_Photochrom Co., Ld., Photo._ The *Organ*, which occupies the first archway on the south side of the choir, contains work by Renatus Harris. Mr. Phillips Bevan(4) writes of it, "It was the gift of Charles II., and was very nearly destroyed by the fall of the central tower. It has twice been enlarged since, once by Gray and Davidson, and lastly by Willis. It has 16 great organ stops, 11 swell, 7 choir, 7 solo, 8 pedals, with 2672 pipes. A great feature in Willis’s improvements is the tubular pneumatic action, which does away with trackers and other troublesome internals. Sir F. Gore Ouseley having been precentor of the Cathedral, it goes without saying that he made everything about the organ as nearly perfect as possible, and, for the matter of that, no lover of music should omit to hear the _Unaccompanied_ service usually held on Friday morning." In the south wall of the south choir-aisle are four Decorated arched recesses containing four effigies of bishops, belonging to the Perpendicular period. These effigies have been attributed, beginning from the west, to R. de Melun, 1167; Robert De Bethune (died 1148), the last Norman builder; Hugh Foliot (died 1234) or Robert Foliot (died 1186); and William De Vere (died 1199). On the north wall under an arch opening to the choir is the tomb of Bishop De Lorraine or Losinga (died 1095), who superintended the building of the fine west front of the cathedral so unfortunately destroyed. This effigy also belongs to the Perpendicular period. The large size of the ball flower and fine wood-carving of the Decorated period on these tombs is noticeable. Between the two eastern piers of the choir is the fine effigy and brass to Bishop Mayhew, of Magdalen College (1504-1516). The effigy is wearing a mitre, and is fully vested. In front of the monument are panels filled with figures of saints, and over the effigy is an elaborate canopy, which has been restored. In the last bay to west of the south choir aisle a door gives access to two Norman rooms, used as vestries or robing rooms, to enter which you pass beneath the bellows of the organ. Exhibited in cases in one of these rooms are some of the treasures of the cathedral, ancient copies of the Scriptures, chalices, rings, etc., described in detail towards the close of this section. A two-storied eastern chamber was added to the Norman work in the Perpendicular period, and was used as the cathedral treasury. Before leaving the south choir aisle the old stained glass windows with figures restored by Warrington should be noticed, and the celebrated *Map of the World* is well worth some study. It was discovered under the floor of Bishop Audley’s Chapel during the last century, and appears from internal evidence to have been probably designed about 1314 by a certain Richard of Haldingham and of Lafford (Holdingham and Sleaford in Lincolnshire).
