When the house is to be heated, it is only necessary to light the fire in the stove d, and open one of the cold-air drains b c, as in the present in- stance the internal one b is open; the arrows represent the cold air flowing to- wards the stove where it enters below; and after traversing a numerous forma- tion of winding channels in a heated state, it discharges itself into the brick casing g g, above the flue-pipe, from Fig. which it escapes as heretofore mentioned. When the cold air is taken from the ex- ternal drain c, the internal one b is closed—a regulation, however, which is entirely at the discretion of the superin- tendent of the house. I is the regulator in the ash-pit of stove, the handle of which is turned so as to admit a greater or less quantity of air, by which the com- bustion of fuel in the stove is regulated ; m and n are ventilating grates ; o o rods of iron suspended to the frames of the top windows to open and shut them; p p a system of small roans for conveying the drip from the inside of the roof to the cistern h. The appearance of the front is light and elegant : the main rafters are formed of malleable iron, and the in- tervening sashes of zinc, with an opaque edge, so extremely small as to give the house, at a short distance, th
