His memory grew better from his arrival at a hospital in the rear in April. An attempt was made to remove the bullet in May, 1915. Though the surgeon’s finger was pushed as far as the tentorium the patient did not lose consciousness or sight, but on leaving the operating room he fainted and, after a few days of restlessness and delirium, he became completely blind. There was a cerebral hernia difficult to reduce. Vision became a little better and light and persons could be distinguished at the time when he was retired. A month after the operation there was a convulsive crisis beginning in the left arm, affecting the legs and ending in unconsciousness. Several similar crises occurred in August, sometimes with and sometimes without loss of consciousness. Later these crises began to be limited to the left side and then to be ushered in by visual hallucinations. At home he was unable to care for, clothe or feed himself. The crises became more frequent. The visual hallucinations began to dominate. This situation lasted to February, 1916, when the blindness which had been increasing since the onset of the hallucinations became complete. The crises now became less frequent and intense. Headaches not severe were exaggerated after seizures. The patient acted like a totally blind person and said that he had before him a uniform and constant gray without any light or dark spots or any color. Upon this background bizarre pictures, caricatures, disguised persons, animals or nameless things appeared colorless without relief, in silhouette, but highly suggestive of reality to such a degree that at first, according to the patient, he had made gestures to reach, or push aside these pictures. The crises were Jacksonian. Pallor, perspiration, shivering, irresponsiveness, clonic spasms of left arm followed. The patient always had a premonition permitting him to get into bed if he was sitting, for example, in his chair. Sometimes there was a dizzy sensation as if the body were being rotated to the left. This sensation did not occur at the beginning of the seizure and the patient fought against it, turning to the right. Sometimes he felt as if he were sliding at great speed down an inclined plane. Headaches and sleepiness followed, but there was never any complete loss of consciousness of memory.
