On each side of the lady-chapel are five large windows of four lights each, with very beautiful tracery. Those on the north side have been thoroughly restored within the last few years. At the same time the cusps have been replaced in the large circles, of which two are over the head of each window. Between the windows are buttresses, necessarily large, to support the vast extent of the stone-groined roof. At the four corners are double buttresses, with much larger pinnacles, and two niches toward the top, the upper one shallow, but the lower deep enough to hold a statue, and with a projecting canopy. The east end is less decorated than the west. There was once, as it seems, some sculptured figure or figures in front of the upper part of the window, no doubt destroyed when the interior was mutilated. [Illustration: ELEVATION OF ORIGINAL BAYS OF BISHOP NORTHWOLD'S PRESBYTERY.] "The #East End# of the cathedral itself (Bishop Hugh's work) is a grand example of Early English."[12] Except for the windows of the chapels of Bishops Alcock and West in the aisles, and that the Early English lancets in the triforium range in the south aisle have been removed and a plain wall substituted, this eastern front is almost unaltered. It does not appear when this last alteration was made. In the view in Bentham, dated 1767, are represented lancets glazed and blank, exactly similar to those in the triforium on the north. The windows are all lancets, without any cusping. Their grouping is specially effective. In the centre, in the lowest stage, are three broad lancets of equal height, divided by shafts, and with deep mouldings, and with two sets of dogtooth all round. Below the string-course above are four deep quatrefoils. In the next stage the lancets are five in number, the central one being the tallest, while above the outer ones are trefoiled niches; and there are two six-foils below the next string-course. The upper stage has three lancets of equal height, which give light to the space above the stone-groined roof, with a small trefoiled arch, unglazed, and half of another on each side. In the gable are three large sunk panels, two of six cusps, and one of eight. The whole is surmounted by a large handsome cross, restored at the expense of Lady Mildred Hope. The large buttresses on each side of the central group of windows have four niches on each side, the three upper ones having bases to support statues; the upper and lower of these have trefoiled heads, the two others cinquefoiled heads. At the summit are sunk trefoils under the gabled tops; and a little further to the west, on the south, the whole is finished by an octangular turret with shallow arches and a pyramidal top with crockets.[13] The buttresses at the corners of the aisles have much loftier pyramidal heads. These have also crockets. The east end of the triforium range on the north is particularly good. The east window of Bishop Alcock's chapel, which was of course in existence long before
