I had not noticed her particularly. At the present moment I do not remember particularly what she was like. So far as I can recollect she was middle-aged, and was quietly yet well dressed. It was not her face nor her dress that attracted my attention and disturbed the current of my thoughts; the effect I speak of was produced by her strange movements and behaviour. She had been sitting listless, probably thinking of nothing at all, or nothing in particular, when, in turning her eyes round, and finding that she could see nothing of the paintings, she began to study me. This did concern me greatly. A cat may look at the king; but to be contemplated by a lady is a compliment sufficient to please any gentleman. It was not gratified vanity that troubled my thoughts, but the consciousness that my appearance produced--first of all a startled surprise, then undisguised alarm, and, finally, indescribable horror. Now a man can sit quietly leaning on the head of his umbrella, and glow internally, warmed and illumined by the consciousness that he is being surveyed with admiration by a lovely woman, even when he is middle-aged and not fashionably dressed; but no man can maintain his composure when he discovers himself to be an object of aversion and terror. What was it? I passed my hand over my chin and upper lip, thinking it not impossible that I might have forgotten to shave that morning, and in my confusion not considering that the fog would prevent the lady from discovering neglect in this particular, had it occurred, which it had not. I am a little careless, perhaps, about shaving when in the country; but when in town, never. The next idea that occurred to me was--a smut. Had a London black, curdled in that dense pea-soup atmosphere, descended on my nose and blackened it? I hastily drew my silk handkerchief from my pocket, moistened it, and passed it over my nose, and then each cheek. I then turned my eyes into the corners and looked at the lady, to see whether by this means I had got rid of what was objectionable in my personal appearance. Then I saw that her eyes, dilated with horror, were riveted, not on my face, but on my leg. My leg! What on earth could that harmless member have in it so terrifying? The morning had been dull; there had been rain in the night, and I admit that on leaving my hotel I had turned up the bottoms of my trousers. That is a proceeding not so uncommon, not so outrageous as to account for the stony stare of this woman's eyes. If that were all I would turn my trousers down. Then I saw her shrink from the chair on which she sat to one further removed from me, but still with her eyes fixed on my leg--about the level of my knee. She had let fall her umbrella, and was grasping the seat of her chair with both hands, as she backed from me.
