    Observation 139 Dog. Sciatic. Divided and immediately sutured. 5 7no7iths, The changes in the proximal segment are similar to those already described in Observation 138. The distal segment shows new myelin sheaths both in longi- tudinal and in transverse section. Observation 140 Human ulnar. Thirteen months after division. Fibrous junction occurred. In sections above the level of the original division, the nerve appears normal, so far as its fibres are concerned, but interstitial connective tissue is in excess, as if from interstitial neuritis (possibly associated with the neuralgia for which the nerve was originally divided). At site of division.-—-There is a large end-bulb at the lower end of the proximal segment, formed as usual of interlacing neurilemma nuclei. The peripheral part of the nerve below shows longitudinal rows of neurilemma nuclei. No signs (with this stain) of new myelin are found. In sections ^-inch and i^-inch below level of division.—No myelin is seen with this stain. The nerve consists of closely packed rows of nuclei.
