I was puzzled by this last speech of his. Was the brain really affected? Had I to do with a case of insanity? I studied his physiognomy for some time in silence. He would have been called decidedly handsome; and yet that is not the word. I should rather say beautiful, but the complexion was pallid and the face dreadfully emaciated. The forehead was ample, but half-eclipsed by a mass of rich, chestnut hair that hung over his head in disordered waves. The nose was Grecian; the mouth and chin classic; the eyes were large, dark, and lustrous, with an expression most unusual and indescribable. If I may use the expression, he seemed to look through you and beyond you into space. The expression was quite unlike the vacant stare of the maniac, for the look abounded with superior intelligence, but yet it was not that sort of intelligence which men get by mixing in the world. His look had something _unearthly_ in it--something of another world. I could not altogether bring myself to believe that he was mad. He would certainly have been called so by the world at large, which calls everything madness that does not come within its own narrow circle. His madness was that his faculties were too acute, his nervous system too sensitive. When he looked at me he seemed to read my inmost thoughts and answer them all with his eyes before I had time to open my mouth to give utterance to them. I tried to reason with him, tried to show him that very good health was compatible with the most exalted thoughts, etc. But he always had an answer ready, and that, too, before the words were half out of my mouth. He was a perfect study, and I took immense interest in him. He, in turn, grew more docile and confiding, and after some five or six visits we were the best of friends. I have said that he slept much and was given much to talking in his sleep. It was on my third visit that I had some experience of this. We were in the midst of an animated discussion, when he suddenly went off into a most profound slumber; more suddenly than I had ever before known anyone to fall asleep, and so resembling death that for some time I thought him dead. At length his lips began to move, and for more than an hour he kept up a conversation with someone in his dream, part of which conversation I committed to paper.
