IX. COLOR BOX.--These are generally found on sale at the shops,
and usually contain eight colors, four brushes and a gold cup.
The artist would, however, do well to obtain, all the colors mentioned
in the last chapter of this work, and be sure to get the very best,
as there are various qualities of the same color, particularly carmine,
which is very expensive, and the cupidity of some may induce them
to sell a poor article for the sake of larger profits.

STILL.--Daguerreotypists should always use distilled water for solutions,
and washing the plate, as common water holds various substances in solution
which detract very materially from the excellence of a photograph,
and often gives much trouble, quite unaccountable to many.
For the purpose of distilling water the apparatus represented at Fig. 16
is both convenient and economical.

It may be either wholly of good stout tin, or of sheet iron tinned
on the inside, and may be used over a common fire, or on a stove.
A is the body, which may be made to hold from one to four gallons of water,
which is introduced at the opening b, which is then stopped by a cork.
The tube d connects the neck a of the still with the worm tub,
or refrigerator B, at e, which is kept filled with cold water by means
of the funnel c, and drawn off as fast as it becomes warm by the cock f.
The distilled water is condensed in the worm--and passes off at the cock b,
under which a bottle, or other vessel, should be placed to receive it.
The different joints are rendered tight by lute, or in its absence,
some stiff paste spread upon a piece of linen and wrapped around them
will answer very well; an addition of sealing wax over all will make
them doubly secure.
