Butthese are limited to thearms; and if the legssuffer it is in a differentway—as simple paraplegiawith excess of myotaticirritability that may goon to spasm. The prognosis of the disease in the simple anaesthetic form is graveonly when the sufferer is still exposed to fresh infection, or in cases ofconsiderable severity. But it must be remembered that, just as thedisease may develop long after exposure to its cause, so it may slowlyincrease for a long time after this exposure has ceased. The treatment of the affection is beyond the scope of this work; inso far as the nerve symptoms require special measures, these are thesame as in ordinary neuritis. A trial may be made of the stimula-tion of the muscles by whatever form of electricity they will respondto, and of the anaesthetic areas in the skin by the wire brush andfaradism. YOL. I. 11

PAET III.DISEASES OF THE SPINAL COED. INTRODUCTION. ANATOMY OF THE SPINAL COBB* The spinal cord, it will be remembered, is much shorter than thespinal canal, reaching only to the second lumbar vertebra. Hence thenerve-roots descend to their foramina of exit. The lower they arise,the longer is their intra-spinal course. All those below the secondlumbar pair leave the canal below the lowest portion of the cord. Itis customary to speak of the portion of the spinal cord from whicheach pair of nerves arise as the corresponding segment of the cord.The segments are longest in the dorsal region, and shortest in thelumbar enlargement. They are also called m
