ocks, &c., are all the water-fittings to be considered;
but in an apartment combining the purposes of douche room--and perhaps a
plunge bath chamber--as well as a washing and massage room, more or less
of the fittings about to be described will have to be accommodated.

The tonic appliances for treating the bather subsequently to the
shampooing, the soaping, and the cleansing, are various. The most useful
is the simple shower bath, with a very large rose, and amply supplied
with water through a regulating valve. It is employed for thoroughly
cleansing the bather before he enters the plunge, whose waters are for
the common use of all. In many small baths its place is efficiently
taken by an ordinary hand rose or spray of the kind shown at Fig. 15.
The shower proper is usually fixed above the "needle" bath, as at Fig.
14, or formed by a continuation of the "backbone" of the needle. It is
best to have separate regulating valves for the needle and shower, as at
Fig. 16; but at Fig. 14 it is shown with a branch from the pipe
conducting to the needle, and with stop cocks. The needle-bath is a
skeleton-like structure having a large hollow backbone and branching
ribs. The water ascends the backbone, and, passing into the ribs,
squirts out of small holes punctured in their internal circumferences.
The bather stands in the centre of the apparatus, with the ribs
encircling him. The ribs should be of 1/2-in. copper piping, the
backbone and lesser supports being of iron, 2-1/2 and 1-1/2 in. diameter
respectively. In a convenient position for the attendant must be placed
the regulating valve.

A more elaborate contrivance may be made, which will include needle,
shower, ascending shower, spinal douche, and back shower; but this
should be left for hydropathic institutions and invalids. Simplicity in
these matters should be the great desideratum. The above-named
additions, however, may be briefly described. At Fig. 14 I have
indicated the position of ascending shower. It would be connected with
the pipe supplying needle and shower, and have a stop-cock. The spinal
douche is a little nozzle behind the shower proper, and should have
similar connection with the supply-pipe. The back shower or spinal
spray would be a rose placed about half-way up the iron backbone, and be
connected in the same manner. Avoid these complications in a bath for
healthy persons.
