Laughing pleasantly over this incident, he said, soon afterward,--“A very singular occurrence took place the day I was nominated at Chicago, four years ago, of which I am reminded to-night. In the afternoon of the day, returning home from down town, I went up-stairs to Mrs. Lincoln’s sitting-room. Feeling somewhat tired, I lay down upon a couch in the room, directly opposite a bureau upon which was a looking-glass. As I reclined, my eye fell upon the glass, and I saw distinctly _two_ images of myself, exactly alike, except that one was a little paler than the other. I arose, and lay down again, with the same result. It made me quite uncomfortable for a few moments, but some friends coming in, the matter passed out of my mind. The next day, while walking in the street, I was suddenly reminded of the circumstance, and the disagreeable sensation produced by it returned. I had never seen anything of the kind before, and did not know what to make of it. I determined to go home and place myself in the same position, and if the same effect was produced, I would make up my mind that it was the natural result of some principle of refraction or optics which I did not understand, and dismiss it. I tried the experiment, with a like result; and, as I had said to myself, accounting for it on some principle unknown to me, it ceased to trouble me. But,” said he, “some time ago, I tried to produce the same effect _here_, by arranging a glass and couch in the same position, without success.” He did not say, at this time, that either he or Mrs. Lincoln attached any omen to the phenomenon; neither did he say that the double reflection was seen while he was walking about the room. On the contrary, it was only visible in a certain position and at a certain angle; and therefore, he thought, could be accounted for upon scientific principles.[7]
