t that in the
eastern aisle of the south transept the parapet rests on plain corbels,
and above the western clerestory of the other transept is a cornice with
Perpendicular bosses. In this clerestory, again, the buttresses are
Perpendicular, whereas otherwise throughout the transepts they are flat
Norman. Over the eastern aisle of the north there is no cornice or
corbel; "the parapet," says Woodward, "with no more than a water-table
under it, is carried across the gable of the north transept, so as to
form an _alura_ above the buttress, in front of the circular window
there." The Perpendicular rose-window in the northern gable cannot now
be seen from the interior, being hidden by the transept ceiling, but in
the illustration from _Britton_, on page 59, it is visible. The
corresponding gable on the south shows panelling with interlacing Norman
arches, but there are only two narrow lights. Many symptoms show that
square towers were to have been erected flanking the transept gables.
There is an unfinished turret at the north-east corner of the north
transept, while the springing of an arcade and the generally incomplete
appearance prove that a side tower was intended. The other three extreme
angles of the transepts also bear out this view. The width from east to
west of the transepts is enormous as compared with the height of the
central tower above. It rather looks from the presence (barely
perceptible from outside) of the westernmost windows of the presbytery
aisles as if those who carried on Wykeham's work had meant to reduce
this great width, and give more importance to the presbytery and
retro-choir externally. It is certain, at any rate, that the Norman
transepts narrowly escaped a complete transformation. That on the north
side of the cathedral shows very considerable alterations, in the
majority of its windows, from the old Norman pattern. A built-up doorway
may be noticed under the first window from the west of this transept.

The exterior of the #Presbytery# has only three compartments on each
side, but in each there are four lights in aisle and clerestory alike.
The windows are of the Wykeham pattern, though probably a little later
in date than his work. The buttresses, which rise above the aisle roof,
culminate in square panelled pinnacles, surmounted by crocketted ogee
canopies. From these buttresses spring graceful flying-buttresses, with
pierced spandrels running to the clerestory walls. On the northern side
