In the north transept the moulding between the clerestory and triforium
is dog-tooth. It is plain in the south transept.

The arcades of the aisles are practically the same in both aisles,
except for the differences noted between the east and west aisle of the
south transepts.

There are two rows of dog-tooth moulding round the windows in the aisles
of the north transept, but only one in the south.

The clerestory shafts in the aisle of the north transept are bolder than
in the south, and the capitals, especially on the east side, are more
elaborate and beautiful.

The extra Decorated pillar on the west side of the north transept has
already been noted.

The ends of the transepts are, of course, entirely different in
arrangement. Purbeck marble is used lavishly all over the transepts; as,
for example, alternately with stone in the main piers, on the shafts of
the aisles, and in the triforium and clerestory. The main vaulting
shafts are altogether of Purbeck.

The arcade at both ends of the transepts is entirely without Purbeck
marble.

In the south front the shafts of the lowest row of windows are
alternately of Purbeck and stone. The arcading above the door is wholly
Purbeck, with dog-tooth mouldings of stone. The shafts of the central
windows are Purbeck with alternate dog-tooth mouldings, and there are
Purbeck shafts at the side of the rose window.

There are also Purbeck shafts on each side of the door, beginning above
the arcade below.

In the north front, the shafts of the five sisters and of the five
lancets above them are alternately marble and stone.

As has been said, the proportions of the bays in the transepts are very
different to those of the nave. The triforium is much larger, and the
clerestory much smaller. The main arches, slightly smaller in proportion
than those of the nave, are extraordinarily rich and beautiful in
detail. Their mouldings are very complex and deep, and are varied with
dog-tooth and billet ornament.

The piers are perhaps too thin, though beautiful enough in themselves.
They are made up of alternate shafts of Purbeck marble and stone. Those
of Purbeck are ringed half-way up. The Decorated piers are altogether of
stone, and not ringed at all. The arrangement of the shafts is not quite
so bold and various as in some other Early English work--the choirs of
Ely and Worcester, for example.

The capitals are finely carved, though small. Those in the north
transept
