I last had the honour of presenting myself to the reader's notice in the character of an invalid laid up in lodgings at Paris. Let me now be permitted to reappear as an invalid laid up, for the time being, in a London cab. Let it be imagined that I have got through the journey from Paris, greatly to my own surprise and satisfaction, without breaking down by the way; that I have slept one night at a London hotel for the first time in my life; and that I am now helplessly adrift, looking out for Furnished Apartments as near as may be to my doctor's place of abode. The cab is fusty, the driver is sulky, the morning is foggy. A dry dog-kennel would be a pleasant refuge by comparison with the miserable vehicle in which I am now jolting my way over the cruel London stones. On our road to my doctor's neighbourhood we pass through Smeary Street, a locality well known to the inhabitants of Northern London. I feel that I can go no further. I remember that some friends of mine live not far off, and I recklessly emancipate myself from the torment of the cab, by stopping the driver at the very first house in the windows of which I see a bill with the announcement that Apartments are to Let. The door is opened by a tall muscular woman, with a knobbed face and knotty arms besprinkled with a layer of grate-dust in a state of impalpable powder. She shows me up into a second-floor front bed-room. My first look of scrutiny is naturally directed at the bed. It is of the negative sort, neither dirty nor clean; but, by its side, I see a positive advantage in connection with it, in the shape of a long mahogany shelf, fixed into the wall a few inches above the bed, and extending down its whole length from head to foot. My sick man's involuntary egotism is as predominant an impulse within me at London as at Paris. I think directly of my invalid's knick-knacks: I see that the mahogany shelf will serve to keep them all within my reach when I am in bed; I know that it will be wanted for no other purpose than that to which I design to put it; that it need not be cleared for dinner every day, like a table, or disturbed when the servant cleans the room, like a moveable stand. I satisfy myself that it holds out all these rare advantages to me, in my peculiar situation, and I snap at them on the instant--or, in other words, I take the room immediately.
