves the same reticular character. If we adjust the focus to the fundus of the caverni invested by them, we find numerous transversely arranged fibres (c). These pas- sages are lined with flat, spindle-shaped cells (/), which, indeed, as the transverse section {b) teaches, have globular nuclei. We have once more before us a vascular endothelium ;.
