e methods of lighting the bath. As a rule, much
artificial light will be required. The hot rooms, being often in a
basement, are as a rule but feebly illumined from areas and the like.
Seeing that purity of atmosphere in these apartments is of so vital
importance, the method of artificial lighting adopted should not be such
as impregnates the air with obnoxious and harmful, if unnoticeable,
fumes. Gas, for this reason, used in the ordinary manner, is
objectionable, as the ventilation being by means of low-level exits for
the foul air, the products of combustion must of necessity pass by and
envelop persons below the burners, though, of course, in a diluted
state. Should, therefore, gas-lighting be employed in a sudatory
chamber, it should for preference be on one of those systems whereby the
burner is cut off from the atmosphere of the room, and provision made
for carrying off the fumes. Happily, the use of electric lighting is at
last increasing with marked rapidity; and the incandescent light is
admirably adapted for all purposes of the Turkish bath. Where it can
possibly be adopted it is a great addition to a bath.

For cooling room purposes gas is not so objectionable, except that it is
heating, and assists in vitiating the atmosphere. But inasmuch as the
fumes in this case will ascend with the general body of air, the
objection to gas is much lessened in these apartments. Nevertheless, the
electric light is the illuminant to be coveted.

The quality of the lighting in the cooling room should be toned and
softened. It is not a place for brilliant general illumination, but
rather for a soft light pervading the whole, and auxiliary lights where
required, such as near couches, &c.--a system, in fact, diametrically
opposed to sun-burner illumination. Nothing more objectionable of its
kind can well be imagined than a glaring light in the ceiling of a
cooling room. It would be found intolerable.

For practical purposes, the greatest amount of light required in any
part of a frigidarium is that at the heads of the couches, where it must
be of such strength as will admit of comfortable reading. One
gas-burner, or one small incandescent lamp, to every two couches is a
fair allowance. If effect be desired, there is, of course, much in the
distribution of the illuminating agent that affects for good or evil,
and the placing and the relative powers of the lamps or burners must be
considered. The dominant point of light might
