Back to back with Nos. 29, 30, and 31 lie Nos. 32, 33, and 34, with doorways opening west. The vaults of these six chambers are well preserved. Plate 68, Fig. 1, shows the interior of No. 31 with an arched ṭâqchah in the wall. The vault is ovoid and oversails the wall. The courts in the south wing of the palace correspond neither in size nor in disposition with those of the north wing. Opposite to the door of No. 18 a door leads into No. 35, which is an isolated chamber with a deep niche at the south end. Court I can be approached from court D only by a circuitous route through passages 17 and 45. Upon the east side of court I lie the two rooms 36 and 37, 4·40 metres wide and respectively 7·85 and 8 metres long. On the south side there is a group of rooms preceded by an antechamber, of which nothing is standing but a return at the east end of the wall or arcade. Three doors lead out of the antechamber into rooms 39, 40, and 41. In the central chamber (39) there is an arched niche at either end leaving a space 4·15 metres square which was covered by a dome set on squinches (Plate 68, Fig. 2). To east and west, the dome rested upon the arches of the doors leading into Nos. 40 and 41. Beyond 41 there is another room, 42, which was accessible from 41 only. On the north side of court I are two small rooms, 43 and 44, about 4·15 metres square and much ruined. Further west is the entrance to corridor 45. Court I is separated from court J by a wall which is ruined to its foundations. On the south side there is a single long chamber (47) with an antechamber; the north side is occupied by corridor 45, which is accessible from court J by a door in the north-west corner of the court. Corridor 45 communicates with corridor 17, a transverse arch separating the two. I call attention to the fact that the vault builders were always careful to avoid intersection; when two barrel vaults meet at right angles, the one is always divided from the other by a transverse arch. This is very noticeable in corridor 17, where the vault is standing. In the eastern arm of the corridor, opening out of court D, the east and west vault terminates against a transverse arch so as to allow the north and south vault of the western arm to run straight through to the head wall at the northern end.
