Ten months after the traumatism, the hemiplegia and spastic walk remained. The upper limb was now carried in extension back of the body, with hand supinated, fingers sometimes in extension, sometimes in flexion, index finger separately from the others. Finger movements difficult and shoulder movements limited. The leg, however, was almost normal except that the toes could not be moved. The tendon reflexes were more lively and cloniform on the right, but there was no longer patellar or ankle clonus. Stereognosis slow, but finger movements were naturally difficult. W. R. of blood, negative. Probably this is an organic case. Blown up by a shell; no skin or bone lesion: Mixture of organic (_e.g._, lost knee-jerks) and functional (_e.g._, urinary retention) disorders. =Case 214.= (CLAUDE and LHERMITTE, October, 1915.) A man, 38, was blown up in a trench without sustaining skin or skeletal lesions, April 5, 1915. He lost consciousness for a half hour and, coming to, found a crural paraplegia and urinary retention. Examined July 24, in addition to the paraplegia were found tactile and algesic hypesthesia of the legs with preservation of deep sensibility. Pains were felt in the legs, especially in the hips. The knee-jerks were abolished; the Achilles jerks were preserved, as well as the flexor plantar reflexes and somewhat weakened cremasteric and abdominal reflexes. Micturition was difficult. Constipation. Slight paresis of left arm. Lumbar puncture, July 28, yielded a clear fluid of normal tension without chemical or cytological changes. The sphincter disorders gradually disappeared. The knee-jerks reappeared in a weakened form August 31. The legs could, at the time of report, be moved somewhat, though not above the level of the bed. We here deal, presumably, with a mild form of concussion of the spinal cord, in which, however, some of the transient symptoms are very possibly merely functional in origin.
