In another case chloroformed 17 months after recovery from tetanus no such phenomena appeared. It would seem that the impregnation with tetanic virus or toxin must last in the nervous system a good deal longer than the apparent disease clinically lasts, but that this belated and concealed intoxication eventually passes. The phenomena are perhaps _analogous to_ those of _Babinski and Froment’s_ so-called post-traumatic physiopathic or _reflex phenomena_. It was following the special work of Babinski and Froment upon the use of chloroform anesthesia in detecting physiopathic conditions that Monier-Vinard made his observations in cases of tetanus. Shell-shock from falling of shell at a distance: Hysterical hemiplegia, terminating in brachial monoplegia. Case to show that the reflex or physiopathic disorders of Babinski and Froment may occur without mechanical injury in the region involved. =Case 281.= (FERRAND, June, 1917.) A soldier of the class of 1917 who never went to the front, while in training at Belfort, felt violent emotion on the occasion of the falling of a big shell in the town of Belfort. The explosion was a good distance from him. He lost consciousness a few moments, February 23, 1917, and almost at once found himself unable to move his left side. He was hemiplegic three months, but his leg shortly regained power. December 23 he entered a neurological center with his arm flaccid and a paralysis affecting the shoulder also. There was an almost complete anesthesia of the arm terminating in segmentary fashion about the shoulder, and the whole of the left side was slightly hypesthetic, although there was no disorder of motion except in the arm. The tendon reflexes of the left arm were exaggerated, and there was even contracture upon percussion of the muscles themselves. Percussion of the thenar and hypothenar eminences produced movements of the hand. There were several vasomotor disorders. Percussion led to large vasomotor plaques, and rubbing of the skin produced a reddening which passed away slowly. The hand was red and cold. Slight electrical hyperexcitability of flexors with feeble galvanic current; excitation of the extensors not associated with any contractions of the antagonist muscles. Threshold lower for flexors on the affected side in the forearm. Half centimeter atrophy of the biceps. The forearm and hand were possibly slightly increased in volume from a blue edema of the dorsal surfaces. The man was very timid, complained little, and accepted all treatment, which, however, was not very effective. This is presented by Ferrand as a case with physiopathic disorder in the sense of Babinski and Froment, though it does not present any sign of organic lesion whatever. Shell fire: Delayed shell-shock symptoms, sub-lethal, appearing in England. =Case 282.= (MCWALTER, April, 1916.)
