![tificil spirit. Ink stains by oxalic acid or superoxalate of potasb. Iron moulds by the same; but, if obstinate, it lias been recommended to moisten them with ink, then remove them in the usual way. See page 428. Grease Spots. See Scouring Drops. Red Spots on black cloth, from acids, are removed by spirits of hartshorn, or other solutions of ammonia. Stains of Marking Ink or Nitrate of Silver, to remove. 1. Wet the stain with fresh solution of chloride of lime, and after 10 or 15 minutes, if the marks have become white, dip the part in solution of ammonia or of hyposulphite of soda. In a few minutes wash with clean water. 2. Stretch the strained linen over a basin of hot water, wet the mark with tincture of iodine. 3. They may also be removed by cyanide of potassium; but this should be done by the druggist, and not intrusted to any one else. Starch. Starch is procured from various roots and seeds. Its varieties are numerous; but a few of the most im- portant only can be noticed here. Arrowroot (West Indian). The fecula of the tubers of the Maranta arundinacea. The fresh tubers are washed and beaten to a pulp, which is well stirred in a large tub of cold clean water, and the fibrous part wrung out by the hands, and thrown away. The water in which the fecula is suspended is passed through a hair sieve or coarse cloth, allowed to settle, and the water poured off. After being repeatedly washed, the wet starch is drained, and after- wards dried in the sun. [The other varieties of arrow- root (see page 272) are prepared by analogous processes from the roots which yield them.] Potato Starch. The tubers are washed and peeled, usually by machinery, rasped by a revolving grater, and the pulp washed on hair sieves till freed from the starchy matter. Successive portions of the pulp are thus treated till the vessel over which the sieves are placed is suffi- ciently full. The starch held in suspension in water sub- sides to the bottom; the water is then drawn off, and the starch stirred up with fresh water, and again allowed to subside. This is repeated several times till the starch is sufficiently pure. The fibres and the washing waters](https://iiif.wellcomecollection.org/image/b28091048_0448.jp2/full/800%2C/0/default.jpg)
