London was without cholera from the latter part of 1849 to August 1853. During this interval an important change had taken place in the water supply of several of the south districts of London. The Lambeth Company removed their water works, in 1852, from opposite Hungerford Market to Thames Ditton; thus obtaining a supply of water quite free from the sewage of London. The districts supplied by the Lambeth Company are, however, also supplied, to a certain extent, by the Southwark and Vauxhall Company, the pipes of both companies going down every street, in the places where the supply is mixed, as was previously stated. In consequence of this intermixing of the water supply, the effect of the alteration made by the Lambeth Company on the progress of cholera was not so evident, to a cursory observer, as it would otherwise have been. It attracted the attention, however, of the Registrar-General, who published a table in the “Weekly Return of Births and Deaths” for 26th November 1853, of which the following is an abstract, containing as much as applies to the south districts of London. =TABLE IV.= ┌─────────────┬─────────────────────┬───────────────────────────┬────────────┐ │ Water │ Sources of Supply. │ Aggregate of Districts │ Deaths in │ │ Companies. │ │ supplied chiefly by the │ 100,000 │ │ │ │ respective Companies. │inhabitants.│ ├─────────────┼─────────────────────┼────────────┬──────────────┼────────────┤ │ „ │ „ │ │ Deaths by │ │ │ │ │ │Cholera in 13 │ │ │ │ │ │ wks. ending │ │ │ │ │Population. │ Nov. 19. │ „ │ ├─────────────┼─────────────────────┼────────────┼──────────────┼────────────┤ │(1) Lambeth │Thames, at Thames │ │ │ │ │ and (2) │ Ditton and at │ │ │ │ │ Southwark │ Battersea │ │ │ │ │ and │ │ │ │ │ │ Vauxhall │ │ 346,363│ 211│ 61│ │ │ │ │ │ │ │Southwark and│Thames, at Battersea │ │ │ │ │ Vauxhall │ │ 118,267│ 111│ 94│ │ │ │ │ │ │ │(1) Southwark│Thames, at Battersea;│ │ │ │ │ and │ the Ravensbourne, │ │ │ │ │ Vauxhall, │ in Kent, & ditches │ │ │ │ │ (2) Kent │ and wells │ 17,805│ 19│ 107│
