Boil a small piece of gum benzoin in some spirits of wine till it is dissolved, (five minutes boiling will be sufficient,) then bottle for use.  A few drops of this in a glass of soft water (sufficient to make the water a milky colour) makes a delicious wash; apply with a towel or linen cloth.  This article will make the skin as soft as velvet, and will constantly preserve rosy cheeks and lips, and for this it has not equal in the world; besides, it is as harmless as a sun-shower.  As it is not a paint, it will not act just on the moment when applied.

Take of tincture of elder blossoms 1/2 oz., best beef marrow 1 teaspoonful, orange flower water 1/2 pint, cassia buds 1 oz., blanched bitter almonds 2 oz., spirits of oriental roses 4 drms.; mix all, and when the solution acquires the colour and consistency of milk it is fit for use.  This article is for beautifying the complexion, making the skin as soft, as fair, and as rosy as that of a healthy infant; apply at pleasure.  It is not only harmless, but will prove a speedy cure for all pimples, blotches, &c.

529.  Instruction for gilding

Dissolve a gold dollar in nitro-muriatic acid,—­(2 ozs. muriatic to 1 of nitric,) then dissolve a 1/4 lb. of copperas in a pint of hot water, and pour it into the dish containing the gold and acid, pouring in a little at a time, till it stops boiling or foaming up; then let it stand and settle about six hours; then strain off the copperas-water carefully, and the gold will appear like a brown or dark yellow powder in the bottom of the dish.  You will then proceed to wash the gold, which is done by pouring hot water on it; let it stand and settle a few minutes, and then drain off.  Continue washing in this manner till there is no acid or copperas taste; then add to the gold in the bottom of the dish from 1-1/2 to 2 oz. cyanuret potassa, dissolved in about 1/2 pint pure soft water.  The solution is then ready for use.  Gild by laying a piece of pure zinc in contact with the article to be gilded, in the solution.

530.  Directions for silvering

Dissolve a silver dollar in about 2 ozs. of nitric acid by heating; then dissolve a tablespoonful of salt in about a quart of water; pour it into the dish with the silver and acid; let it stand and settle a few minutes, and the silver will settle to the bottom in a white powder.  Then drain off the water carefully, and add more water, then drain off again.  Continue washing in this manner till no acid or salt taste remains; then add a quart or more of pure soft water, and cyanuret potassa enough to take it up, or nearly so.  The solution is then nearly ready for use.

Silver by laying a piece of zinc in contact with the article, the same as in gilding.  If the article you are silvering or gilding corrodes or turns black, it wants a little more cyanuret.  In gilding or silvering, the article must be thoroughly cleaned, and great care must be taken that the water used is of the purest kind.
