    [d) Half an inch below graft.—Numerous fine hair-like young sheaths are in process of formation, and between them can be distinguished the profoundly degenerated and faintly-staining remains of the old myelin sheaths. [e) Two, three, five, and six inches below graft.—Sections taken at all these levels show exactly similar appear- ances. Young myelin sheaths are more abundant and are more easily demonstrated near the surface of the nerve- trunk than deeper in towards its centre. Observation 29 Dog. Sciatic nerve. Divided and sutured immediately. 8 weeks. As usual the proximal segment shows continuity of normal with fine young myelin sheaths. These latter are well stained. At first, above the scar-tissue, they are arranged longitudinally, then in the locality of the scar in an irregular plexiform manner, and finally, on the distal side of the scar, longitudinally again. On the distal side, the young myelin sheaths are relatively more numerous in the superficial than in the central part of the tissue. The young sheaths are now quite long and stain deeply ; they have a sinuous course, and well-marked fusiform and moniliform thickenings occur on them at intervals (see Plate 3, fig. 12).
