The interior of the choir (Fig. [1147]) is extremely simple. It is roofed with a pointed barrel vault, the surface of which, towards the east end, is ornamented with moulded ribs. These ribs spring from corbels in each angle of the apse and in the side walls, and extend to nearly the centre of the choir, where they cease, leaving the remainder of the vault plain. The idea has apparently been, by the introduction of these ribs, to make the presbytery somewhat ornamental. The windows, being below the

springing of the vault, are necessarily low, and the vault is in consequence dark. There are a plain sedilia, with elliptic arch, and an ornate piscina (Fig. [1148]) at the east end of the south wall. Opposite them in the north wall a monument (Fig. [1149]) under the north-east window contains, in an arched recess, an effigy, probably that of the second Lord Seton, who erected the church into a college. The choir is now roofed with wood and slates above the vault, but it was no doubt originally
