oast, and to cast it in
when the _Mason's_ Work was sufficiently dry, which only required two
Months time. That they might the better throw these Moles into the Sea,
they built them half upon the Sea-Coast, and half upon an heap of Sand
which they made close to the Sea-Coast; to the end, that this Sand which
was stopped by nothing but by the Walls, built only to support it during
the time that the Mole was a drying, might let it fall when the Sea came
to carry away the Sand after that the Walls were beaten down.

The _Bathes_ of the Ancients consisted of many Chambers; some for Men,
and some for Women.

Some of the Chambers had a moderate Heat, to warm their Bodies
insensibly, and prepare them for a stronger Heat to make them Sweat.

The Chamber they were to Sweat in, was called _Laconicum_, and was
round, and Vaulted like the ends of an Oven, pierced at the top with a
round Opening, which was opened and shut with a Buckler of Brass, which
hung at a Chain, by which means they augmented or diminished the Heat
according to the Proportion that they pull'd up, or let down the
Buckler.

One and the same Furnace heated both the Air and the Water, according to
the Disposition of the places which were nearer or further from the
Furnace, whose heat was communicated to the Chambers from under the
Flooring, which was made full of little holes.

The Water was likewise diversly tempered by the different situation of
three great Vessels of Brass, whose Water went from one into another,
and there were Pipes that conveyed these three sorts of Water into the
_Bath_.

The _Academies_ of the Ancients, which they called _Palaestra_, was a
place where the Youth learned Letters and their Exercises. They were
composed of three parts, _viz._ Of a _Peristyle_, a _Xyste_, and a
_Stadium_; the _Peristyle_ was a Court surrounded with _Portico's_,
which were of two sorts; three of them were Simple, and one Double.

The Simple stood in a row against three Bodies of Lodgings, composed of
many great Halls, where the Philosophers had their Disputes and
Conferences.

The Bodies of the Lodgings, which was the length of the double
_Portico_, and one part of the Bodies of Lodgings which turned in, were
distributed into several parts, for the Studies and Exercises of Youth;
for there they had their _Classes_, their _Baths_, their _Stoves_, and
their _Tenis-Court_.

The _Xyste_ was a place planted with Trees, and
