WARMING AND VENTILATING HOUSES.
Excellent fuel is so cheap in Britain, owing to the profusion with which beds of rich coal are scattered among the mineral treasures of this favoured portion of the earth, that a careless expenditure has arisen; which, however, instead of securing the comfort and health that might be expected, has led to plans of warming that often prove destructive to both. In cold countries, where fuel is more scarce, as in the north of continental Europe, and where, to retain and preserve the heat once obtained, the inhabitants use thick walls, double windows, close joinings, and close stoves or fire-places, which have no communication with the apartments, but draw their supply of air from without, that the temperate air of the room may not be wasted,—these means, when sufficient ventilation is added, prove very favourable to health, by giving a uniform and temperate warmth, instead of extremes and fluctuations. But in England, the apartments, with their open chimnies, may be compared to great aerial funnels, constantly pouring out their warm air through a large opening, and constantly requiring to be replenished; and where, from the irregularity of the supply or of the discharge, the temperature is constantly fluctuating.
By the close stove and apartment fuel is saved to a great extent—they also produce a uniformity of temperature; first, as regards the different parts of the room, so that the occupiers may sit anywhere; and secondly, as regards the different times of the day; for the stove once heated in the morning, often suffices to maintain a steady warmth until night; the heat can be carried to any required degree, and ventilation is easily effected as desired. * * *
Consumption is the disease which carries off a fifth or more of the persons born in Britain, owing in part, no doubt, to the changeableness of the climate, but much more to the faulty modes of warming and ventilating the houses. To judge of the influence of temperature in producing this disease, we may consider—that miners who live under ground, and are always, therefore, in the same temperature, are strangers to it; while their brothers and relations, exposed to the vicissitudes of the weather above, fall victims—that butchers and others who live almost constantly in the open air, and are hardened by the exposure, enjoy nearly equal immunity—that consumption is hardly known in Russia, where close stoves and houses
