    the current would be destroyed, and the air find its way into the House, almost imperceptibly, through numerous apertures screened by wire-wove gauze. 15. On so great a scale, an extensive apparatus is requisite ; but when the air is prepared, it may be stowed away for use, like gas in the various manufactories ; and, as the quan- tity for the extreme numbers can be calculated, any smaller portion could be the more easily supplied. 16. If the temperature be fixed at 55°, the air will require to be warmed for about 200 days; if at 60°, for about 250 days per annum. Although the full power of ventilation is necessary only when the House is assembled, the system should be in per- manent action during the whole session. In the present House, unpleasant effluvia are always perceptible. 17. If the new House of Commons be built to contain 1000 persons, there will be required 240,000 cubic feet of air per hour, according to Tredgold, to supply the consumption by breathing, exhalations, and artificial lights. Until the plans and dimensions of the future Houses be finally determined, it would be premature to say what would be the best mode of arranging the details for warming and ventilating them; but, whatever system be adopted, it would be more satisfactory that it should be tested by experiment as nearly as possible, under the conditions in which it would be practically executed. ] 8. The ventilation must be arranged so as to be combined with, or separated from the warming apparatus, whenever desired. It should continually operate, and constantly afford a pure, wholesome atmosphere; pervading the house, and, as it were, breathing into and flowing through it, but with so gentle a current as to be imperceptible to members ; and the inlets and outlets be perfectly under control, and adjusted to the numbers and state of temperature, relative height, and form of the ceiling, &c. Thus, suppose the area of the house to be 5000 feet, and its height to average 30 feet, and that it will contain, inclu- ding strangers, 1000 persons ; and, according to Faraday, 10
