“ As we see by the frontispiece, it is not only thickly covered with arcading and statues, but also it is very much enriched with trefoils, quatrefoils, and cinquefoils, especially in the spaces over the doors in the lowest stage, and in the pediment above the great window. The prevalence of the ball-flower decoration should not escape notice; upon the third stage and the spires it constantly occurs, although it is not encountered in the first and second stages, except in the modern tracery of the west window. ”
