The wit of the Counting-House became in a moment as mute as the row of leathern fire-buckets hanging up behind him. Such vapid and flat daylight as filtered through the ground-glass windows and skylights, leaving a black sediment upon the panes, showed the books and papers, and the figures bending over them, enveloped in a studious gloom, and as much abstracted in appearance, from the world without, as if they were assembled at the bottom of the sea; while a mouldy little strong room in the obscure perspective, where a shaded lamp was always burning, might have represented the cavern of some ocean monster, looking on with a red eye at these mysteries of the deep. ~ Dombey and Son
