fog everywhere. fog up the river fog down the river,
where it rolls defiled among the tiers of shipping, and the
waterside pollutions of a great and dirty) city. fog lying
out on the yards, and hovering in the rigging of great ships;
fog drooping on the gunwales of barges and small boats.
fog in the eyes and throats of ancient greenwich
pensioners, wheezing by the firesides. chance people
on the bridges peeping over the parapets into a nether sky
of fog, with fog all round them, as if they were up in a
balloon and hanging in the misty clouds.
--charles dickens, bleak house
