fifteenth-century windows. They are not placed centrally over the
others below. In design they are each divided into three lights by
mullions. On the east side of the middle buttress is an old rain-water
head of (eighteenth-century?) leadwork. Part of the lead piping still
remains, having the old ears to fasten it to the walls. The west side
of this chamber has one buttress on the south angle and a window in
the centre of the wall. Above it is the low slope of a gable. The
window is similar to those on the south side, but the head is a
pointed and four-centred arch. The mullions have been restored. Below
the part just described is the earlier work of the thirteenth
century. It rises as far up as to the string-course formed by the
continuation of the abaci of the capitals in the two 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
