the old windows were continued round the later buttresses. In the
fourth bay, above the point of the window arch, the curve of the
original apse of the ambulatory is just traceable; but beyond this
point eastwards the twelfth-century walling has disappeared until we
meet it again in the lady-chapel. There is a small buttress in the
fourth bay marking the junction between the two periods of masonry. In
the second and third bays part of the twelfth-century top to the aisle
walls remains. The roof may have had eaves originally, but now there
is a parapet of about the same date as the present buttresses; and the
projection of this parapet is carried upon the corbels that were
carved and built in before the second fire occurred. The space between
each corbel is bridged over by small single stones cut out to the
shape of a semicircular arch.

The windows in the second, third, and fourth bays differ in size and
shape from each other; that in the second bay has a pointed arch and
no tracery, square abaci and the remains of carved capitals. The angle
shafts and bases are gone. They were all inserted at about the same
time; but that in the third bay has had some poor modern tracery
without cusps added to it, and that in the fourth bay is a more
recent, insertion than the one next to it. In the third and fourth
bays just above the low chamfered base of the wall are three
semicircular markings cut on the wall, but there is nothing to explain
their existence. In the fourth bay close beneath the sill of the
window is a stone built into the wall, upon which a dedication cross
is cut. At the fifth bay the east walk of the cloisters joins the wall
of the aisle; its roof partly hides a window, above which is a square
panel of the fifteenth century. This panel indicates the position of a
window, for the jambs and mullions of its tracery may be seen within
the church. They are rebated for shutters, the old hooks for which
