The hot-water box may be either of cast-iron in one piece, or of riveted plates of iron or copper. It may be 279 280 mentioned, that it would be an improvement to have what may be called a false bottom to the closet, made of iron, or even of wood, to which the grooves might be attached, 281 282 W C-X cLjb and placed about an inch above the top of the boiler, with an opening (of about half an inch in depth, and the whole width of the closet), at the door, for the admission of the air to be heated, and another at the opposite end, about twice the size, for the escape of the hot air into the closet. The effect of this arrangement would be, to carry off more heat from the cover of the boiler, and consequently to make the closet hotter. The principle has been illustrated in Perkins's steam-generater, as described in the Mechanics' Magazine, vol. xvii. This pipe for circulating the water should be of iron ; and it would be an improvement to have the upper one square, or at least flat at top, about nine inches wide, with projecting flanches of grating, as in fig. 282, so that when the ■whole was laid down, painted of the colour of deal board, and completed, it might ap- pear ornamental rather than otherwise. The grating on each side of the pipe, x x, in fig. 282, it is almost needless to observe, is to admit heat from the under pipe. By having the upper surface of the outgoing pipe no higher than the level of the floor of the apartments, no interruption is offered to the opening of the different doors which pass from the dwelling-rooms into the yard or to the wash-house. The low position of the pipes will also heat the air of the rooms more efltctually than if they were higher ; and,
