History of copying

In the common ink used, dissolve lump sugar (1 dr. to 1 oz. of ink). Moisten the copying paper, and then put it in soft cap-paper to absorb the superfluous moisture. Put the moistened paper on the writing, place both between some soft paper, and either put the whole in the folds of a carpet, or roll upon a ruler 3 or 4 times.

_To Copy Writings._

Take a piece of unsized paper exactly of the size of the paper to be copied; moisten it with water, or with the following liquid: Take of distilled vinegar, 2 lbs.; dissolve it in 1 oz. of boracic acid; then take 4 oz. of oyster-shells calcined to whiteness, and carefully freed from their brown crust; put them into the vinegar, shake the mixture frequently for 24 hours, then let it stand till it deposits its sediment; filter the clear part through unsized paper into a glass vessel; then add 2 oz. of the best Aleppo galls bruised, and place the liquor in a warm place; shake it frequently for 24 hours, then filter the liquor again through unsized paper, and add to it after filtration, 1 qt., ale measure, of pure water. It must then stand 24 hours, and be filtered again, if it shows a disposition to deposit any sediment, which it generally does. When paper has been wet with this liquid, put it between 2 thick unsized papers to absorb the superfluous moisture; then lay it over the writing to be copied, and put a piece of clean writing-paper above it. Put the whole on the board of a rolling-press, and press them through the rolls, as is done in printing copperplates, and a copy of the writing will appear on both sides of the thin moistened paper, on one side in a reversed order and direction, but on the other side in the natural order and direction of the lines.
