“This first cigarette terminated, he prepared to make another, when we stepped up and began to interpose obstacles.... He searched vainly in his pocket for his tobacco, as we had filched it. He searched for it in another pocket, going through all his clothes until he came back to look for it in the first pocket, when his face expressed surprise. I offered him his tobacco-pouch, but he did not perceive it; I held it near his eyes, yet he still did not perceive it; even when I shook it just in front of his nose, he did not notice it. But when I placed it in contact with his hand, he seized it and completed his cigarette directly. Just as he was about to light his cigarette with one of his matches, I blew it out and offered him instead a lighted match which I held in my own hand; he did not perceive it; I brought it so close to his eyes as to singe a few lashes, yet he still did not perceive it, neither did he make the slightest motion of blinking.... _The patient sees certain objects and does not perceive others; his sense of sight receives impressions from all objects in personal relation with himself through the touch, and does not receive impressions, on the contrary, from things external to him; he perceives his own match, but does not perceive mine._” During the course of this observation the patient gave evidence that the memory of his former occupation as a professional singer had been revived.

At this moment the sun lit up with a bright ray a glass window that closed the lodge on the side towards the court.... This ray must have given him the impression of a footlight, for he at once placed himself before it, readjusted his toilet, opened the roll of paper which he carried in his hand, and softly hummed an air, running his eyes over the pages as he slowly turned them, and marking with his hand a measure that was perfectly rhythmical. Then he sang aloud, in a highly agreeable manner, giving his song the correct expression, a patriotic ballad to which we all listened with pleasure. This first selection terminated, he sang a second, and afterwards a third. We then saw him take out his handkerchief to wipe his face. I offered him a wine-glass of a strong
