October 26, the myelin sheath of a single tnyelinated fiber ends at the point indicated by the arrow. The sheath cell, A', is associated with the final myelin segment. The sheath cell, Q, is on the accompanying untnyclinated nerve. The most peripheral sheath cell on the nerve is shown at .V. 1 'i tober 30, S divides once, giving rise to S\ and SI and the latter daughter cell divides giving rise to S2a and S2b. November 3, two new myelin segments are formed, one associated with S\ and tin ' itIKT with S2a. November 8, the new segments grow somewhat both in length and in diameter and in thickness of the myelin sheath. This region was kept under observation for more than two months longer. During tlm period the animal was subjected to partial starvation and no further essential gn \\tli changes took place. Finally, on January 18, the myelin segment associated with S2a suffered degeneration, possibly as an indirect result of mal- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
