After a vital fixation of a cat into which Orth's solution was infused through the aorta, the optic nerve was taken out, fixed with Orth's solution again, then with Miiller's solution and was cut into about 10 μ thick refrigerated cross sections which, given a myelin sheath staining, were included on an 100 μ. lattice-work graduated object glass with 5 % glycerin-gelatin solution Then the authors have speculated about the relationship between the myelin sheath and the axis cylinder under a microscope of 1,000 magnification. The results obtained were as follows. The percentage (a/d× 100=g) of the ratio of the diameter (a) of axis cylinder to that (d) of fiber is smaller in small fibers and larger in larger fibers the relative thickness of myelin sheath is greatest in small fibers, and tends to get smaller according as the fiber diameter is bigger, and it traces a line given by the expression y = 2.24x + 48.5. Futhermore, the ratio of the thickness (m) of axis cylinder to that (d) of fiber and the ratio of the area (A) of axis cylinder to that (M) of myelin sheath were observed to vary with similar tendencies.
