That the dwellings of the workers in the worst portions of the cities, together with the other conditions of life of this class, engender numerous diseases, is attested on all sides. The article already quoted from the _Artisan_ asserts with perfect truth, that lung diseases must be the inevitable consequence of such conditions, and that, indeed, cases of this kind are disproportionately frequent in this class. That the bad air of London, and especially of the working-people's districts, is in the highest degree favourable to the development of consumption, the hectic appearance of great numbers of persons sufficiently indicates. If one roams the streets a little in the early morning, when the multitudes are on their way to their work, one is amazed at the number of persons who look wholly or half-consumptive. Even in Manchester the people have not the same appearance; these pale, lank, narrow-chested, hollow-eyed ghosts, whom one passes at every step, these languid, flabby faces, incapable of the slightest energetic expression, I have seen in such startling numbers only in London, though consumption carries off a horde of victims annually in the factory towns of the North. In competition with consumption stands typhus, to say nothing of scarlet fever, a disease which brings most frightful devastation into the ranks of the working-class. Typhus, that universally diffused affliction, is attributed by the official report on the sanitary condition of the working-class, directly to the bad state of the dwellings in the matters of ventilation, drainage, and cleanliness. This report, compiled, it must not be forgotten, by the leading physicians of England from the testimony of other physicians, asserts that a single ill-ventilated court, a single blind alley without drainage, is enough to engender fever, and usually does engender it, especially if the inhabitants are greatly crowded. This fever has the same character almost everywhere, and develops in nearly every case into specific typhus. It is to be found in the working-people's quarters of all great towns and cities, and in single ill-built, ill-kept streets of smaller places, though it naturally seeks out single victims in better districts also. In London it has now prevailed for a considerable time; its extraordinary violence in the year 1837 gave rise to the report already referred to. According to the annual report of Dr. Southwood Smith on the London Fever Hospital, the number of patients in 1843 was 1,462, or 418 more than in any previous year. In the damp, dirty regions of the north, south, and east districts of London, this disease raged with extraordinary violence. Many of the patients were working-people from the country, who had endured the severest privation while migrating, and, after their arrival, had slept hungry and half-naked in the streets, and so fallen victims to the fever. These people were brought into the hospital in such a state of weakness,
