This powder, which is erroneously called salt of lemon, is in reality composed simply of equal portions of finely pulverized salt of sorrel and cream of tartar, (for instance an ounce of each,) mixed together in a mortar, and afterwards put into small covered boxes, or gallipots. It will immediately remove ink spots, fruit stains, etc, from the hands or from any articles of white linen or muslin; first wetting the place with water (warm water is best) and then with your finger rubbing on the powder, till the stain disappears. Immediately afterwards wash it off with soap-suds. If applied to a coloured article that has been inked or stained, the powder in removing the stain will take out the colour. But the colour (particularly if black) may in most cases be restored by rubbing the place with hartshorn; which if very strong should be somewhat diluted with water, or it will leave a tinge of its own. If the hartshorn fails to restore the colour, it is on account of some peculiarity in the dye. It is always worth trying. We have seen a large splash of ink taken out of a carpet by first wetting it with warm water and rubbing on some of the above-mentioned stain powder. The colours were all restored to their former brightness by afterwards applying hartshorn. Next day, the place where the ink had been spilled on the carpet could not be distiniruisned. We have also known the same ex-periment tried with perfect success on a mousseline de laine dress on which an ink-stand had been overset.

Ink spots can be removed from while clothes by the simple application of a bit of clean tallow picked from the bottom of a mould candle, rubbed on the ink spot, and left sticking there when the article goes into the wash-tub. It will come out of the wash freed from the ink stain.

This stain powder should be kept out of the way of children, as if swallowed it is poisonous.

Fresh lemon-juice mixed with a little salt is excellent for removing stains of ink, iron mould, etc.
