METROPOLITAN MORTALITY.--From a very interesting and carefully compiled statistical table, published in the London _Medical Times and Gazette_, on the births and deaths in the Metropolis during the past year, it appears, that the number of births was, 39,882 males, and 37,984 females, being a total of 77,866, or an excess of males over females of 1,898. The number of deaths during the same period was 28,096 males, and 27,249 females, or a total number of 55,345 deaths, being an excess of deaths of males over females of 847, or an excess of births over deaths of 22,517. The ages at death were from 0 to 15, 25,712; from 15 to 60, 17,999; and from 60 and upwards, 11,362. The proportion of deaths, in 1851, to population in the several districts of London, will be seen by the following:--In the west districts, the population by the last census was 376,427, and the deaths in 1851 were 8,326; giving a proportion of one death to 45.2 inhabitants. In the north district, population 490,396; deaths 10,860; or one death to 45.1 inhabitants. In the central district, population 393,256; deaths 9.474; or one death to 41.1 inhabitants. In the east districts, population 485,522; deaths 11,819; or one death to 41.1 inhabitants. And in the south districts, population 616,635; deaths 14,884; or one death to 41.4 inhabitants. By a comparison of the above with the former year 1850, it will be observed that the births have increased, in 1851, by 2,554, and the deaths by 6,775. In 1850, the excess of births over deaths was 26,738; while in 1851, it was only 22,517, being a decrease of 4,221. The deaths at the age of 0 to 15 have increased over those of 1850 by 4,341; at the age from 15 to 60, by 1,634; and from 60 and upwards, by 780. THE GREAT WASHED!--During 1851, there were 213,485 bathers at the baths and washhouses establishment, situated in St. Martin’s-in-the-Fields, London; the receipts amounted to £3,437 17_s._ 9_d._ There were 50,290 washers: the number of hours’ washing was 103,836; and the receipts under this head were £499 14_s._ 1_d._ So at “the Model,” in Whitechapel, there were during the same period 156,310 bathers, with £2,143 7_s._ 8_d._, receipts. There were 43,462 washers, who washed for 98,824 hours, and paid £513 1_s._ 2_d._ Taking the Metropolis generally, which as yet yields us reports but of five establishments, of which one was opened on the 2nd of September, we find that during the past year, there were 647,242 bathers, who paid in all £9,141 8_s._ 6_d._; and 132,251 washers, who paid £1,498 19_s._ 2_d._ The sum of the combined receipts is £10,640 7_s._ 8_d._ The country returns yield similar results for the periods during which the establishments have been opened to the public.
