The man was slenderly built, of medium height, in moderate nutrition; pale of face and mucosae; pulse small, regular, and 114. Neurologically, the deep reflexes were generally increased, and the skin reflexes decreased. Percussion on the back of the head elicited marked pain. There were no pressure points. The movements of the arms were free; there was a marked tremor of both hands, more marked on the right. The left grasp was 45, the right, 20, by the dynamometer. When lying upon his back, the patient could move his legs, but he moved them only slowly and with tremor. The heel-to-knee test was successfully executed despite the tremor; nor could it be demonstrated that there was a genuine ataxia. Placed upon his feet, he would collapse, nor could he be made to walk at all. With trunk supported, he was able to make only a few unsuccessful attempts to drag the feet forward. Associated with this apparent paralysis, the sensitiveness to touch had entirely ceased in the legs, as well as sensitiveness to pain. The zone of analgesia, however, was more extensive than the anesthesia, spreading upwards three or four cm. farther in front. Ticking of the watch could not be heard even at the meatus of the right ear, although hearing of the left ear was entirely normal; bone transmission on the left side. Whispers could be heard close to the meatus. On speaking, the patient stammered in starting sentences. He looked extremely anxious during the first few days in the Jena wards, claiming that he could not raise himself. When his trunk was raised, he would let himself sink feebly back into dorsal decubitus. However, when believing himself unobserved, he was found to be able to move himself in bed somewhat quickly. He was able to get a box from beneath the bed, to open the drawer of the night-stand, and to take remarkable care of his moustachios. He complained more and more of headache, though his appetite and sleep were good. He was often irritable. Treatment at first consisted of cold packs of the legs twice a day, salt-water baths, active and passive exercises of the legs in the position of dorsal decubitus. The patient declaimed against this treatment. There was slight improvement after a week of treatment. He was then able to raise himself in bed, seat himself on the edge of the bed, and stand without support, all the time, however, groaning and moaning. After a few moments, he would fall back on the bed, complaining of violent headache and dizziness. While standing, both legs trembled.
