specially observable in the vaulting, the vaults of the transept having to be carried on arches which rest on corbels, inserted in the arches of the aisles, in an awkward manner (see Fig. 829 and Fig. 841). The east window of the north transept, which had been long obscured by a structure built against it, was recently discovered and opened up. It is of good, but late, decorated work (Fig. 842), and probably gives an idea of the mullions which, no doubt, formerly existed in the windows of the nave and choir, but which have been removed and traceries of 1829 substituted. The details of this window, as shown in Fig. 842, are the only original window details now remaining in the church. The window is of three lights, with an arched transom ornamented with battlements, like some windows at Melrose. In the interior very elaborate niches were found, with ornamental canopies, which have been unfortunately much destroyed. Over the windows, on the outside, there were in position two corbels, supporting the wall-head parapet. As these would have been concealed by the vaulting of the Chambers aisle (which was recently inserted), they were built into the piers at the arch springers of the entrance to that aisle. Amongst the rubbish cleared out in opening up this window, a rude Norman capital was found built into the wall. The north transept was considerably widened, in 1829, by setting back the west wall and wheel stair. A portion of the old arcading is still visible at the break on the west side.
