A British soldier, aged 27, showed a somewhat remarkable phenomenon. It appears that at five years of age, this man had had poliomyelitis, affecting the left leg. At 20 years of age, he had had pneumonia, and this had been followed by a paralysis of the right arm and leg with a loss of speech. The man recovered from this illness, although he never quite regained full control of the right hand. It is evident that this lack of control was not marked, else the man would not have been enlisted, and it is Dr. Batten’s opinion that at all events he could not have shown pathological movements of the right hand at the time of enlistment. However this may be, in October, 1914, the soldier was struck on the right shoulder with shrapnel. Apparently he was not wounded, but thereafter he was not able to use the right arm well, and in two months’ time he had become unable to manipulate his rifle. On January 13, 1915, he was sent home. The remnants of the old poliomyelitis of the left leg were shown in a general weakness of that leg as compared with the right. _The movements of the right hand were those seen in athetosis._ The movements were independent of volition. The patient had difficulty in releasing his grasp. He improved rapidly during the six weeks he was in hospital, although the movements of the right hand never became entirely normal. In this case, according to Batten, “the stress was sufficient to bring into prominence the symptoms due to an old cerebral lesion.” Hysterical versus thalamic hemianesthesia. =Case 114.= (LÉRI, October, 1916.) A soldier, 40, had been suffering for a number of months with pains in the left side of the trunk and feelings of weakness in the left arm and leg. In the summer of 1915 he was on leave and while walking, fell, lay down, and found he could hardly move his left arm and leg. Two or three weeks later he got up, walking with a stick. After some time in hospital, he was sent back to the trenches, a little weak. He had shortly, however, to be examined neurologically again. He could hardly raise the left leg and his passive resistance was poor on this side. The left side was almost completely anesthetic to all forms of stimulus, although an intense faradic current yielded a feeling like that of a fly. Nor was the tactile sensation absolutely nil, as it could be got with a flat finger on the upper arm and thigh. Cold and heat sensations not well localized. The hemianesthesia was sharply limited at the median line and affected the buccal, lingual and nasal mucosa. Deep sensibility was almost abolished on the left side. Stereognostic sense was lost and the sense of position was lost absolutely for hand and foot.
