The Pointed Arch, if found anywhere in the arches of Decoration, is generally to be seen in the CLERE-STORY, the highest part of the building, and consequently the latest in point of construction. Plain pointed quadripartite VAULTING not unfrequently covers the side-aisles, and sometimes the centre-aisle. The contrast presented by the discriminate use of the two forms of arch before mentioned, is sometimes strikingly exhibited in the side-aisles, where it is by no means uncommon to find a large plain circular window placed immediately under an acutely pointed wall rib, forming part of the contemporaneous pointed VAULTING of the side-aisle.
