The epidemic which began in 1817 continued in London throughout the years 1818 and 1819, chiefly in the densely populated poorer quarters of the town. Two instances of the London slums of the time came to light before the House of Commons Committee on Mendicity and Vagrancy in 1815-16: firstly, Calmel’s Buildings, a small court near Portman Square, consisting of twenty-four houses, in which lived seven hundred Irish in distress and profligacy, neglected by the parish and shunned by everyone from dread of contagion; and, secondly, George Yard, Whitechapel, consisting of forty houses, in which lived two thousand persons in a similar state of wretchedness. The dwellings of the poorer classes in London at this period, before the alleys and courts began to disappear, were described thus generally by Dr Clutterbuck[310]: “The houses the poor occupy are often large, and every room has its family, from the cellar to the garret. Thirty or forty individuals are thus often collected under the same roof; the different apartments must be approached by a common stair, which is rarely washed or cleansed; there are often no windows or openings of any kind backwards; and the _privies_ are not unfrequently within the walls, and emit a loathsome stench that is diffused over the whole house. The houses are generally situated in long and narrow alleys, with lofty buildings on each side; or in a small and confined court, which has but a single opening, and that perhaps a low gateway: such a court is in fact little other than a well. These places are at the same time the receptacles of all kinds of filth, which is only removed by the scavenger at distant and uncertain intervals, and always so imperfectly as to leave the place highly offensive and disgusting.”
