    Here the mortality amongst females aged 10-35 is lowest, it is true, in the richer group of districts, but then there is a still more important difference in the mortality amongst males, so that the female deathrate in both groups is lower than that amongst males at ages 20 and upwards, and there is no ground for saying that it is comparatively excessive in the poorer districts. This anomaly, it appears to me, is caused by the existence of mihtary hospitals at Chatham, in which there is a very heavy mortality not properly belonging to the district. If we exclude the Registration Districts of Medway, Maidstone and Gravesend, we have an almost entirely rural population in the residue of the Chelmsford and Maidstone Districts. The Registration Districts of Edmonton, Barnet and Uxbridge being excluded from the other group, it also is freed from the disturbance to its mortality caused by the great lunatic asylums of Hanwell and Colney Hatch, as well as the semi-suburban district extending northwards from Hackney, and becomes likewise in a great measure rural. The mortaHty in the diminished groups is found to be as under :— Ages. DeATHKATES, 1851-60 (BXCLUDINQ ToWNS, &0.). Districts a and e. Districts 5, c and d. Males. Females. Males.

At each age from 10 to 35 the female mortality as shown above is both absolutely and relatively highest in the less wealthy of the two groups. But, it may be urged, exceptional circumstances affect what I have termed the Inner Belt, Let us see what would be the figures for the Outer Belt, after excluding the principal towns, and the military camps at Aldersliot and Shorncliffc.
