In the next table (No. XII), the mortality from cholera in 1849 is shown side by side with that of 1854, in the various sub-districts to which the supply of the two water companies with which we are particularly interested extends. The mortality of 1854 is down to October 21, and is extracted from a table published in the “Weekly Return of Births and Deaths” of October 28; that of 1849 is from the “Report on Cholera” by Dr. Farr, previously quoted. The sub-districts are arranged in three groups as before, the first group being supplied only by the Southwark and Vauxhall Company, the second group by this Company and the Lambeth, and the third group by the Lambeth Company only. It is necessary to observe, however, that the supply of the Lambeth Company has been extended to Streatham, Norwood, and Sydenham, since 1849, in which year these places were not supplied by any water company. The situation and extent of the various sub-districts are shown, together with the nature of the water supply, in Map 2, which accompanies this work. =TABLE XII.=
