To the south of the south transept some portions of the slype or passage from the cloisters to the eastern side of the monastery, and parts of the chapter house, yet remain. The slype has a plain semicircular arched doorway (see Fig. 507) next the cloister, and has had a stone bench or seat running along each side. The passage has been arched with a cradle vault in ashlar, of which a small portion still survives. The chapter house is in ruins, but the west wall (Fig. 506), which contains the semicircular entrance from the cloister and two semicircular windows, one on each side of the entrance, is still preserved. The windows were divided into two openings by a mullion and two plain arches. The doorway and double windows have numerous mouldings, and the doorway is enriched also on the inside (Fig. 507.) The mouldings are bold, and the same mouldings are repeated in the jambs and arches. The caps are simple (see section in Fig. 506), but they are not adjusted to the mouldings of the jambs, having a plain soffit, against which the shafts and mouldings of the jambs butt. These are all indications of somewhat late design. As was usually the case, the doorway and side windows of the chapter house were left open; that is, without a door to close the doorway or glass in the windows, so that all that passed in the chapter house might be seen and heard from the cloister. The chapter house has been of quadrangular form, 19 feet in width by 38 feet 4 inches in length. Only the entrance front remains. [Illustration: FIG. 504.--Kilwinning Abbey.

The eastern angles terminated with massive buttresses. The extreme external width over the bases was only 42 feet 6 inches, thus leaving a choir not more than 30 feet in width internally. From the massive foundations discovered at the intersection of the nave and transepts, it is surmised that there may probably have been a central tower as well as the two western towers. DUNBLANE CATHEDRAL,[39] PERTHSHIRE. The dioceses of Dunblane and Brechin were founded towards the close of the reign of David I. from the remains of the old Pictish bishopric of Abernethy, after numerous portions had been abstracted by St. Andrews.[40] The town of Dunblane stands on the left bank of the Allan Water about four miles north of Stirling. The old town is small and consists of a single narrow street leading from the bridge over the Allan up to the platform on which the cathedral stands surrounded by its ancient churchyard. Indications of the age of many of the houses may be observed in the coats of arms inserted in their walls.
