Thus, for instance, a liquid which 1956. To Prepare Lithographic Pa- has given the most satisfactory results is obper. Lay on the paper 3 successive coats of tained by adding to a solution of 3 ounces white sugar candy and 2 ounces white shellac, in about 2 pints spirits of wine, a decoction of about 1 ounce fucus crispus (Irish moss) in 1 pint distilled water. sheep-foot jelly, 1 layer of cold white starch, and 1 layer of gamboge. The first layer is applied with a sponge dipped in a hot solution of the jelly, thinly, but very evenly, over the whole surface; the next 2 coats are laid on in succession, each previous coat being first allowed to dry. The layer of starch, and then the coat of gamboge, are each applied with a sponge in the same way as the jelly. When parts isinglass, or gum-arabic, in 12 parts the paper is dry it must be smoothed by pass- water, using a varnisher's flow brush, and ing it through the lithographic press; the smoother it becomes, the better. The transfer of traces from the gamboge surface of paper thus prepared is perfect.

The gamboge must be dissolved the same day it is used, as it becomes oily by standing.

The starch should be a day old, and the skin removed from its surface. 1960. Το Fix Pencil or Chalk Drawings. Lay the drawing on its face, stretch it tightly on a board with drawing pins, and give the back 2 or 3 coats of a solution of 5 allowing each coat to dry before laying on the next. When dry, turn the drawing over, face upwards, and give it 1 or 2 coats in the same manner. This will usually be sufficient to fix the drawing, but the addition of 1 or 2 coats of a solution of 4 parts Canada balsam, in 5 parts turpentine, will afford still further protection.
