3795. Ink.—To make five gallons of good ink, costing but twelve-and-a-half cents, take half a pound of extract of logwood, and dissolve it in five gallons of hot water, and add half an ounce of bichromate potash. Strain and bottle it.
3796. Blue Tracing Ink.—Indigo tied in a flannel bag, moistened with water. Put a lump of white sugar into an egg-cup, and squeeze out the blue on it; the sugar stiffens it, so as to prevent its running, and the color depends on the quantity of water used. Use a quill pen.
3797. Marking Linen, preparation.—The preparation used for wetting linen, previous to marking it with ink, is a drachm of salt of tartar in one and a half ounces of water.
3798. Economy in Candles.—If you would burn a candle all night, unless you use the following precaution, it is ten to one an ordinary candle will gutter away in an hour or two, sometimes to the endangering the safety of a house. This may be avoided by placing as much common salt, finely powdered, as will reach from the tallow to the bottom of the black part of the wick of a partly-burnt candle, when, if the same be lit, it will burn very slowly, yielding sufficient light for a bed-chamber; the salt will gradually sink as the tallow is consumed, the melted tallow being drawn through the salt, and consumed in the wick.
3799. Deafness.—Take three drops of a sheep's gall, warm, and drop it into the ear on going to bed. The ear must be thoroughly syringed with warm soap and water in the morning.
