It is clear from other tables given by Holland that the mortality in the _streets_ of the second class is 18 per cent. greater, and in the streets of the third class 68 per cent. greater than in those of the first class; that the mortality in the _houses_ of the second class is 31 per cent greater, and in the third class 78 per cent. greater than in those of the first class; that the mortality is those bad streets which were improved, decreased 25 per cent. He closes with the remark, very frank for an English bourgeois: {107} "When we find the rate of mortality four times as high in some streets as in others, and twice as high in whole classes of streets as in other classes, and further find that it is all but invariably high in those streets which are in bad condition, and almost invariably low in those whose condition is good, we cannot resist the conclusion that multitudes of our fellow-creatures, _hundreds of our immediate neighbours_, are annually destroyed for want of the most evident precautions." The Report on the Sanitary Condition of the Working-Class contains information which attests the same fact. In Liverpool, in 1840, the average longevity of the upper-classes, gentry, professional men, etc., was thirty-five years; that of the business men and better-placed handicraftsmen, twenty-two years; and that of the operatives, day-labourers, and serviceable class in general, but fifteen years. The Parliamentary reports contain a mass of similar facts.
