CHAPTER X. 
OF THE ARRANGEMENT AND PARTS OF BATHS. 
FIRST, as warm a spot as possible is to be selected, that 
is to say, one sheltered from the north and north-east. The 
hot and tepid baths are to receive theirlight from the winter 
west ; but, if the nature of the place prevent that, at all 
events from the south, because the hours of bathing are 
principally from noon to evening. Care must be taken 
that the warm baths of the women and men adjoin, and 
have the same aspect; in which case the same furnace and 
vessels will serve both. The caldrons over the furnaces 
are to be three in number, one for hot water, another 
for tepid water, and a third for cold water : and they 
must be so arranged, that the hot water which runs out 
of the heated vessel, may be replaced by an equal quantity 
from the tepid vessel, which in like manner is supplied 
from the cold vessel, and that the arched cavities in which 
they stand may be heated by one fire. The floors of the 
hot baths are to be made as follows. First, the bottom is 
paved with tiles of a foot and a half inclining towards 
the furnace, so that if a ball be thrown into it, it will not 
remain therein, but roll back to the mouth of the furnace; 
thus the flame will better spread under the floor. Upon 
this, piers of eight inch bricks are raised, at such a dis¬ 
tance from each other, that tiles of two feet may form 
their covering. The piers are to be two feet in height, 
and are to be laid in clay mixed with hair, on which the 
above-mentioned two feet tiles are placed, which carry
