ning the clerestory windows, has greatly added to the effect of
the wall of glass at the east end. There are also slight points of
difference in the clerestory windows, showing the transitional character
of those in the four eastern bays. The windows of the aisle are
delicately moulded with capitals to their shafts, and are ornamented
with a crocketed gable, ogee-shaped and topped with a prominent finial
rising just above the battlements of the aisle. These battlements are
pierced with cusped circles, below them is a cornice ornamented with
foliage. The buttresses of the aisles are decorated with gargoyles and
crowned with pinnacles of a considerable size with crocketed spires and
finials. The front of these pinnacles is ornamented with characteristic
Perpendicular panelling. The buttresses of the main wall are thin and
plain, and, with the pinnacles, much resemble those of the nave. The
battlements are of pierced stonework of a common Perpendicular pattern.
The eastern transepts do not project beyond the aisles. Their fronts
contain very long windows of five lights, each with three transoms. The
southern one has strong buttresses ornamented with panelling, and
gargoyles at the corners. The northern is much plainer. Their side
windows are like those of the clerestory. Britton conjectures that the
unfinished state of the stonework on the north side of the choir beneath
the window shows that a cloister or other low building was intended in
this part, which was never executed. The cornice, he says, under the
battlements is more perfect towards the western part and shows beautiful
foliage. The spouts are sculptured with bold projecting figures through
which the water is conveyed from the roofs.

The east end of the cathedral is square. The great east window of nine
lights fills almost the whole of the central division. The buttresses
separating it from the aisle are decorated with six storeys of niches,
two to each storey, except the lowest, which contains only one. The east
window has an ogee gable above it, topped by a curious pierced pinnacle
at present in process of restoration. The ends, both of the aisles and
of the choir itself, are square, and do not reveal the roof behind them.
The arch of the great east window is surrounded with panelling, each
panel curiously broken at different heights by cusped arches. The aisle
windows have ogee gables above them with finials, and immed
