With a view to have the most perfect security against cold blasts and fluctuation of temperature in rooms intended for invalids, and still to retain the so much valued appearance of the open fire, a glazed frame or window may be placed at the entrance of the chimney, so as completely to prevent the passage of air from the room to the fire. The close room will then be warmed by the fire through the glass, as a green-house is warmed by the rays of the sun. It is true, that the heat of combustion does not pass through glass so readily as the heat of the sun; but the difference is not important. The glass of such a window must, of course, be divided into small panes, and supported by a metallic frame work; and there must be a flap or door in the frame work, for the purpose of admitting the fuel and stirring the fire. Air must be supplied to the fire as described above, by a tube leading directly from the external atmosphere. The ventilation of the room may be effected by an opening into the chimney near the ceiling; and the temperature may be regulated with great precision by a valve placed in this opening, and made to obey the dilatation and contraction of a piece of wire affixed to it, the exact length of which at any time will depend on the temperature of the room. The author first imagined such an arrangement of rooms for the winter residence of a person who was threatened with consumption; and the happy issue of the case, and of others treated on similar principles, has led him to doubt, whether many of the patients with incipient consumption, who are usually sent to warmer climates, and who die there after hardships on the journey, and mental distress from the banishment sufficient to shake even strong health, might not be saved, by judicious treatment in properly warmed and ventilated apartments, under their own roofs, and in the midst of affectionate kindred. _Arnott's Elements of Physics._ * * * * * LORD ORFORD'S DESCRIPTION OF THE DEATH OF GENERAL WOLFE.
