light upon the choir altar, the shrines in the neighbourhood, and Bishop Barnet's tomb under the pier arch, which is beneath one of these windows. Fortunately the experiment was not repeated. After some time had elapsed, the changes above indicated were carried out; the low Early English triforium outer wall was removed, and the loftier Decorated wall and windows erected. In the extract above given it looks as if the removal of the triforium roof, putting a lead roof to the aisle below, and turning the triforium arches into windows, were confined to these two bays on the south. But the same thing was also done in the two corresponding bays on the north. But there, when the later raising of the triforium walls took place, this raised wall was continued over the two bays in question; and we do not now see there any remains of Early English work. [Illustration: THE PRIOR'S DOORWAY. _Photochrom Co. Ltd. Photo._] In the east wall of the #South Transept# are broad, geometrical windows of two lights each. At the top of the southern face of this transept, deeply recessed, is an extraordinary Perpendicular window of seven lights. There seems no record of this being constructed. By the remains of corbels in the lower part of the wall we see that there was once a covered passage here, no doubt connecting the cloister with the chapter-house. Beyond the transept are three Norman doors of exceptional interest. One, indeed, is in the west side of the transept, and must have been the original entrance here into the church. It is now quite blocked up with stone. It has only recently been discovered. There are remains of two Norman doors, the lower, with enriched mouldings and shaft, being considerably later in date than the round arch above it. This latter has the nail-head ornament. The northern end of the arch is concealed, as well as the eastern end of the adjoining door into the south aisle, by a mass of masonry built for a buttress. The door into the south aisle is known as #The Monks' Door#, and is the regular entrance into the cathedral from the south. It opened from the eastern walk of the cloister. It is of later date than the wall in which it is placed. The ornamentation is very rich; one spiral column is especially noteworthy. There is a trefoiled arch, the cusps having circular terminations with the star ornament. In the spandrels are quaint, crouching monks, each holding a pastoral staff. Above are two curiously twisted dragons.
