MY DEAR FRIEND: Old associations cling to the mind with astonishing tenacity. Daily custom grows up about us like a stone wall, and consolidates itself into almost as material an entity as mankind’s strongest architecture. It is sometimes a serious question with me whether ideas be not really visible and tangible, and endowed with all the other qualities of matter. Sitting as I do at this moment in my hired apartment, writing beside the hearth, over which hangs a print of Queen Victoria, listening to the muffled roar of the world’s metropolis, and with a window at but five paces distant, through which, whenever I please, I can gaze out on actual London,—with all this positive certainty as to my whereabouts, what kind of notion, do you think, is just now perplexing my brain? Why,—would you believe it?—that all this time I am still an inhabitant of that wearisome little chamber,—that whitewashed little chamber,—that little chamber with its one small window, across which, from some inscrutable reason of taste or convenience, my landlord had placed a row of iron bars,—that same little chamber, in short, whither your kindness has so often brought you to visit me! Will no length of time or breadth of space enfranchise me from that unlovely abode? I travel; but it seems to be like the snail, with my house upon my head. Ah, well! I am verging, I suppose, on that period of life when present scenes and events make but feeble impressions in comparison with those of yore; so that I must reconcile myself to be more and more the prisoner of Memory, who merely lets me hop about a little with her chain around my leg.
