The PINNACLES have often the same ornament, and are crowned with finials composed of a bunch of foliage. The CORNICE often carries a large ornamental leaf in its hollow, and the projecting Corbel-table is no longer seen. The earlier WINDOWS exhibit tracery which consists almost exclusively of plain foliated circles; but in the later examples other simple geometrical forms were employed. The heads of the window lights, occasionally plain, were more frequently, even in the earlier examples, and invariably in the later ones, cusped or foliated. The CLERE-STORY usually contains a single window, or at most a pair, containing tracery similar to that of the side-aisle windows, and the Clere-story arcade altogether disappears. The CORNICE is usually similar to that of the side-aisles. _Interior Compartment._ The PIERS have occasionally, in the earlier examples, detached shafts; but they more usually consist of a solid mass of engaged shafts, separated by hollow mouldings, and disposed on the plan of a spherical triangle. The BASES consist generally of a triple roll, standing on the usual plinth; and the CAPITALS carry foliage disposed much more freely and gracefully than in the preceding Period, and frequently of exquisite design. The PIER-ARCHES have usually mouldings in three orders of very elegant profile, not so deeply cut, however, as in the Lancet Period: the favourite dog-tooth is nowhere seen, but late in the period a substitute for it was found in the ornament called the _Ball-flower_. All BOSSES, FIGURES, and SCULPTURES of every kind are carved in the very best manner; and all STRING-COURSES and HOOD-MOULDINGS are moulded with the greatest care and elegance; indeed the art of carving in stone may be said to have attained its greatest perfection during this Period. The TRIFORIUM in the earlier examples commonly contains a pair of double arches, carrying circular tracery in their heads: in the later examples, it becomes greatly reduced in size and prominence, and is made entirely subordinate to the Clere-story; and consists often of a low foliated arcade, or a band of plain tracery. The inner arcade of the CLERE-STORY altogether disappears, and in its place is sometimes found a plane of Geometrical Tracery, corresponding with that of the window; but more commonly a single arch spans the entire compartment; and sometimes the gallery is dispensed with altogether. The AISLE-ARCADE is often very elegant; the arches are usually foliated, and covered with a straight-sided canopy. Occasionally this arcade consists of a series of beautiful panels containing geometrical tracery, with mouldings of a very minute and elegant character. Both the centre and side-aisles are generally covered with VAULTING of simple form, having characteristic bosses and rib-mouldings. PRINCIPAL BUILDINGS OF THE GEOMETRICAL PERIOD.
