dispensed with altogether.

For hydropathic purposes the lavatorium is generally required to have
rather more elaborate water-fittings than other baths. The needle bath
should include the ascending shower, the back shower, and the spinal
douche--a small nozzle behind the rose of the vertical shower. The
regulating appliances for these various showers, sprays, &c., should be
brought together, and conveniently placed for the attendant. A very
ingenious appliance, suitable for a hydropathic bath, is a thermometer
regulating valve, which indicates the temperature of the water being
supplied to the bather. The waters mix in a ball, into which is inserted
the bulb of a sensitive thermometer, which rises and falls as the hot or
cold handles are turned.

If the shampooing and washing room of the Turkish bath is to be used for
the administration of the tonic water baths to other bathers besides
those taking the Turkish bath, it must be made of ample dimensions. So,
also, if the cooling room is to be used as a reposing room for other
bathers, it must be made of large size.

Perfect ventilation is of paramount importance in baths used for the
treatment of disease. Purity of atmosphere in the hot rooms is a vital
necessity, and so also is it in the miscellaneous bath rooms of a
hydropathic establishment.

Unreadiness is a great vice in the Turkish bath appended to these
institutions. Hot rooms beneath their proper temperature, and lukewarm
water, are unpardonable delinquencies, either in the early morning, in
the evening, or during the day. For this reason I would recommend a
furnace of fireclay, as it retains its heat for a long time, and is not
subject to the rapid changes of iron stoves.

Much of that which I have said with respect to the hydropathic bath will
apply to the design of the bath for hospital and asylum purposes. Here,
however, efficiency is all that is required, and everything need be but
of the plainest description. The conditions and exigencies of each case
must determine the size, position, and nature of the suite of bath
rooms. All that has been said upon the subject of the design and
construction of the bath must be studied, and the principles, herein
given, applied to the peculiar circumstances. So also in regard to
Turkish baths for hotels, and for residential blocks of buildings, and
for clubs.

There is a wide field for activity in Turkish bath building, in the
increased provision of baths in hospita
