Nervous and mental diseases . the brain, and a hemor-rhagic cyst remains, with ascending and descending degenerations corre-sponding to the location of the lesion in the cross-section. A wide area ofmyelitis, containing a comparatively small and recent clot or hemorrhageinto a gliomatous growth, may be encountered as secondary accidents. Symptoms.—A primary focal hemorrhage into the cord is of rapid,usually of sudden onset The infiltration sort, being almost always sec-ondary, may be preceded by sensory and motor symptoms for hours,days, and even weeks. This is also true of the larger clot that formsin a softened myelitic territory, producing sudden exacerbation of theusually precedent paraplegic symptoms. The earliest symptom is com-monly one of severe pahis radiating in the body-segments correspond-ing to the hemorrhagic focus. These are due, presumably, to the pressureor laceration of the sensory tracts in or near the posterior pains occur in the limbs, girdling pains in the trunk that may.

Veryshortly—that is, in the course of a few minutes or an hour—after an acci-dent has occurred, and the patient has perhaps walked a short distance,paraplegic symptoms appear. These may be partially unilateral atfirst. The legs weaken, the patient gradually or quickly sink&down, and usually the motor loss is promptly established at itsmaximum. The condition that now develops depends on thelocation, extent, and size of the clot, and the amount of pressure itbrings to bear on the conduction tracts. Usually there is some im-provement, owing to the subsidence of the pressure and of the shockor insult to the adjacent portions of the cord. The developmentafter a day or t
