    pation. When we compare the phthisis death-rate with other places, we find, from Farr's statistics, that in years 1850-54 there was a mean mortality from phthisis of 2.811, in 1855-57 a mor- tality of 2.683, and in years 1857-63 a mortality of 2.574 ; and in Scotland, from 1858 to 1861, a mortality of 3 per 1000, for Leith 2 per 1000, and for Glasgow 4 per 1000 living. It will at once be seen that these rates exceed very much the death-rates from phthisis in an almost purely mining district. Although we have thus a low mortality from phthisis, of course it might be that the effect of occupation might show itself in increased deaths from other causes. A reference to other tables will show that for the same periods as already given, the mortality from all causes given in the' mean was 15.79 per 1000 living, and this, of course, is a tolerably low mortality. Comparing this rate with the rate for all England for twelve periods, we find that the rate of the latter exceeds this by about 4 deaths per 1000. Coming to the last column, we have the mean age at death of miners, and the average for twelve years we find is 43.1. In the list of deaths I found that one miner died at the age of 86, one at 74, another at 73, and several at 69 ; and those men were miners when the con- ditions of occupation were much more unfavourable than those experienced at the present day.
