26 Ocu. 3, Obj. 2mm. From a cross section of the proximal stump on the 
thirty-fourth day showing the increase in the number of non-medullated fibers ; 
a, bundle of non-medullated fibers; 6, medullated fiber. 
27 Ocu. 3, Obj. 2 mm. Bundles of new axons in the scar on the twenty-fifth 
day; a branching fibers; c, toward the center; p, toward the periphery. 
28 Ocu. 3, Obj. 7. Five protoplasmic bands, down one of which a new axon 
is growing. From the distal stump thirty-four days after the operation; c, 
{toward the center; p, toward the periphery. 
29 Ocu.3,Obj.2.mm. Cross section of the distal stump on the thirty-fourth 
day; a, protoplasmic band from a medullated fiber containing five new axons; 
h, bundles of protoplasmic bands from non-medullated fibers some of which con- 
tain new axons; c, droplet of meylin in a protoplasmic band.
