The hair is most definitely UP, and gone are the usual greys and whites and in its place a shocking aqua-marine teal.

A tint of aqua-marina of marvellous delicacy spread a soft hue throughout the cavern.

Neither this acid nor the nitrous will dissolve gold or platina; but a mixture of them, called aqua regia, will do it.

Platina is precipitated from a solution in aqua regia by sal-ammoniac, as gold is by martial vitriol.

It is soluble in the vitriolic or marine acids, and reduced to a yellow calx by nitrous acid or aqua regia.

If a little aqua-fortis be mixed with the water, the writing will dry well, and not run out of its form when the paper is wetted.
