 Part of the crossing, however, is probably older; but the other portions of the crossing seem to have been rebuilt at a late date, as the following indications show. The original arches of the north and west sides have no mouldings, but are only chamfered, and the caps, so far as visible, have an ancient character. The north arch has, at some period, been strengthened by the insertion of additional piers, and an additional arch within the then existing piers and arch (see Plan). The old arch is distinctly visible in the wall, and portions of the old piers are also exposed to view.

The arches of the east and south sides of the crossing are of a different character from the above, the arches being fully moulded. The piers (Fig. 998) do not differ much from those of the older sides, and are all of an early form of design. The same character is kept up in the inserted piers of the north arch, although these must undoubtedly be later than the original piers. The mouldings seem all to have been imitated from early forms (such as we find in the choir arch of the nunnery). The changes in the plans of the piers and mouldings, common in the central districts of the mainland, would be long in reaching this distant spot, and the old forms appear to have been, therefore, adhered to. Such continuations or imitations of early forms are very common in Scotland. It
