The greater fatality of the zymotic diseases generally, and of measles in particular, in the Town sub-district, cannot fail to be noticed; as well as the high mortality from tuberculous and lung diseases, atrophy of children, croup, &c. It is obvious, in fact, that the diseases which depend on a lowered condition of vitality, or on hereditary taint, are more prevalent in the Town sub-district than in Brompton. So are the diseases that may be correctly described as of a more or less preventable character, such, for example, as the lung diseases which are so fatal at the extremes of life, when the influences of neglect and poverty, on the one hand, and of care and comfort on the other, are so strong for evil or for good in the exposure of young and old to, or their preservation from, the predisposing causes of disease. The diseases which mark the later periods of life are, as might be expected, prominently noticeable in the Brompton mortality, such, for instance, as the brain diseases, apoplexy and paralysis, and heart disease. Cancer was equally fatal in both districts. Croup, on the other hand, was most fatal in the “Town,” and Bright’s disease, by comparison, in Brompton. I say nothing on the relative numbers of deaths attributed to “old age,” as the employment of that term generally implies failure of diagnosis rather than death without disease. Under the heads of the various diseases, and in Tables 3 and 3a (Appendix), I have specified in detail the causes of death; but in these introductory general remarks it will not be out of place to refer to the mortality in the parish as a whole from some of the principal classes and orders of diseases. Thus the seven principal diseases of the zymotic class (or rather _six_, for there was no death from small-pox) were accountable for 388 deaths—a mortality equivalent to 2.8 per 1,000 persons living, and to 144 out of every 1,000 deaths. Chest diseases, other than phthisis, killed 554 persons (an increase of 71 over 1873), equivalent to 4 per 1,000 of the population, and to 208 per 1,000 deaths. Tuberculous diseases (including phthisis, scrofula, rickets, and tabes) were the causes of 326 deaths, or 2.3 per 1,000 living, and 121 per 1,000 deaths. Nearly allied to these diseases, if not identical in origin, are the wasting diseases of children, viz., those registered as marasmus, atrophy, debility, want of breast milk, and premature birth. These killed 209 children under five years of age, equal to 1.5 per 1,000 living, and to 77 per 1,000 deaths. The convulsive diseases of infants (hydrocephalus, infantile meningitis, convulsions, and teething) were fatal to 161 infants under five, or 1.1 per 1,000 living, and 59 per 1,000 deaths (_vide_ Table 4, Appendix). Constitutional diseases caused 591 deaths = 4.2 per 1,000 living, and 232 per 1,000 deaths. Local diseases caused 1,143 deaths = 8.3 per 1,000 living, and 434 per 1,000 deaths.
