That was what struck him afresh after he had mounted the large old stair and begun to pass from room to room: there was something in his impression so indefinably prepared by other hands that acknowledgment surely ought somehow and somewhere to be made. It all came back of course soon enough to thanking Mr. Pendrel, and this in truth Ralph sufficiently did by his mere attitude from point to point. That was the question on the whole as to which he was easiest; wherever he paused to draw a long breath and again look round he felt his gratitude carry and his appreciation in a singular degree picked up and noted. Not yet for that matter had it so affected him this evening as returning richly upon himself. The cold rain was on his window-pane, and it damped the great London hum. These squares of old glass were small and many and the frames that enclosed them thick; the appropriate recess, of which no window failed, was deep, and Ralph could as he looked out rest a knee on the flat cushion, all flowered and faded, that covered the solid bench. He looked out only to look in again under the charm of isolation and enclosure, of being separated from the splashed Square and its blurred and distant life much more by time than by space; under the charm above all of the queer incomparable London light--unless one frankly loved it rather as London shade--which he had repeatedly noted as so strange as to be at its finest sinister, and which just now scattered as never before its air over what surrounded him. However else this air might have been described it was signally not the light of freshness and suggested as little as possible the element in which the first children of nature might have begun to take notice. Ages, generations, inventions, corruptions had produced it, and it seemed, wherever it rested, to have filtered through the bed of history. It made the objects about show for the time as in something "turned on"--something highly successful that he might have seen at the theatre. What was one to call the confounding impression but that of some stamp, some deposit again laid bare, of a conscious past, recognising no less than recognised?
