l the inadequate size of the tower by the
addition of two turrets can be best studied from this side.

The North Aisle of the #Choir# consists of eight bays, all Early
English, except the easternmost one (the retro-choir), which is Late
Decorated; while the western bay has a Perpendicular window.

Sometime in the fifteenth century the third bay from the east, in each
aisle, was altered and a large Perpendicular window inserted in order to
admit more light to the sanctuary. During the restoration of the
cathedral these later windows were removed, and replaced by careful
copies of the other Early English windows.

The basement is composed of bold mouldings with a plain wall equivalent
in height to the internal wall arcade. Over this, a string-course runs
uninterruptedly round the choir just below the windows.

Each compartment has an arcade of four lancet-shaped divisions, the
external ones blank; while the internal divisions (which are wider than
the others) form the window. The slender, banded, shafts are detached,
which is rather unusual, and have moulded bases and capitals. The bands
divide the shafts into unequal lengths, the lower portion being the
shorter. The arch mouldings are good. Owing to the fact that the blank
arches are more acutely pointed, their outer mouldings terminate higher
than the mouldings of the internal arches.

Towards the east end small heads, and bosses of foliage, ornament the
junction of these mouldings. Above these the cornice and parapet rest
upon blocks bearing the nail-head ornament.

The second bay from the east is divided into three equal spaces, with a
very narrow acute angle on the right.

A series of fine gabled buttresses gives relief to the exterior of the
choir on each side.

The windows of the #Clerestory# have very rich mouldings, and also
afford fine examples of flowing tracery. Each bay has an arch with three
divisions, the central one higher and wider than the others. On this
side only--the north--the base is ornamented with trefoils.

There is a cornice above the windows extending from the tower to the
east end. It is richly decorated with heads and the ball-flower ornament
which is characteristic of fourteenth-century work. It is broken here
and there by gargoyles projecting almost three feet from the wall. The
parapet makes but a poor show in comparison
