as the one first discovered. It was lined inside with fine stucco or plaster, 112 in. thick, and outside this were 2 inches of mortar. It rested on large tiles like those before mentioned, supported by pillars of smaller tiles similar to those before described, but not at such regular intervals.

Many of these are entire, and remain in situ. On the south side a leaden pipe, quite perfect, passes from the bottom of this cistern through the outer wall. This pipe probably conducted the hot water to the bath at the east end of the calidarium. The boiler had its stucco lining more perfect than the bath at the south-east end of the hypocaust.
