It has been already stated that the baptistery which occupies the western end of the outer southern aisles is entirely modern, as also is the south porch. At one time a small porch called Bibby's Porch projected from the second bay from the west of the true south aisle, to the east of which, stretching right over the outer south aisle, was the Chapel of St. George. This occupied two bays, and projecting from it to the south was Brown's Chantry. To the east of St. George's Chapel, also occupying two bays, was the Chapel of St. Nicholas, the Trafford Chapel. These were the chapels on the south side of the nave aisle. Opposite to them, outside the north nave aisle, were two chapels, that of the Most Holy Trinity at the west, that of St. James, otherwise known as the Ducie Chapel, at the east end. The west wall of the outer nave aisle on the north side is original, so that the whole length of the series of chapels on this side was greater than that of the series on the south side. The nave and its twin aisles, as will be seen from what has already been said, consist of six bays. The eastern half of the church also consists of six bays, and the choir aisles, like those of the nave, are flanked by chapels which have fortunately remained undestroyed down to the present day, enclosed by their original screens. On the south side, raised three steps above the level of the nave and occupying three bays, was the Jesus Chapel, now divided into two parts, the western bay being used as a vestry, the two others as the Cathedral Library; from this a door leads into the chapter house, the main entrance to which is from the choir aisle. With this the unbroken series of building attached to the south side of the church ends, but from the easternmost bay a doorway in a screen opens into the Fraser Chapel, built as a memorial to her husband, the second Bishop of Manchester, by Mrs. Fraser. Crossing the church by the ambulatory, passing the small Lady Chapel, we find the whole length of the outer aisle on the north side occupied by the chapel of St. John the Baptist, often called the Derby Chapel. The western bay forms the antechapel, from which we pass into the chapel itself through the original oak screen. From the second bay, counting from the east end of this, the Ely Chapel projects.
