I was about to reply that I was more than willing to do so when the door opened and a person entered--evidently the mistress of the house. She was tall and thin, past middle age, and plainly dressed. Her pale countenance wore a defiant look, and behind her spectacles blazed a pair of dark eyes, which, after an instant's survey of her visitors, were fixed steadily upon me. She made but a step into the room, and stood holding the door. We both rose from our chairs. "You can sit down again," she said sharply to me. "I don't want you. Now, sir," she continued, turning to Uncle Beamish, "please come with me." Uncle Beamish gave a glance of surprise at me, but he immediately followed the old lady out of the room, and the door was closed behind them. For ten minutes, at least, I sat quietly waiting to see what would happen next--very much surprised at the remark that had been made to me, and wondering at Uncle Beamish's protracted absence. Suddenly he entered the room and closed the door. "Here's a go!" said he, slapping his leg, but very gently. "We're mistook the worst kind. We're mistook for doctors." "That is only half a mistake," said I. "What is the matter, and what can I do?" "Nothin'," said he, quickly,--"that is, nothin' your own self. Just the minute she got me outside that door she began pitchin' into you. `I suppose that's young Dr. Glover,' said she. I told her it was, and then she went on to say, givin' me no chance to explain nothin', that she didn't want to have anything to do with you; that she thought it was a shame to turn people's houses into paupers' hospitals for the purpose of teachin' medical students; that she had heard of you, and what she had heard she hadn't liked. All this time she kept goin' upstairs, and I follerin' her, and the fust thing I knowed she opened a door and went into a room, and I went in after her, and there, in a bed, was a patient of some kind. I was took back dreadful, for the state of the case came to me like a flash. Your uncle had been sent for, and I was mistook for him. Now, what to say was a puzzle to me, and I began to think pretty fast. It was an awkward business to have to explain things to that sharp-set old woman. The fact is, I didn't know how to begin, and was a good deal afraid, besides, but she didn't give me no time for considerin'. `I think it's her brain,' said she, `but perhaps you'll know better. Catherine, uncover your head!' And with that the patient turned over a little and uncovered her head, which she had had the sheet over. It was a young woman, and she gave me a good look, but she didn't say nothin'. Now I WAS in a state of mind."
