In London Labour and the London Poor edition: 

Phase 1

A Visit to the Rookery of St. Giles and its Neighbourhood. (Volume 4): "Leaving the Seven Dials and its dingy neighbourhood, we went to Oxford Street, one of the first commercial streets in London, and one of the finest in the world. It reminded us a good deal of the celebrated Broadway, New York, although the buildings of the latter are in some places more costly and splendid, and some of the shops more magnificent."

London Considered as a Great World. (The Great World of London): "In short, London may be safely asserted to be the most densely-populated city in all the world - containing one-fourth more people than Pekin, and two-thirds more than Paris; more than twice as many as Constantinople; four times as many as St. Petersburg; five times as many as Vienna, or New York, or Madrid; nearly seven times as many as Berlin eight times as many as Amsterdam; nine times as many as Rome ; fifteen times as many as Copenhagen; and seventeen times as many as Stockholm."

Phase 2

Irish Lodging-houses for Immigrants. (Volume 1)
