The old man smiled and answered: "Well, well, that was a strange delusion. My old eyes—thank Heaven for my old eyes! Yes, yes, sir. I saw a pretty face in the window there, with my own eyes; but it seemed to me to be an excellently well-painted oil portrait."

I turned quickly and looked toward the window; there was no one there, and the blind had been pulled down. "Yes," continued the old man, "yes, sir. Now it is too late to make sure of the matter, for just now the servant, who, as I know, lives there alone in the house of the Countess S——, took the picture away from the window after he had dusted it, and let down the blinds."

"Was it, then, surely a picture?" I asked again, in bewilderment.

"You can trust my eyes," replied the old man. "The optical delusion was strengthened by your seeing only the reflection in the mirror. And when I was in your years it was easy enough for my fancy to call up the picture of a beautiful maiden."

"But the hand and arm moved," I exclaimed. "Oh, yes, they moved, indeed they moved," said the old man smiling, as he patted me on the shoulder. Then he arose to go, and bowing politely, closed his remarks with the words, "Beware of mirrors which can lie so vividly. Your obedient servant, sir."

You can imagine how I felt when I saw that he looked upon me as a foolish fantast. I hurried home full of anger and disgust, and promised myself that I would not think of the mysterious house. But I placed the mirror on my dressing-table that I might bind my cravat before it, and thus it happened one day, when I was about to utilize it for this important business, that its glass seemed dull, and that I took it up and breathed on it to rub it bright again. My heart seemed to stand still, every fibre in me trembled in delightful awe. Yes, that is all the name I can find for the feeling that came over me, when, as my breath clouded the little mirror, I saw the beautiful face of my dreams arise and smile at me through blue mists. You laugh at me? You look upon me as an incorrigible dreamer? Think what you will about it—the fair face looked at me from out of the mirror! But as soon as the clouding vanished, the face vanished in the brightened glass.

I will not weary you with a detailed recital of my sensations the next few days. I will only say that I repeated again the experiments with the mirror, sometimes with success, sometimes without. When I had not been able to call up the vision, I would run to the deserted house and stare up at the windows; but I saw no human being anywhere about the building. I lived only in thoughts of my vision; everything else seemed indifferent to me. I neglected my friends and my studies. The tortures in my soul passed over into, or rather mingled with, physical sensations which frightened me, and which at last made me fear for my reason. One day, after an unusually severe attack, I put my little mirror in my pocket and hurried to the home of Dr. K——, who was noted for his treatment of those diseases of the mind out of which physical diseases so often grow. I told him my story; I did not conceal the slightest incident from him, and I implored him to save me from the terrible fate which seemed to threaten me. He listened to me quietly, but I read astonishment in his glance. Then he said: "The danger is not as near as you believe, and I think that I may say that it can be easily prevented. You are undergoing an unusual psychical disturbance, beyond a doubt. But the fact that you understand that some evil principle seems to be trying to influence you, gives you a weapon by which you can combat it. Leave your little mirror here with me, and force yourself to take up with some work which will afford scope for all your mental energy. Do not go to the avenue; work all day, from early to late, then take a long walk, and spend your evenings in the company of your friends. Eat heartily, and drink heavy, nourishing wines. You see I am endeavouring to combat your fixed idea of the face in the window of the deserted house and in the mirror, by diverting your mind to other things, and by strengthening your body. You yourself must help me in this."

I was very reluctant to part with my mirror. The physician, who had already taken it, seemed to notice my hesitation. He breathed upon the glass and holding it up to me, he asked: "Do you see anything?"

"Nothing at all," I answered, for so it was.

"Now breathe on the glass yourself," said the physician, laying the mirror in my hands.
