Districts. Annual Deaths. 1 in Hackney 57·87 St. George, Hanover Square 57·05 Camberwell 55·34 Islington 50·03 Rotherhithe 38·58 Clerkenwell 38·54 St. Luke 38·49 Greenwich 38·42 St. George, Southwark 33·77 East and West London 33·50 St. Giles and St. George 33·46 Whitechapel 28·15 Yet it is to be observed that the best and the worst districts present striking instances of extremes of condition in the residences and the inhabitants. In the Bethnal Green and the Whitechapel unions, in which are found some of the worst conditioned masses of population in the metropolis, we also find good mansions, well drained and protected, inhabited by persons in the most favourable circumstances. Immediately behind rows of the best-constructed houses in the fashionable districts of London are some of the worst dwellings, into which the working classes are crowded; and these dwellings, by the noxious influences described, are the foci of disease. These returns are all from large parishes, containing the mean results from all classes. If it had been practicable to give correctly the average rate of mortality prevalent in different classes of streets, the variation of results, it is to be presumed, from the variations of circumstances, would have been much greater. Since the character of the residences of many of the labouring classes, and the condition of their places of work and their habits are known, it is to be considered that where the occupations are duly registered, returns, on the principle of those we have first given of the average age of death amongst particular classes will afford the most close approximation to accuracy, or the best indications of the extent of the operation of the noxious circumstances under which each of those classes is placed.[19] A LINEAR REPRESENTATION _of the number of Deaths in the Metropolis, from Epidemic, Endemic and Contagious disease; Diseases of the Brain, Nerves & Senses; diseases of Respiratory Organs and diseases of the Heart & Blood Vessels: also the number of Deaths from Small Pox, Scarlet Fever, Measles; Typhus Fever, Hooping Cough, and, all other Epidemic diseases, during each Four Weeks of the Two Years, ended the 1st January, 1842._ (_Population of 1841.—1,870,727._) [Illustration: _Sanitary Report P.L.C._ ]
