In these statements of the registrar, the different districts of the Metropolis are placed in a list according to their healthiness, those in which the fewest persons die in a year out of a given equal number, standing first, followed by those next in sanitary order, until we come down to those which are but just above the average for all London. Passing that Rubicon, we see the names of those parishes in which death gets more than his proper proportion of victims every year; and then, one after another, down, down the list, until we reach its lowest depths, in those places where filth and fever reign paramount, and where such a destroyer as Cholera finds hundreds of victims already weakened by previous unhealthy influences, and ready to fall a rapid and easy prey. Let us go through this graduated scale, that shows how health and disease struggle for the mastery, and how death turns the balance. First on the list stands Lewisham, a large parish stretching from Blackheath across the open hilly fields towards Norwood, and including the hamlet of Sydenham. Its rural character, scattered population, and good water, explain its pre-eminence on the sanitary scale. The second name on the list carries us at once from a green suburban parish to one of the centres of fashion and aristocracy,—to St. George, Hanover Square. The presence of this parish, so high up on the scale, is due to several circumstances; and its claims to such prominence are more artificial than those of its rural competitor for the palm of healthfulness. The scale is made out from the census of 1841, which was taken during the height of the London season, when St. George’s was of course much fuller than it is on the general average of the year. Its population, too, is to a great extent composed of servants “in place,” and, therefore, generally young and in good health, and who, when dangerously sick, are sent to the hospitals, or to the country to die. The masters and mistresses of St. George’s, also, are so circumstanced, that when in bad health they can try the sea-air, or retire to country seats. All these facts tend to lessen the mortality of the district, and thus tend to place it high up on the sanitary scale. Its advantages are, an average elevation of forty-nine feet above the high water mark of the Thames; its neighbourhood to the parks; its wide open streets; a supply of water drawn from a Company whose system of filtration is very good; a comparatively thin population, compared with its extent, there being, in this parish, only sixty-six persons to an acre; and the size and character of its houses, which return an average rental of 153_l._ a year.
