th, where the whole of the foul air is drawn into one
vertical shaft of sufficiently wide section. Much that I have said on
the heating and ventilation, and, indeed, on many matters in connection
with the design of public baths, applies in the case of the private one,
and the reader is therefore referred to preceding pages for many hints
as to its construction.

In the accompanying figures I have endeavoured to explain the
arrangement and construction of private baths, from those formed by
converting existing rooms into bath rooms, to an elaborate and complete
design. Fig. 22 (A) is a plan of Mr. Urquhart's cheap private bath, an
apartment only measuring 11 ft. by 16 ft., yet forming an effective
sudatory chamber, with simple iron stove, couch, seat, and sunk tank or
lavatrina. On this principle I have arranged the plans of the baths
adapted to existing rooms in a house, shown at Fig. 23. One plan shows a
hot room built on to an existing ordinary bath room. A doorway is formed
in the old external wall, and the new chamber constructed with hollow
walls, with glazed bricks internally. An extra room would, of course, be
thus formed on the floor below. A fireproof floor would be provided, and
the pipes from iron stove conducted to old fireplace in bath room, which
would become the lavatorium, and undressing room if necessary. A
double-doored lobby is formed in the latter apartment, and the slipper
bath used as ordinarily. It will be seen that by appropriating the
adjoining bed room, a frigidarium is obtained, by taking away the
flue-pipe to a new chimney, and knocking a doorway through the old
partition wall, thus making a complete set of bath rooms.

The other plan, given at Fig. 23, shows an existing room divided into a
combined hot room and washing room, and a cooling room. Three of the
walls being ordinary external walls, the hot room is lined with lath and
plaster on quartering, leaving an air-space between to prevent loss of
heat by absorption and radiation. One or two of the spaces between the
quarters should be formed into lath and plaster flues, for the
withdrawal of the vitiated air, being connected below with the hot room,
and above lead into the open air. A pugged partition and double-doored
lobby separate the rooms. Space is left in the hot room for a
full-length couch opposite the radiating stove, which has a metal screen
