upper and anterior part of the chest from the sternum to the shoulder; as also in the supra clavicular triangle. The more muscular branches from the third and fourth cervical go to the trapezius, levator anguli scapula, and rhomboidei muscles. To sum up the whole, in this region, then, the most marked neuralgic points are found, first, at the middle of the side of the ueck on the posterior border of the sterna cleido-mastoidcus, where these several up-running nerve trunks emerge to become super- ficial. Next, at the upper and lateral part of the sterno-cleido- mastoideus, just below its insertion, and about on a level with, but back of, the lower part of the ear, which is the point of the first superficial bifurcation of the occipitalis minor nerve. Next, we find a neuralgic point, a little above and back of that, a little outside of the first vertebra, which is the emergence of the trunk of the occipitalis major nerve. Next, a point in front of, or rather anterior, to that, and just a little back of the ear, where the electrode can be placed upon the posterior auricular branch; and then, again, a little lower down, on the middle of the upper portion of the sterno-cleido-mastoideus, where it rests upon the au- ricularis magnus, which is the great superficial ascending branch from the cervical plexus. Next is a neuralgic point on the anterior edge of the lower third of the trapezius muscle, at the point where the spinal accessory nerve gives off a large branch to the exter- nal surface of the trapezius, for there the nerve emerges, run- ning downward and backward over the lower part of the ex- panse of that muscle. Next, at and about the pavilion of the ear, and at the mastoid process; and, finally, at about the parietal protuberance. This latter is a neuralgic regional the peripheric distribution and anastomosis of two nerves. There is another such region of surface terminal ramification and anasto- mosis over and about the nucha, particularly about the three first vertebrae. There is another such over the trapezius, where is distributed the spinal accessory branch; and another over the upper and anterior part of the neck, and peculiarly so in the supra clavicular triangle. Indeed, the neuralgic region of peripheric distribution is a characteristic of all wide-spreading superficial nerves ; while neuralgic points appear to be limited
