are very finely carved, and, as was usual at the time, are very deeply under-cut; and the dripstones terminate in very interesting corbels in the form of heads and bunches of foliage. Recently, on the west side, some of the arcading has been opened out to afford access to the new vestry, which has been constructed by roofing in the space between the vestibule and the north transept. On the east side near the cathedral is the entrance to the library, which is the upper storey of the chapter-house building, and is approached by a spiral staircase. At the farther end, on the same side, is the very fine entrance to the chapter-house. This, like the central west doorway and that in the north transept, is double and recessed. The mouldings in the arch are deeply and finely cut, and the capitals of the grouped shafts are very richly carved with delicate leaves. The jambs have an enrichment of dog-toothing behind the slender detached shafts, and the two small arches have trefoil archivolts, so that the whole has a very rich effect. In the tympanum of the arch there is a bas-relief figure of Our Lord in a quatrefoil recess. [Illustration: EASTERN PORTION OF THE ARCADE IN THE CHAPTER-HOUSE.] The chapter-house is a very fine room; it is octagonal in shape, but the north and south sides of it are double the length of each of the other six sides, which are equal. There is a central pillar, the clustered shafts of which are banded in the centre; the capitals of these shafts have a particularly rich and elaborate carving of foliage; and above, the vaulting ribs spread to the roof like the branches of a tree, producing a very fine effect. The bosses where the ribs intersect are also worthy of attention, and the ribs rise from very richly-carved and deeply-moulded corbels. The windows are Early English, and of two lights each. Below is a very beautiful arcading, similar, indeed, to that in the vestibule, which entirely surrounds the building. The arcade is composed of deep, moulded, trefoil arches, resting on single columns, with beautifully-carved capitals, in some of which will be found figures of birds and animals. The canopies of the arches are dog-toothed, and end in curiously-carved heads, which afford interesting illustrations of the head-dresses of the time.
