A Russian private was buried after a shell explosion, September 13, 1915, head down, so that only his legs stuck out of the débris. Afterward his right hand refused to move, and there was edema of the right wrist, with pain referred to the shoulder joint. The head shook and made jerky movements during the day, but ceased them in sleep. Speech was retarded; words were uttered clearly enough but in a sing-song fashion; sometimes the man stammered. Hearing was diminished in the right ear. Pupillary responses were lively, but the swallowing reflexes were diminished, and the corneal and conjunctival reflexes were absent. The tendon reflexes were lively on both sides. There were no pathological reflexes. At the end of October--six weeks later--the patient was sent home on convalescence for three months, and improved rapidly after a short time in family surroundings. He was examined again, two months after discharge, and found normal in all respects. He returned to the ranks. _Re_ Shell-shock in Russians, Arinstein concludes that concussion hysteria may occur in a perfectly normal person, yet be innocent of all organic signs indicating destruction of peripheral or central neurones. Rifle or machine-gun fire had not in his experience brought about concussion hysteria, which was invariably due to the bursting of a large projectile. With reference to Schuster’s remark that a sleeping man never acquires hysteria from the bursting of a shell near by, Arinstein confirms Schuster, finding amongst 2000 cases no instance in a soldier sleeping at the time the shell burst. _Re_ effects of cannonading, Gerver reports Russian instances of a kind of hysterical _clavus_, or sensation of a nail being driven into the back of the head, in men who have been a number of days under stiff shelling. Multiple wounds and bullet wound of palm: ACROPARALYSIS. Cure, five months. =Case 250.= (ROUSSY AND LHERMITTE, 1917.) A patient was observed at Villejuif, February 5, 1915. He had been wounded, January 2, 1915, and showed scars of a bayonet wound on the anterior surface of the right thigh, of a lance wound on the dorsal surface of the right foot, and of a bullet wound in the palm of the left hand. There was left wrist drop with fingers extended. On the sensory side, there was a glove anesthesia and analgesia up to the bend of the elbow. The right leg showed a paresis and contracture, but there were no sensory disorders in the legs. Reflexes were normal. The patient was discharged cured, in May, 1915 (psychoelectric method). This is an example of the so-called acroparalyses, paralyses limited to the hand or foot, many of which have developed in this war, after grazing wounds or more severe injury. More rarely they appear as if spontaneously. Sometimes they are preceded by slight arthralgia or vague pains.
