"Heat was communicated to these flues by means of _Praefurnia_. In
the middle of the northern wall of the second stove, the ruins of one
of these furnaces appear. It consists of strong walls of about 16ft.
square, with an opening in the centre of about 3ft. wide, which
terminates conically in the north wall of the stove 2 ft. wide where
part of the broken arch bears evident marks of fire. About the mouth
of the furnace there were scattered pieces of burnt wood, charcoal,
&c., evident proofs of their use.

"On each side of the furnace, adjoining to the wall of the
northernmost stove, is a semi-circular chamber of about 10ft. 4in.
by 9ft. 6in. Their floors are nearly 2ft. 6in. lower than that of the
next stove into which they both open. The pavements are tesselated
with variegated rows of pebbles and red bricks. To the northward of
these there appear ruins of two other square chambers of more ordinary
work." Thus far Lucas.

Dr. Sutherland goes on to say, "Since the time of his (Lucas's)
publication the ground has been further cleared away. There now
appears another semi-circular bath to the southward, of the same
dimensions exactly with the first. What he calls the Great Bath, with
its semi-circular _Hypocausta Laconica_, &c., forms only one wing
of a spacious regular building. From a survey of these, our ruins,
we may, with some certainty, determine the nature of these _Balnea
pensilia_.... The Eastern Vapour Baths are now demolishing in order
to make way for more modern improvements. Whenever the rubbish that
covers the eastern wing of the Roman ruins comes to be removed similar
_Balnea pensilia_ will doubtless be found.
