“The facts here referred to go far to explain why fatal fever has been more common in Edinburgh than from other circumstances would have been anticipated.” It might admit of dispute, but, on the whole, it appeared to us that both the structural arrangements and the condition of the population in Glasgow was the worst of any we had seen in any part of Great Britain. II.—PUBLIC ARRANGEMENTS EXTERNAL TO THE RESIDENCES BY WHICH THE SANITARY CONDITION OF THE LABOURING POPULATION IS AFFECTED. I now propose to bring under consideration those parts of the various local reports and communications which most prominently set forth special defects that apparently admit of specific remedies. The defects which are the most important, and which come most immediately within practical legislative and administrative control, are those chiefly _external_ to the dwellings of the population, and principally arise from the neglect of drainage. The remedies include the means for drainage simply, _i. e._, the means for the removal of an excess of moisture; and The means for the removal of the noxious refuse of houses, streets, and roads, by sewerage, by supplies of water, and by the service of scavengers and sweepers. _Town Drainage of Streets and Houses._ The sanitary effects obtainable by an efficient town drainage, independently of all other measures, is exhibited in various parts of the country by such particular instances as the following:— _Dr. Baker_, in his report on the sanitary condition of Derby states:— “At the back of the whole row (on the north side of the street) there runs a series of little gardens, each house possessing one, in width equal to the frontage of the house it belongs to, and in length 56 feet. To every five houses there is a pump; and at the bottom of each garden a double privy, answering for two houses, the cesspool shallow, and open to the air; and to this nuisance many have added a pigsty, and dung or rubbish heap. The inhabitants of this street are poor people, chiefly silk-weavers, and what are here called frame-work-knitters or stockingers. “There are on this (the north) side of the street 54 houses, and between October, 1837, and the latter part of March, 1838, the families inhabiting six adjoining houses in the middle of the row were grievously afflicted with typhus fever, whilst those who dwelt in the remaining 48 houses were comparatively healthy. “The following list will give at one view the details of this visitation. “The houses are numbered from the bottom of the hill towards the top.
