and is provided invariably with a posterior court. In one case only, court H, a shallow lîwân group is placed at the west end of the posterior court. All the latitudinal chambers (19, 28, 32, and 42) behind the lîwâns are completely ruined. I conjecture that they were vaulted, but it is possible that they were not wholly covered, like the corresponding chambers behind the lîwâns at Ukhaiḍir. On the analogy of Ukhaiḍir they must have served the purpose of kitchens. I saw no trace in court C of the columns which are placed there in the French plan. At the east end there is a shallow lîwân group (21, 22, and 23), the lîwân being 4 metres deep. To the north of this group lies a short passage leading to a door which communicates with the open platform. A corresponding passage (20), 2·30 metres wide, leads out of the north-west corner of court C, runs along the north side of courts D, E, and F, drops on to the lower level in the same manner as corridors 11 and 12, is continued as far west as they, and then turns off at right angles and joins the cross-passage which connects them. North of court C are two chambers on the upper level (106 and 24). No. 106 is a long passage room with two rectangular arched niches in the south wall, a door at the east end opening on to the platform, and a door at the west end which gives access to a ramp that descends into the exterior park, between the retaining wall to the south and the wall of a chamber on the lower level to the north. In the north wall of No. 106 there is a door leading into No. 24, a much ruined room about 7·50 metres square, and a door further west opening on to the roof of a short passage. Courts E and F stand in the same relation to one another as courts C and D; court E is the forecourt of a lîwân group with a kitchen (25 to 28); court F is the posterior court. The western wall of court F is the retaining wall of the mound on which the rooms and courts of the upper level are built. Court F, together with No. 28, are omitted in M. de Morgan’s plan, a fact which shows that there must be serious errors in his measurements.
