Liverpool, in the last quarter of the 18th century, came next in size to London, having a population (in 1790) of 56,000 to the capital’s estimated 800,000. According to a medical author, whose experiences lay among the middle classes, it was everything that could be wished in the way of healthfulness and prosperity; but it had a dark side as well. About 7,000 of the people lived in cellars underground, and nearly 9,000 in back houses, in small confined courts with a narrow passage to the street. “Among the inhabitants of the cellars,” says Currie[250], “and of these back houses, the typhus is constantly present; and the number of persons under this disease that apply for medical assistance to the charitable institutions, the public will be astonished to hear, exceeds three thousand annually.... In sixteen years’ practice I have found the contagious fever of Liverpool remarkably uniform among the poor. Seldom extending itself in any considerable degree among the other classes of the community, it has been supposed that Liverpool was little subject to fever; but this will be shewn from authentic documents to be a great and pernicious error.” At the Dispensary in the year 1780 the cases of typhus averaged 160 per month, the numbers being as remarkably steady from month to month as from year to year. In the ten years from 1 January, 1787, to 31 December, 1796, 31,243 cases of fever were entered on the books of the Dispensary, an average of 3124 per annum[251]. Of 213,305 cases of all diseases at the Dispensary in seventeen years, 1780 to 1796, 48,367, nearly one-fourth, were labouring under typhus. Supposing that these were all the cases of typhus in Liverpool, and that 1 in 15 died, we should have some 150 deaths from typhus in a year. Supposing also that typhus was relatively as common at that time in London, it will follow that nearly all the deaths under “fever” in the bills of mortality might well have been from typhus fever; for London in its several densely populated out-parishes was the fever-quarter of Liverpool a dozen times over[252].
