It was a foggy day in London, and the fog was heavy and dark. Animate London, with smarting eyes and irritated lungs, was blinking, wheezing, and choking; inanimate London was a sooty spectre, divided in purpose between being visible and invisible, and so being wholly neither.

I landed in London on a wintry autumn evening. It was dark and raining, and I saw more fog and mud in a minute than I had seen in a year. I walked from the Custom House to the Monument before I found a coach; and although the very house-fronts, looking on the swollen gutters, were like old friends to me, I could not but admit that they were very dingy friends.

For a week or a fortnight I can write prodigiously in a retired place (as at Broadstairs), and a day in London sets me up again and starts me. But the toil and labour of writing, day after day, without that magic lantern, is IMMENSE!!... My figures seem disposed to stagnate without crowds about them.

This is a London particular . . . A fog, miss.
