The rate of mortality in the Metropolis sensibly increased last week; exceeding the calculated average by 37; but the deaths from cholera de- creased from 98 to 72. The Registrar-General has published a supplementary report on the state of the water-supply of London and its relation to the movements of the cholera. He shows, that the deaths from cholera in 1849 were pretty nearly in proportion to the impurity of the water-supply.

" The mortality from cholera was lowest in districts which have their water chiefly from the Thames so high as Hammersmith and Kew. The mortality was greatest in districts which derive their water from the Thames ■ so low as Battersea and Hungerford Bridge. The districts of the New River occupy an intermediate station. In six districts supplied from Kew and gammersmith, 15 in 10,000 inhabitants died, and the mortality ranged from g to 33. In twenty districts supplied from the Amwell, the Lea, the Ravens- bourne, 48 in 10,000 inhabitants died of cholera, and the mortality ranged from 19 to 96. In the twelve districts supplied from the most impure part of the river, between Battersea and Waterloo Bridge, 123 in 10,000 died, and the mortality ranged from 28 to 205. Elevation or depression of site co- operated with the quality of water to produce these relative results mortality of the third group of districts was three times as great as in the second, though the density of population in the third (73 persons to an acre) was little more than half of what it was in the second."

With one or two exceptions, the water-supply and its sources remain the same as in 1849.

We have had few authentic reports of the progress of the cholera in the Provinces this week. The General Board of Health has, however, furnished a table showing the total of deaths in what may be called the new cholera districts, including Scotland. Since the first outbreak, the number of fatal cases in Dundee has been 139, in Leith 2, in Arbroath 13, in Dalmeny 2 ; in Cockermouth 9, in Durham 3, in Bridport 1, in South Shields 77, in Tunbridge 2. These numbers died between the 6th and 22d November; we have had no other returns.
