e. The heating chamber is placed adjoining this. The principle
of its construction is that generally adopted in the baths erected under
the late Mr. Bartholomew's direction, viz. a furnace with a coil of thin
iron flue-pipes, radiating, in a measure, a certain amount of heat
directly into the hot rooms. The bath rooms are divided from one another
by glazed wood partitions, as distinct from the solid walls dividing
baths like the Hammam and Savoy. A consideration of these two methods of
dividing the hot rooms, does not, however, concern us here. A staircase
from the entrance vestibule leads to the ladies' baths on the second and
third floors, where also are manager's and other private rooms.

Broadly speaking, baths may be divided into two classes, viz. those in
which the various apartments are arranged _en suite_, and those
irregularly planned. Where possible the former arrangement is
preferable, as, with the hot rooms in a line, the circulation of air is
facilitated. Fig. 11 is a section of a set of hot rooms arranged _en
suite_; and the baths at Figs. 24 and 25, in Chapter VIII., are planned
on this principle.

As I have said above, where a basement and ground floor are available,
and a little space can be gained at the back of the existing building,
the office, cooling and dressing rooms can be arranged on the ground
floor, and the bath rooms proper on the basement level, but with light
and air above. If the site be an ordinary narrow-fronted town house,
and the bath an unassuming one, the plan may be arranged after the
manner of Mr. Joseph Burton's baths (Fig. 3), in the Euston Road,
London. Here a pair of ordinary town dwelling-houses are pressed into
the service of the bath. The basement and ground floors are devoted to
the baths, the upper floors forming a private hotel. On one side are the
gentlemen's, and on the other, the ladies' baths. Entering the former,
we find a space on the ground floor, fronting the street, serving as an
office. Adjoining this is a range of dressing-boxes, and further on a
cooling room, excellently lighted by a large window forming the whole
end of the apartment. From this little frigidarium a marble staircase
leads to the door of the tepidarium, formed at basement level at the
back of the houses. This chamber is lighted by means of a ceiling-light
constructed in the form of a small, flat dome, with stained-glass stars
set therein. A marble seat runs round the whole of this chamber. On
