hing cove, we have exposed our bodies to the
fiercest rays of the morning sun whilst yet we breathe the fresh, cool,
ozone-laden air.

Till modern invention, however, has provided us with this desideratum in
the heating of the bath, we must be satisfied with existing methods. And
unless something really practical is perfected, it is far wiser to rely
upon the system of heating by convection through the air--the principle,
generally adopted, of continuously passing large quantities of
freshly-heated air through the sudatory chambers; exposing, however, the
heating apparatus, so that a maximum of radiant heat may be obtained;
and carefully guarding against injuring the air whilst raising its
temperature. If only existing baths were in perfect harmony with this
principle, one would have little cause for complaint, and might the more
leisurely await the perfecting of the true radiating principle of
heating, which I am satisfied is the one upon which we must base all our
hopes for the future of the "Turkish" bath.

For practical purposes, it will suffice if the method of heating and
ventilating a bath on the hot-air principle be explained. This I shall
now do, and subsequently give plans and instructions for methods of
heating and ventilating on systems where, by the exposure of the heating
surfaces of furnaces, a large proportion of radiant heat is thrown into
the hot-rooms.

The necessary appliances, and arrangements for the heating and
ventilation of a bath on the ordinary hot-air principle comprise a
furnace in its chamber, with flues or shafts supplying cold, and drawing
off the heated air, and a stokery with provisions for firing and storing
coke, &c. Too often the stokery is unscrupulously cramped, and the life
of the stoker thereby rendered anything but pleasant. Its design is a
simple matter, and perhaps for this reason neglected. The arrangement
and construction of the furnace chamber requires care, and the selection
of a stove or furnace great judgment. As regards the latter feature, the
most important point to consider is the nature of the heating or
radiating surfaces. What will raise the air to the required temperature,
without in the process depriving it in any way of its vitalising
elements, and without adulterating it with either smoke and fumes from
leakage, or with particles of foreign matter given off from the material
employed in its construction?

There is nothing really better as a radiating surfac
