    The specimen was obtained ten days later. In the proxi?nal segment of the nerve, degeneration of the larger myelin sheaths is evident in the vicinity of the cut end. Leashes of new myelin sheaths are seen amongst the old, but they do not yet extend downwards beyond the limits of the old. The graft itself is markedly degenerated, the myelin being broken up into globular masses taking the stain faintly. In the distal part of the nerve fine hair-like young sheaths can be detected in places, running longitudinally amongst the old (compare Observation 26). Observation 35 Monkey. Sciatic nerve. Divided, not sutured. 5 mofit/is. The proximal segment terminates in a well-marked bulb formed of numerous leashes of young myelin sheaths coiled, intertwined, and bound together by fibrous tissue. The sheaths at the lowest part of the bulb run almost transversely to the long axis of the nerve. In the distal segment of the nerve young myelin sheaths can be detected amongst the degenerated remains of the old. A pad of muscle lies between the proximal a7id distal segments.
