The Organ.—On the south side of the aisle is the organ-chamber erected by Sir Arthur Blomfield and Sons, after much discussion as to a suitable place for the new instrument, for which it was eventually decided to build the chamber over part of the site once occupied by the Magdalen Church. The old organ used to stand in the gallery at the west end of the debased nave, and was since removed to the north transept. When it was finally taken down it was unsaleable as a musical instrument, and had to go for what it would fetch as so much wood and metal. Some relics of it have, however, been preserved in the shape of the large gilded angels which adorned its front. These are now stored above the tall iron safe in the Harvard chapel. The present organ and the chamber which contains it were both presented by the late Mrs. Robert Courage as a memorial to her husband.

The new organ, built by Messrs. Lewis and Co., Limited, is of peculiarly rich and pleasant tone. It contains more than 4,000 pipes and consists of four manuals, with a system of interchangeable composition pedals, the whole embodying the most recent improvements for altering and combining the stops, and working the instrument to the best advantage with the least exertion. The action is electro-pneumatic, and the wind is supplied by a rotary hydraulic engine.[31]

Imbedded in the pavement at the entrance to this aisle there is an interesting collection of Roman tesserae, which have been carefully preserved as an evidence of the antiquity of the site.

The Tower.—A great difference is to be noticed between the arches of the east and west sides and those of the north and south. The former are evidently of the same age (thirteenth century) as the nave and choir, while the others indicate that the transepts were not built till the following century. There is an important difference also between the north and south arches, in that the shafts of the former stop considerably short of the ground, whilst those on the south are carried down to the pavement.

The moulding of the western arch is supported by the heads of a king and queen (uncertain), and on the southern side of the eastern, or choir, arch there is the head of a bishop.

Above the arches there is an open arcade on the four sides of the tower, which communicates with the roof above the nave, choir, and transepts. The comparatively modern ceiling, which limited the view upwards within the tower, has now been removed, and the roof raised to its original level beneath the ringers' floor. This new roof is of oak, in which some bosses from its fifteenth century predecessor have been inserted. Pendent from it is the fine Chandelier of wrought iron and brass, presented to the church in 1680 by Dorothy Applebee, who was buried within the sanctuary two years later. This chandelier had been transferred to the choir during the degradation of the old church, in which position it was by no means without precedent in ancient churches, but its original place here was in the tower, to which it has been restored.

Sir Arthur Blomfield's work included the complete restoration of the tower windows and the interior walls.

The Pulpit comes from a relative of the Rev. W. Curling, the chaplain commemorated in one of the Lady Chapel windows, and is intended as a personal memorial to the same man. It is a delicate piece of carved oak, somewhat out of character with the massive stone-work around it, and is approached by a staircase still more slender in appearance. The carving, however, is well executed, and many notable sermons have already been preached from it, which, thanks to the sounding-board, have been tolerably well heard throughout the church.

The Lectern was presented by Mrs. Richard Hunt, in memory of her husband. It is of bronze with a brass pedestal, and represents an eagle holding a dragon in his claws.

The North Transept differs materially from the south in the dimensions and character of the windows, which in the south transept are larger and more elaborate. In the north transept there are three on each side, those next the tower being simple lancets, the others of two lights without tracery. All these at present contain plain glass. The two-light windows are exact reproductions of the originals, from fragments of which they were first restored by Mr. Wallace in 1833. The exceptionally large window on the north side is the gift of Mr. F.L. Bevan, and was unveiled by the Duke of Connaught on 22nd June, 1898, in double commemoration of the Prince Consort and the Diamond Jubilee of Queen Victoria. The present window, by Mr. Kempe, takes the place of an inferior one set up in 1861 to the memory of Prince Albert shortly after his death.
