There are now fairly laid open, the foundations and remains of very august Roman baths and sudatories, constructed upon their elegant plans, with floors suspended upon square-brick pillars, and surrounded with tubulated bricks, for the equal conveyance of heat and vapour.

"To the northward, separated by a wall of 3ft. 11in., stood the other Hypocaustum, with a door of communication. The floor of this is about 18in. higher than the other. These two rooms are set round with square-brick tubes of different lengths, from 16in. to 20in. in length and 6¾in. wide. These flues have two lateral openings of about 2in. square, 5in. asunder.
