Under the second window from the chapel is an arched recess, which is thought to have formed an entrance to the church for the convenience of the sisters and others attendant on the sick in the Infirmary which stood near, but it has been closed on the exterior for many years. The interior may have been since used as a receptacle for relics; now it is occupied as a receptacle for a beautiful life-size effigy of Dr. Selwyn, for upwards of forty years Canon of Ely, and for many years St Margaret Professor of Divinity at Cambridge;[48] who died in 1875. The figure is represented as vested in cassock, surplice, and stole, with the hands joined as in prayer, in white statuary marble, and resting on a moulded base of Purbeck marble. The cost was defrayed by subscriptions from several noblemen and gentlemen formerly Eton scholars. [Footnote 48: The Professor left the sum of L10,000 towards the erection of Divinity Schools in connection with the University of Cambridge, which have just been completed.] Near this we may notice an ancient gravestone, or part of a monument found under the floor of the nave in St. Mary's Church, in 1829. It represents an angel with wings raised above the head, bearing a small naked figure, probably representing the soul of a bishop, as a crozier appears at the side; the angel has on a kind of cope with an ornamental border; and around the head is a large circular aureole, and the canopy shows a mass of buildings with semicircular arches. There is an inscription on the rim, "_St. Michael oret p' me_." To whose memory it was executed it is impossible to say, but it is doubtless of great interest. A good view of the organ may be had from this aisle by looking over the tomb in the fourth bay from the chapel. Several other monuments to former prelates of the church, and to other persons, may be observed in this aisle: one to Bishop Gunning (1675-1684), worthy of remembrance as the author of the "Prayer for all sorts and conditions of men." Near the foot of this monument is a piscina in the wall. A little further we find one to Bishop Heton (1600-1609), occupying the fifth bay, and is perhaps the only instance since the Reformation, of the effigy of a bishop in a cope ornamented with saints; the figures on the left border are those of St. Bartholomew, St. Matthias, St. Andrew, St. Peter, and St. John.
