The perineurium, or sheath covering the bundles of nerve fibers, was at least three times as thick in the non-masséed side, and the connective tissue around the perineurium was also thickened with numerous new-formed cells.

In Fig. 4 all the nerve elements arc of normal appearance, while the nerve elements from the non-masséed side—Fig. 3—show that the perineurium is thickened, and underneath this there are deposits of new-formed connective tissue which crowd and compress the nerve fibers.
