GREASE. Grease spots, especially when very recent, can sometimes be drawn out by an absorbent powder such as impalpable clay or chalk. The spotted leaf is enclosed between two tins or boards, both sides of the spot well dusted with the powder, and the book closed tightly and set aside for several hours. Some kinds of grease absorb more slowly than others. If this operation is unsuccessful, alcohol, ether or benzine may be tried.

(*) A weak solution of pure or caustic potash operates very rapidly. If the ink on the page or I print is turned gray by this, it may be restored by a wash l of acid in very weak solution.

(*) Applied with a brush, first around the outside of the spot, then in narrowing circles until the centre is reached. Blotting paper is then placed on both sides of the sheet, over the spot, and a hot flat-iron applied. The absorbent powder ("French Chalk" answers very well) will operate better if the powdered sheet is enclosed simply between two pieces of paper, and a hot flat-iron applied. Plenty of powder should be used. M. S. B.

WHITE OF YELLOW WAX. These spots yield promptly to pure turpentine, especially in a warm bath. When the spots thicken, they are lifted off with a scraper, or blotting paper may be applied, pressed down with a heated iron.

STEARINE. Wax tapers are today replaced by a kind of liquid grease, stearine, spots of which give paper a disagreeable transparency. These dissolve in warm alcohol or boiling water, built the spot remains stiff and the brilliance of the ink is reduced. The greater part of the stearine spot may be removed by the same process indicated for wax.

SEALING WAX. RESIN AND RESINOUS VARNISH. All dry resins yield to a warm alcohol bath. The thick part is removed as above. Sealing wax colored red, blue, etc., leaves a corresponding tint which is very tenacious.

TAR, PITCH, etc. These spots are rarely encountered. They give way to warm turpentine or cold benzine. If a dark trace remains, it sometimes may be removed by oxalic acid if the spot has not been burned by the hot tar. Whenever turpentine is used on any spots, it should always be the purest obtainable.

EGG YELLOW. This is always mixed with a little albumen, a matter which thickens in boiling water and can be drawn from the paper, along with the yellow. If the paper is smooth and well sized, all will disappear under a sponge in a bath of hot water. There sometimes remains a yellowish trace. To remove this, apply with a brush chlorated lime and then very weak hydrochloric acid.

MUD. This may be removed simply with a wet sponge or in a warm water bath. Where the paper is rough and absorbent, soap jelly should be used. If a dark trace remains, it usually will yield to oxalic acid or cream of tartar.
