[13] There is a further disadvantage, of a more material kind, in the encroachments. The smoke and soot from passing trains on one side, and the dust from a coffee-roasting establishment on the other, are having a sufficiently obvious effect on the fabric, as well as on the surrounding grass-plats. The latter require frequent renewal in consequence. [14] Perhaps the deflection is more frequently towards the north. [15] A converse instance of mistaken nomenclature occurs at Westminster Abbey, where the Lady Chapel is commonly called after Henry VII, who began its erection, in place of the earlier chapel, and is buried in it. In an inventory of 1538 the "Bishop's Chapel" at St. Saviour's is styled "the little Chapel of our Lady," which perhaps indicates that there was an altar to the Virgin in the retro-choir. Two Lady Chapels in one church are not unknown, as, _e.g._, at Canterbury Cathedral, where there was one in the north-west transept, now called "the Dean's Chapel," and another in the crypt under the high altar. A case more directly to the point may be quoted from Barnwell Priory, where the Lady Chapel is known to have occupied a similar position to the retro-choir at Southwark, with a "little Lady Chapel" appended to it. (_Vide_ "The Observances in use at the Augustinian Priory of Barnwell," by J. Willis Clark, and the accompanying plans.) [16] The pinnacle at the south end was removed a few years ago to prevent its falling. [17] The original number of bells, in 1424, was seven, and their names were Nicholas, Vincent, St. Lawrence, Anna Maria, Stephen, Maria, Augustine. In the same year the bells were increased in weight and one more added to the number. The names were then changed, and became Christ, St. John-the-Evangelist, All Saints', Gabriel, St. Lawrence, Augustine, Mary, St. Trinity. They were recast, with 64 cwt. of fresh metal, in 1735, when the peal was brought up to its present number. More recently the two largest of the treble bells (D# and C#) were slightly reduced in weight. [18] The builders of 1839 fortunately contented themselves with building round the bases of the piers, which they left on the old foundation. [19] _E.g._, in the will of Joan de Cobham, dated 1369, the testatrix expresses her wish to be buried before the door of St. Mary Overie, "where the image of the Blessed Virgin sitteth on high." It will be noticed that this is the principal feature in the Priory seal. [20] Drawings of the Perpendicular doorway are given by Moss and Nightingale (1817-1818), and by F.T. Dollman (1881). The ruins of the old nave, including this fine doorway, were finally removed towards the end of 1838, to make way for the _pure Gothic_ structure (as it was called in the newspaper descriptions of the day), which was commenced in the following year.
