To Remove Ink Spots.
First moisten the blots with a strong solution of oxalic acid, then with a clear saturated aqueous solution of fresh chloride of lime—bleaching powder. Absorb excess of the liquids from the paper as quickly as possible with a clean piece of blotting paper. Repeat the treatment if necessary, and dry thoroughly between blotting pads under pressure.
Electro Gilding in Colors.
Electro-gilding in various colors may be readily effected by adding to the gold bath small quantities of copper or silver solution until the desired tint is obtained. A little silver solution added to the gilding bath causes the deposit to assume a pale yellow tint. By increasing the dose of silver solution a pale greenish tint is obtained. Copper solution added to the gold bath yields a warm, red gold tint. It is best to use a current of rather high tension, such as that of the Bunsen battery, for depositing the alloy of gold and copper.
To Remove Oil Marks From Paper.
Oil marks on wall paper, where careless persons have rested their heads, may be removed by making a paste of cold water and pipe clay or fuller’s earth, and laying it on the stains without rubbing it in; leave it on all night, and in the morning it can be brushed off, and the spot, unless it be a very old one, will have disappeared. If old, renew the application.

Solid Pocket Glue.
Is made from 600 grams of glue and 250 grams of sugar. The glue is at first completely dissolved by boiling with water; the sugar is then introduced into the hot solution, and the mixture evaporated until it becomes solid on cooling. The hard mass dissolves very rapidly in lukewarm water, and then gives a paste which is especially adapted for paper.
