The original fabric--of which the choir with its aisle and two apsidal chapels thrown out from the aisle, and the south transept and one and a half bays of the north, are all now remaining--is of the earliest pointed, with occasional round arches to windows, etc. The character is very simple and mainly remarkable for the great beauty of the profusion of sculptured capitals to all the shafts. The section of the piers is singular and gives great lightness of effect; they are in fact thin slices of wall, and not piers formed in the usual way, and as the weight of them is not a crushing weight, I look upon them as excessively scientific in their arrangement. The triforium is very lofty as compared with the rest of the design, and consists of a very simple arcade of pointed arches, supported only by long and slender shafts set near together. The groining is good, and in the chapels a small shaft rises from the capitals for some feet and carries the wall rib: this gets over a difficulty in mitring the mouldings. The Lady-chapel appears to have been remodelled at a later day but upon the foundation of one coeval with the choir. A very grand effect is produced by the great size of the transepts--which have aisles on both sides--and by the placing of a chapel in the re-entering angles between them and the choir-aisle. In this way an internal effect of lightness and space, of very fine character, is obtained. One of the most remarkable features about this cathedral is, however, the extent to which, in later days, the old design was persisted in: _e.g._ the remarkable triforium is carried round the entire church, varied a little in its details and quite different in its sculpture, but still evidently a copy and from its great size giving an air of great unity to the whole design. In the clerestory windows generally there is a good deal of poor flamboyant tracery with a little glass of the same date, but in the choir the original windows all happily remain. These are, in the apse, rather wide lancets, and in the rest of the clerestory simple triplets. In the aisle there were windows of two lights with a simple quatrefoil above. Many of the windows have the dog-tooth ornament round the external labels. The choir still retains on the outside a very fine and original corbel table. In a chapel south of the choir are extensive remains of some most singular work for pavements--they are squares of stone slightly sunk in regular patterns and then filled in with some very hard black or red substance. The same work is carried up against the walls of this chapel, and in other parts of the cathedral are several small fragments of similar pavements. The stone is of a yellow colour and the system seems to admit of being turned to most useful account.
