=The Lantern-tower= has on each face two large windows with transoms, of three lights.  The tracery is that known as net-tracery.  Between these windows is a blank window, if the term may be allowed; the tracery exists, but there never was a window; it is in four divisions; while between the windows and the corner turrets are similar traceries of two parts.  The whole is surmounted by a parapet above a plain arcade.  The corner turrets are octangular.  As at present finished at the top there is undoubtedly an appearance of their being incomplete.

The west side of the =North Transept= is a very excellent specimen of Norman work; and we find less change here than in any other part of the cathedral that belongs to the same period.  The tracery of the windows is Perpendicular, but the windows themselves are otherwise unaltered:  at the top of all is a Decorated parapet, which is here composed of a series of quatrefoils; and the parapet to the corner turrets is not Norman.  As there is no aisle on the west side of this transept, there has been no alteration in the wall, as was the case with the nave aisles.

The north end of the transept is similar; but the shallow buttresses between the windows rise to a greater height, and there is another arcade above the upper tier of windows, and a blank arch in the gable.  The gable has crockets, and a cross at the apex.  The lower Norman window in the aisle here is unlike any others on this side of the church, but there are four others like it on the south.  The upper aisle window here is of three lights, with a large pointed trefoil above them instead of tracery.

The east wall of this transept is specially worthy of note.  We can trace the lines of the roof of the Lady Chapel which formerly stood to the east of the wall; and beneath this are two bays of the original triforium range, showing two of the simple Norman windows.  Between these and the roof are six Early English lancets.  Below are the upper parts of the two great arches which were constructed as an entrance to the Lady Chapel.  When the Lady Chapel was pulled down in the seventeenth century these were converted into windows filled with late tracery in imitation of Perpendicular work, and the lower part was walled up, except that a doorway was constructed.  This was afterwards blocked up for many years, and only reopened during the recent restoration works.  The same alteration has been effected in the western part of the choir aisle, the arches towards the Lady Chapel having been in like manner made into windows.  The lower window nearest the tower is a very graceful geometric window of three lights, exactly like the three in the south transept; the window above is of the same period as all the other Decorated windows of the triforium range.
