§ 78. But to return to collective examples. Mr. Blencarne, on a view of the sanitary condition of the population, and the causes of mortality within his district, expresses a confident opinion that in that district the average amount of mortality might be reduced one-third by efficient sanitary measures. The saving by a reduction of 71 funerals yearly, or one-third of the burials in that district, at the average expense of funerals for the metropolis, would amount to nearly 1020_l._ per annum. If, as appears to be practicable, there were a reduction of one-half of the expenses of the other two-thirds of the average number of funerals, the total saving from this source would be 2040_l._ per annum to the population inhabiting, according to the last census, 1416 houses. Now the annual share of the expense of the chief structural sanitary arrangements, supposing every house in the district to be deficient, would, on the proximate estimate, amount to a sum of 1829_l._, or less than the amount saved by the reduction of the funeral expenditure, giving the health and longevity, and all the moral and social savings, _plus_ the mere pecuniary saving; these remoter savings being in themselves unquestionably far greater than can be represented by the pecuniary items directly economised. § 79. Whosoever will carefully examine what has been done in scattered and fortuitous instances amongst persons of the same class, following the same occupation, living in the same neighbourhoods, and deriving the same amount of incomes, and will from such examinations judge of the inferences as to what may be done by the more systematised application of the like means, will not deem the representation extravagant, that the same duration of life may be given to the labouring classes that is enjoyed by professional persons of the first class; or that it is possible to attain for the whole of a town population such average durations of life as are attained by portions of existing towns; or say, such an average as is attained by the population of the old town of Geneva, that is to say of 45 years, or six years higher than appears to be attained by the whole population of the county of Hereford, which, as we have seen, is 39 years.
