In London Labour and the London Poor edition: 

Phase 1

Of the Street Sellers of Live Birds. (Volume 2): "The localities where these men "catch," are the neighbourhoods of the places I have mentioned as their residences, and at Holloway, Hampstead, Highgate, Finchley, Battersea, Blackheath, Putney, Mortlake, Chiswick, Richmond, Hampton, Kingston, Eltham, Carshalton, Streatham, the Tootings, Woodford, Epping, Snaresbrook, Walthamstow, Tottenham, Edmonton—wherever, in fine, are open fields, plains, or commons around the metropolis."

London Considered as a Great World. (The Great World of London): "If then, by some volcanic convulsion - some subterranean quake and explosion - the earth were suddenly to burst, like a mundane bomb, and, being shattered into a score or two of terroid fragments, the great Metropolis were to be severed from the rest of the globe, London is quite large enough to do duty as a separate world, and to fall to revolving by itself about the sun - with Hampstead and Sydenham for its north and south poles, doomed alike to a six months' winter - with the whole line of Oxford Street, Holborn, and Cheapside, scorching under the everlasting summer of what would then be the metropolitan torrid zone, and whilst it was day at Kensington, night reigning at Mile End."
