small
single-light windows. These narrow and sharp-pointed windows are
peculiar. The arch-moulds are different from the other work of the
same date in the church. There is no sign of tracery in their design,
and the jambs have a simple attached shaft in the outer reveal. The
bases to these shafts are earlier than those of the shafts to the
south aisle chapel windows, and the edge of the inner member of the
window arch is merely cut off with a straight chamber. There is one
window, the same as these, hidden in the west walk of the cloister.
Beneath the windows just described there are two small single-light
openings in each portion of walling on either side of the central
buttress. These six windows serve to light the vaulted (sacristy)
choir school within.

It has been supposed by some that a chapter-house once existed within
the paradise close by the west angle of the transept. The south end of
the transept rises on the north side of the cloister garth. At the
south-west angle a great part of the twelfth-century masonry in the
broad flat buttresses remains. The south-east angle and buttresses are
quite different. They are perhaps part of the work done during the
thirteenth century, though it is possible that they were introduced
when Langton inserted the large south window of the transept. This
window has been very much restored since the seventeenth century, when
it was almost knocked in pieces. Wooden props served instead of
mullions for many years to hold up the tracery above. The repair that
has been effected retains the old design. Above each angle of the
transept is a turret, octagonal in form. Neither of them is complete.
They were only required in the fifteenth century as a means of access
to the roofs at the parapet level from the staircases in the angle
buttresses. The gable of the transept rises above the parapet just
described, but it is not in the same vertical plane as the face of the
wall below. The top of this gable was for many years in a very wrecked
condition. The design of the tracery in the rose window is in two
orders, based upon equilateral triangles filled in with cusps.

Close to the ground on the south-west corner buttress are two
string-courses. The lower of these is a billet-moulded course cut,
like those to be seen on the south-west tower. Its presence here, and
at this level, shows that this was the original le
