    F. On the occasional and decided predominance ot female over male mortality from Phthisis. Sixth Report of the Medical Officer of the Privy Council, 1864. pp. 23, 24. When many persons are employed together in any in-door industry, the ventilation of the workplace is Hkely to be so bad as to convert the employment, which perhaps in its own nature is not of hurtful tendency, into an employment seriously dan- gerous to health. Here (as I anticipated in my report of 1858) lies the explanation of a fact most deplorable for the working classes of our country,—that, iii proportion as the people of a district are attracted to any collective in-door occupation, in such proportion, other things being equal, the district death-rate by lung-diseases will be increased. For the bad ventilation which, as a rule, belongs to the place of employment, tends to develope among the workpeople a large excess of Phthisis, and probably also some excess of other fatal Lung-disease. And probably in all England there is no exception to the rule, that, in every district which has a large in-door industry, the increased mortality of the workpeople is such as to colour the death-return of the whole district with a marked excess of Lung-Disease. The mortuary statistics, recently laid before Parhament, place this matter in a singularly striking light. In those returns, for instance, it may be seen, that while about one hundred deaths by Phthisis and other Lung-Diseases are occurring in various agricultural districts of England among men aged from 15 to jj, there occur, on similar masses of population, in Coventry one hundred and sixty-three such deaths, in Blackburn and Skipton one hundred and sixty- seven, in Congleton and Bradford one hundred and sixty- eight, in Leicester one hundred and seventy-one, in Leek one hundred and eighty-two, in Macclesfield one hundred and eighty-four, in Bolton one hundred and ninety, in Nottingham one hundred and ninety-two, in Rochdale one hundred and ninety-three, in Derby one hundred and ninety-eight, in Salford and Ashton-under-Lyme two hundred and three, in
