As for the great Parisian world outside, my experience of it is bounded by the prospect I obtain of the Champs Elysées from my bed-room window. Fashionable Paris spins and prances by me every afternoon, in all its glory; but what interest have healthy princes and counts and blood-horses, and blooming ladies, plunged in abysses of circumambient crinoline, for me, in my sick situation? They all fly by me in one confused phantasmagoria of gay colours and rushing forms, which I look at with lazy eyes. The sights I watch with interest are those only which seem to refer in some degree to my own invalid position. My sick man's involuntary egotism clings as close to me when I look outward at the great highway, as when I look inward at my own little room. Thus, the only objects which I now notice attentively from my window, are, oddly enough, chiefly those which I should have missed altogether, or looked at with indifference if I had occupied my bachelor apartment in the enviable character of a healthy man. For example, out of the various vehicles which pass me by dozens in the morning, and by hundreds in the afternoon, only two succeed in making anything like a lasting impression on my mind. I have only vague ideas of dust, dashing, and magnificence in connection with the rapid carriages late in the day--and of bells and hollow yelping of carters' voices in connection with the deliberate waggons early in the morning. But I have, on the other hand, a very distinct remembrance of one sober brown omnibus, belonging to a Sanitary Asylum, and of a queer little truck which carries baths and hot water to private houses, from a bathing establishment near me. The omnibus, as it passes my window at a solemn jog-trot, is full of patients getting their airing. I can see them dimly, and I fall into curious fancies about their various cases, and wonder what proportion of the afflicted passengers are near the time of emancipation from their sanitary prison on wheels. As for the little truck, with its empty zinc bath and barrel of warm water, I am probably wrong in sympathetically associating it as frequently as I do with cases of illness. It is doubtless often sent for by healthy people, too luxurious in their habits to walk abroad for a bath. But there must be a proportion of cases of illness to which the truck ministers; and when I see it going faster than usual, I assume that it must be wanted by some person in a fit; grow suddenly agitated by the idea; and watch the empty bath and the hot-water barrel with breathless interest, until they rumble away together out of sight. So, again, with regard to the men and women who pass my window by thousands every day; my view of them is just as curiously circumscribed as my view of the vehicles. Out of all the crowd, I now find, on taxing my memory, that I have noticed particularly just three people (a woman and two men), who have chanced to appeal to my invalid curiosity.
