nt foliated capitals: above these is a string
course of rosettes, forming the base of the parapet. Thus far the two
turrets are strictly uniform; but in the parapets, by which they are
surmounted, and in the pinnacles, which terminate the clustered shafts,
there is a marked difference.

"The parapet of the north turret consists of the wave ornament, with
double featherings and intersections: the pinnacles at the angles are
hexagonal, corbelled at the base of the pyramid with human heads, and
finished above with crockets and finials.

"The parapet of the south turret contains a series of quatrefoils,
while the pinnacles at the angles are beautifully blended with the
clustered shafts, so as to form a regular and continuous course and
termination; the mouldings are carried up in high pointed pediments,
and from these a cinquefoil arch at each angle, surmounted also by a
pediment, with a quatrefoil in the spandril, connects them with the
spire in the centre, and sustains a lofty triangular pinnacle, which,
like the pediments below, is decorated with crockets and a finial. In
this respect the south spire differs from the other, which has no
connection with the side pinnacles. Both are pierced with pointed
windows in two ranges, four in each range, divided by mullions, and
crowned with crocketted pediments; and the apex of each is terminated
by a finial and a cross, included in the extensive repairs carried on
by the present dean[27] and chapter.

"The style of these spires, with the parapets and pinnacles, marks them
out as a later work than the turrets beneath; and we may infer from the
similarity of their details to those of the porch, that they formed a
part of the repairs and alterations which the whole front appears to
have undergone when the appendage was inserted; and when the central
window of the nave was enlarged, and that, and the others which now
enliven the inner wall, were filled with perpendicular tracery. The
porch is vaulted with stone, and is entered by an obtuse arch, over
which is an elliptical window, divided by mullions into six lights
under cinquefoil arches, which are again subdivided in the head into
lesser arches.

"The spandrils formed by the curve of the arch, and the base of the
window, are enriched with circles, clasping shields of arms, and
rosettes with other devices. The arches and windows are bounded by
buttresses, which are broken by offsets and empannelled with niches.
