A neat design of holes is punched out of the solid plate, leaving the material intact, where it acts in a similar manner to diagonals. As holes show much better than mere lines or raised ornaments, the effect is much more powerful ; besides, it seems the only right way to ornament a plate girder, because the main construction lines, adapted to certain scientific laws, are not only left intact, but even brought...
Page 46 - At a height of 19 ft. 7 in. from floor level it widens out into an octagon capital of 2 ft 9 in. inscribed diameter at the top. The base is plain. The top is a little ornamented by raised leaves. Above that, the column widens out into a kind of flat box, 4 ft. 2 in. high, with a bracket in front, supporting the horizontal plate to which the L irons of base of columns are bolted. The horizontal plate extends over the middle of the continued column, leaving on each side of bracket openings for receiving...
Page 228 - Atlantic, found that in the torrid zone the quantity of vapour contained in the air, is much nearer to the point of saturation than in the temperate zone. The evaporation within the tropics is, on this account, less than might have been supposed from the increase of the temperature.
