There is an allusion to a recognised vestry in Leland, and very possibly the present room is meant; if so, it would seem from his account to have been used also as a library. But the fact remains that the church possesses no vestry except what is obviously a disused chapel. =The Lady-chapel= or Lady-loft is 23 feet 3 inches wide, and 68 feet long.[118] Its west and north sides, being formed by what was once the exterior of the church, display not only windows and buttresses, but also a string-course with gargoyles. From the west wall projects one of Archbishop Roger's buttresses, terminating in a slope, between the two blocked windows of the Mallory Chapel, which resemble the aisle windows of the other transept. The window on the right, mutilated by the insertion of the doorway, has lost its shafts, and retains only their capitals. The other window is partly cut off by the south wall, and is now a cupboard. In the north wall, the first three bays are Archbishop Roger's, and the windows resemble in their treatment the two just described, and are separated from each other by two buttresses which terminate, like those on the opposite side of the choir, in two slopes one close below the other. There is a third buttress, terminating in a single slope, at the angle formed with the transept. The Decorated window in the fourth bay is treated in the same manner as the rest of those in the eastern portion of the choir-aisles, and the Decorated buttresses which flank it are those which have been followed up from the crypt. The rich string-course or cornice along the top of this and the west wall corresponds with that on the other side of the church. The gargoyles are of course Decorated, and so is the string-course itself, eastwards at any rate of the second gargoyle on the north wall, for here one of the mouldings has a fillet upon it. Whether the rest of the string is Archbishop Roger's work or not, it is difficult to decide.
