I need hardly say that I was greatly disturbed in mind and feelings, and forgot all about the origin of the English schools of painters, and the question why the British Museum is more popular than the National Gallery. Thinking that I might have been spattered by a hansom whilst crossing Oxford Street, I passed my hand down my side hastily, with a sense of annoyance, and all at once touched something cold, clammy, that sent a thrill to my heart, and made me start and take a step forward. At the same moment, the lady, with a cry of horror, sprang to her feet, and with raised hands fled from the room, leaving her umbrella where it had fallen. There were other visitors to the Picture Gallery besides ourselves, who had been passing through the saloon, and they turned at her cry, and looked in surprise after her. The policeman stationed in the room came to me and asked what had happened. I was in such agitation that I hardly knew what to answer. I told him that I could explain what had occurred little better than himself. I had noticed that the lady had worn an odd expression, and had behaved in most extraordinary fashion, and that he had best take charge of her umbrella, and wait for her return to claim it. This questioning by the official was vexing, as it prevented me from at once and on the spot investigating the cause of her alarm and mine--hers at something she must have seen on my leg, and mine at something I had distinctly felt creeping up my leg. The numbing and sickening effect on me of the touch of the object I had not seen was not to be shaken off at once. Indeed, I felt as though my hand were contaminated, and that I could have no rest till I had thoroughly washed the hand, and, if possible, washed away the feeling that had been produced. I looked on the floor, I examined my leg, but saw nothing. As I wore my overcoat, it was probable that in rising from my seat the skirt had fallen over my trousers and hidden the thing, whatever it was. I therefore hastily removed my overcoat and shook it, then I looked at my trousers. There was nothing whatever on my leg, and nothing fell from my overcoat when shaken.
