This is most readily demonstrated in the nucleus of the ganglionic cells have some of them entirely disappeared, while others aregreatly atrophied. The connective tissue is increased in amount, and the wallsof the blood vessels traversing the nucleus are thickened. In the earlier stagesthere are often many cells which contain granules of fat. The same changes,though perhaps less pronounced, are exhibited by the common nucleus of thevagus and accessorius, that of the facial, and sometimes also that of the glosso-pharyngeal nerve. The other nuclei are perfectly normal. We never find adiffuse inflammation, but in every case a priuuiry degeneration of thenuclei, w
