The London Fog

Just wanted to note that apparently there was a constant fog lingering over London in the winters of the Regency Era, a result of fossil coals as fuel.

Mr. Simond’s, an American in Regency London, writes, March 5 1810:

“The inhabitants of London, such as they are seen in the streets, have, as well as the outside of their houses a sort of dingy, smoky look; not dirty absolutely–for you generally perceive clean linen–but the outside garments are of a dull, dark cast, and harmonize with mud and smoke. Prepossessed with a high opinion of English corpulency.”
