The outlines of the inner fibers are somewhat less distinct than in the preceding stage, and some of the bundles seem to be splitting up. This condition is represented in Fig. 2. Most significant is the fact that at no stage is any karyokinesis found among the muscle fibers, although the increase in the number of nuclei is enormous. Passing through Region II of this stage, the number of old fibers decreases and the scattered nuclei increase, until at the. FIG. 2. plane

Passing through Region II of this stage, the number of old fibers decreases and the scattered nuclei increase, until at the. FIG. 2. plane where the cut was made all old fibers disappear and we reach Region III, which is made up entirely of closely crowded nuclei, each surrounded by a small amount of protoplasm. Karyokinesis is first seen in II, a short distance above the cut, among the outer cells, never in t/ie muscle fibers, and the num- ber of dividing cells increases toward the growing tip until it becomes quite large. In the fifth stage a further difference is to be noted. We find in Region I, in the inner part of the limb, the old muscle.
