During his eleven months captivity at Grafenwöhr, Eschbach and Lacaze had the opportunity of observing the case of a soldier, 24, who sustained a shell-wound in the left lung and was made prisoner August 20, 1914, at Chateau Salins. He got well of his wound, but February 16, 1915, began to cry out and was restless in the night. He was found on the straw muttering words among which only the word, “Head, head,” could be distinguished. He was irresponsive, possibly deaf. Suddenly he had a convulsive crisis and whenever touched he would have jactitations and cry out. Otherwise, he was calm and stuporous. The pupils were widely dilated. In short, he showed a mental confusion associated with paroxysmal excitement due to cerebral and cutaneous hyperesthesia. The first symptoms had occurred the morning before, when he leaned his head against a wall and complained. Lumbar puncture yielded intra- and extracellular meningococci. The patient was isolated. In the afternoon he became less agitated, kept his eyes closed, mumbled, repeated gestures, would spit in his hands, rub his hands together, rub his neck, shoulders and body, or else he would pass his hands over his forehead and through his hair. Occasionally he would seize the straw and draw it to him with all his strength. Once when asked, “What is your name?” he said, “Not true. Not true.” Hallucinations appeared to have been added to the situation. The neck was a little stiff to forced flexion. Temperature 37.8. Lumbar puncture under chloroform anesthesia; antimeningococcus serum was injected. Next day quieter; able to get up and walk. Slept, mumbled less, was able to answer simple questions, desired to urinate and finally succeeded.
