It appears that four days before, he had been blown up three times by aero torpedo mortar shells while attending the wounded. One had blown him into the air, another had blown him into a dug-out, and a third had knocked him down. Two or three hours later, having finished the job of carrying wounded to the dressing station, everything seemed to “go black” in the dug-out where he was resting, and from that time on he had been shaky. It seemed that he had hardly slept for several days before he finally gave in. There were irregular spasmodic movements of the head, arms (especially the right), and legs (especially the left). There were coarse tremors and incoördination in moving the arms. With eyes closed, he touched his nose with uncertainty. Cotton-wool touch on arms or head provoked lively movements. “I was always ticklish,” he explained, “but never like this; I can’t stand it, Sir.” Pinpricks produced almost convulsions. There was perspiration, rigidity of legs, and spasm such that knee-jerks were unobtainable. Plantar reaction, flexor. There were also visual hallucinations of bursting shells, and these were also heard when dozing. Improvement followed with rest, but about two weeks later, on waking to find himself being carried back to his tent to avoid a shower, he was so terrified that a special nurse became necessary. He was still jumpy the next day, alarmed at footsteps, and afflicted with headache. He improved further in three days; remained two months in hospital in England, had one month’s leave, and then returned to light duty. Shell-shock; thrown against wall; comrades killed; no visible trauma, or loss of consciousness: Persistent TREMORS, augmented in intentional movements; CRISES of agitation following noise or emotion. =Case 224.= (MEIGE, February, 1916.) A corporal (an expert gunner) and his squad had just entered a mine shaft on Nouvron Plateau, January 13, 1915, when a shell, bursting above them, threw him violently against the wall and killed or wounded several of his comrades. The corporal himself was not wounded, nor is it clear that consciousness was lost. The man lay waiting on the ground for some time until a communication trench could be finished and he could be evacuated without much danger from the mine shaft. He had already begun to tremble, and trembled still more while going back in the trench.
