The years 1792 and 1793 passed, says Ferriar, without any extraordinary increase of fever patients, although the noxious influences were always present. But in the summer and autumn of 1794 “the usual epidemic fever” became very prevalent among the poor in some quarters of the town, particularly after a bilious colic had raged among all ranks of people. This was a time when work was slack; many workmen enlisted and left their families. In November and December 1794, as many as 156 sent applications to the Infirmary in a week to be visited in fever at their homes. This was a memorable time of scarcity and distress all over the country, the beginning of a twenty-years’ period of so-called “war-prices,” when farmers’ profits were so large that they could afford to double or treble their rents to the landlords. The history of epidemics comes at this point into close contact with the economic history, which I shall touch on in the sequel, after giving a few more particulars of typhus in England and Scotland generally, previous to the outbreak of the war with France in 1793. Typhus in England and Scotland generally, in the end of the 18th century. The introduction of machinery and the building of mills brought typhus fever to places much less crowded than Leeds, or Manchester, or Carlisle. Dr David Campbell of Lancaster saw much of typhus in that town, and in mill villages near it, in the years 1782, 1783, and 1784. In Lancaster town he saw about 500 cases, of which 168 were in men, with 20 deaths, 236 in women, with 11 deaths, and 94 in children under fourteen, with 3 deaths. At Backbarrow cotton mill, twenty miles from Lancaster, there were 180 cases, of which 38 were in men, with 5 deaths, 11 in women, with 2 deaths, and 131 in children under fourteen, with no deaths[269]. At this mill there was an extremely offensive smell in the rooms, which came from the privy; the doors of the latter, “for indispensable reasons in the economy of these works, where so many children are employed, always communicate with the workrooms.” Every care had been taken to keep the air sweet, but without effect. The offensive smell was in all the cotton mills from the same cause; and in the Radcliffe mill belonging to Mr Peel, the typhus was ascribed to that source, the nuisance having been at length got rid of. Both at Backbarrow and Radcliffe the houses of the workpeople were new, airy and comfortable. In the same years typhus raged with uncommon severity at Ulverston and in various parts of Lancashire, where cotton-mills had been set up[270].
