Fig. 98 is a section across the groove, the guiding rod /, and the bar of the window m, to which the groove is bolted ; n is the handle of the guide-bar. The window is cast in two pieces; the larger (Fig. 99,) being 2 ft. 10 in. high, by 2 ft. 1 in. broad, and the smaller (Fig. 100,) being 1 ft. 4 in. high, by 1 ft. broad, exclusive of the lead along the bottom and sides, which forms the rebate, and covers the joint. In casting the smaller window, it is essentially necessary that it be somewhat less in dimensions than the space into which it is to shut, in order that it may always move freely. The air is kept out from the room within, not by the tight fitting of the sides of the small window to the sides of the frame, but by the contact of the edges of the sides of the small window with the beads forming the rebates attached to the inside of the frame; and also by means of the contact of the beads, or rebates, of the small window with the edge of the sides of the large one, or frame into which it shuts. In consequence of the sides never touching, the window moves with the greatest ease, whether expanded by heat in summer, or contracted by cold in winter, and weather-painted and and smooth, or unpainted and Please note that
