with the valve
shown at Fig. 13, about 18 in. above the basin, the outlet of the valve
being fitted with a foot or 15 in. of indiarubber hose. In the latter
case the pipes and valve would stand some 9 in. from the wall, and
depend from the horizontal supply pipes, which in their turn could be
carried on wrought-iron brackets affixed to the wall, or be hung by iron
ties, as indicated by dotted lines at Fig. 16. The _internal_
diameter--the measurement given in all the figures--of these branch
pipes to taps over shampooing basins should be 3/4 in.

A Shampooing Basin.]

Cocks and valves for the purposes of the Turkish bath are best of the
"gland" pattern. They should have bold handles. Those of the screw-down
type are useless, except as stop-cocks. Roundways should be used, and,
to insure freedom of running, the turning part should be equal to the
inner diameter of the pipes. The whole should be of gunmetal, and, if
the pipes to be used be of iron, screwed at the end. Fig. 13 shows the
type of valve to be employed to regulate the temperature of water for
shower baths, &c. To be useful, as well as bold and effective in
appearance, the handles should be large.

Valve for Regulating Temperature of Water.]

_In every case_, the cold water must be placed on the right hand, and
the hot on the left.

The earthenware basin is provided to hold water mixed to the required
temperature. A waste and overflow are not shown in the illustration, but
they should be provided. The basin is best wide and shallow--shallower
than shown. There should be no overhanging ledge to catch the
shampooer's hand-basin; for this reason I have shown, at Fig. 12, the
basin sunk into the marble slab, instead of the marble being on top, as
ordinary. The copper hand-basin is provided for the shampooer to take
water from the earthenware basin and throw over the shampooing slab, or
over the bather. In addition, a wooden, copper-banded soap-bowl must be
provided.

Should there be a row of shampooing basins and benches, the horizontal
supply-pipes must be continued along the wall, and branches dropped to
each basin. The basins are most conveniently placed when raised somewhat
higher than the benches. In the illustration given, I have shown how to
arrange horizontal foul-air flues under the basins. In other cases the
fixing of the basins will be much simpler. For pure lavatorium purposes
these basins, c
