The apartment next the sacristy is 28 feet long by 11 feet wide. It has now been appropriated as a mausoleum, but may have originally been a parlour. There is an ambry in the south wall near the east end. The doorway is semicircular, and of Norman character (see Fig. 412). The east window is plain, and consists of two round-headed openings enclosed in a large semicircle (see Fig. 411). The above two apartments are on the level of the cloisters; but the floor of the chapter house, which is next in order, is several feet below the level of the cloister walk. The ordinary central doorway and side windows opening from the cloister (see Fig. 412) are, however, placed in their usual position on the level of the cloister walk. The door is thus some five feet above the floor, and if the doorway was used for access to the chapter house, it must have been provided with a stair down, of which there is now no trace. The [Illustration: FIG. 412.--Dryburgh Abbey. Transept and East Side of Cloisters.] [Illustration: FIG. 413.--Dryburgh Abbey. Doorway of Chapter House.] [Illustration: FIG. 414.--Dryburgh Abbey. Interior of Chapter House.] side openings were unglazed, and were used for seeing and listening to what was proceeding in the chapter house below. The doorway (Fig. 413) is large and deeply recessed, having three shafts on the sloping ingoing, and plain mouldings above in the round arch, divided into several orders. The jambs and arch over them are enriched with a bold dog-tooth moulding. The outer arches of the windows on each side of the doorway are plain semicircles, filled in with two pointed lights, having a central shaft. [Illustration: FIG. 415.--Dryburgh Abbey. Carved Figure in Chapter House.] The chapter house is 48 feet in length by 23 feet in width, and retains its round barrel vault (Fig. 414), which is about 20 feet in height. It has three pointed windows in the east end (see Fig. 411) and two similar windows in the side walls, where the chapter house projects beyond the general line of the buildings. In the interior a round arched arcade runs along the east side, supported on single shafts, and there are traces of a similar arcade having run round the side walls. There is an entrance doorway in the south wall, which is probably not original, and the approach to it has been modernised. The east gable wall over the chapter house still exists (see Fig. 411.) It has simple flat buttresses of a Norman type at the angles and between the windows, but the pointed arches indicate transition work. Amongst the fragments of carved work preserved in the chapter house is that shown in Fig. 415. It represents the pascal lamb slain, [Illustration: FIG. 416.--Dryburgh Abbey. South-West Angle of Cloisters.] and is surrounded by a wreath of foliage, above which are the letters I H S. The vine leaves flowing from the lamb may represent the branches springing from the true vine.
