It is interesting to have this record, for the spire during the following century was still a cause of trouble. Spershott's memoirs show that about 1725 "a new chamber organ was added to the choir of the cathedral, the tubes of which were at first bright like silver, but are now like old tarnished brass." Whether this organ contained any parts of that which was destroyed in the previous century is not known; but many old prints and drawings show that the case of the one that was now built on the top of the Arundel screen was quite as beautifully designed as the one in Exeter Cathedral, or King's College Chapel at Cambridge. About 1749 the Duke of Richmond's vault was "diged and made" [23] in the lady-chapel, and ten years later "the kings and bishops in the cathedral" were "new painted." The floor of the lady-chapel was raised to give height to the vault beneath, and a fireplace and chimney built up in front of the east window. Portions of the other windows were plastered up, and so left only partly filled with glass. These served to provide light in what was now to be the library, since, apparently, the originally well-lighted library, above the chamber now used for the purpose, had lost its proper roof and been otherwise made useless. [23] Spershott. There is little else to be said concerning the history of the building during eighteenth century; but it is stated by a careful observer, [24] writing in 1803, that "in the interior of this cathedral few innovations have been effected." He says that the east window of the lady-chapel is plastered up, and that "we find that the great window in the west front of the cathedral has a short time back had its mullions and other works knocked out, and your common masoned 'muntings' (mullions) and transoms stuck up in their room, without any tracery sweeps or turns, of the second and third degrees; which work may before long be construed by some shallow dabblers in architectural matters into the classical and chaste productions of our old workmen. On the north and south sides of the church are buttresses, with rare and uncommon octangular-columned terminations; but they have likewise, to save a trifling expense in reparation, been deprived of their principal embellishments, and are now capped with vulgar house-coping.... "It may be well to speak of the west porch as an excellent performance; and the statue over the double entrance is remarkably so." [24] _Gentleman's Magazine_, Part I., 1803, pp. 22-25. Proceeding, the same writer relates that:
