    The Population in Table F was shewn to be bisected at ages 68-9, while among the Labourers that will be seen to take place at ages 71-2. The sum of the series of differences of the points of equal specific intensity between the Eural, Town, and City Districts respectively, and Table C, were shewn to be 55, 23, and 5 ; but the sum of the same order of differences for Table I is 78; so that the difference between Labourers and the General Eesults for the Eural Districts is more than equivalent to the mean difference between Towns and Cities and the Eural Districts. It will also be seen that the sum of the series of differences of the points of equal specific intensity in the Eural Districts generally, and the Labourers, is 46, being above the mean of 55 and 23. The difference for the equation of life to Age 10, between Eural and Town Districts, is 4 years. „ „ Town- and City „ 3 „ and „ Labourers and Eural „ 3 „ So that, in this general way of viewing the question, employment produces as wide a dis- tinction as locality. If Table J is now referred to, it will be seen that the Expectation of Life among Labourers in the Eural Districts exceeds the Expectation of the Eural Districts generally throughout the whole term of life. At decennial ages the following is the relative value of life. Age. Rural ] General Results. G. Jistricts. Labourers. J. Difference in Favour of Labourers. Age. In Years.
