These two chapels were the private property of the Earls of Derby, who had to keep them in repair. In the second half of the eighteenth century the roofs needed extensive repair; this was done by the thirteenth Earl of Derby in conjunction with the townspeople of Manchester, and the Earl surrendered his rights to the chapels, handing them over to the parishioners on condition that he and his successors should no longer be held responsible for keeping them in repair. The Derby Chapel is now fitted with an altar at the east end, a font on the north side, and oak benches, so that it can be used for week-day services when desired. The Ely Chapel is not fitted in any way.
St. James' Chapel, or the Ducie Chantry, and the Chapel Of the Holy Trinity, which formerly occupied the east and west ends of what is now the outer north aisle, and were founded, the former in 1507 and the latter by W. Radcliffe of Ordsall in 1498, have no longer any separate existence; the only sign of their having been chapels that remains is a piscina in the pier at the south east corner of St. James' Chapel. The arcade between the outer and inner north aisles originally dated from about 1500.
The North or Craven Porch is opposite to the south porch and bears a strong resemblance to it. It consists of two bays, each vaulted in stone in the same manner as the bays of the south or Jardine Porch; a door to the east side of the inner bay leads into the registry office.
It now remains to examine the Central Nave and Choir. This church differs from most of our cathedral and abbey churches in having no triforium.[!--note--][2] And the clerestory is not lofty, so that the church is rather low for its width,[!--note--][3] though the height of the arches of the main arcade prevents this being felt. The roofs of the aisles are all modern, but that of the nave, though extensively repaired, has much of the original work in it, and, with the exception of a few bosses, the choir roof is old. All the roofs are of timber; in the nave the intersections of the main beams are covered by beautiful bosses carved out of the solid wood. On either side, at the points from which the main cross beams spring, is a series of angelic figures splendidly carved in wood: those on the south side playing stringed instruments, those on the north side wind instruments.
The choir roof is more ornate; the panels between the beams are filled with tracery; the bosses here are differently constructed from those in the nave; here each leaf was separately carved and then nailed in its place. At the time of the restoration this roof was skilfully repaired by introducing new beams above the old ones and fastening the old to the new with bolts.
The pillars of the main arcade of the nave are modern work built in imitation of the original ones. They are light and graceful, and like many other pillars of fifteenth century date, are formed of shafts of which only half have separate capitals, the other mouldings running round the arch. The spaces between the arches are elaborately carved with heraldic shields.
