Copying Ink to be Used Without Press or Water.

Well mix three pints of jet-black writing ink and one pint of glycerine. This, if used on glazed paper, will not dry for hours, and will yield one or two fair, neat, dry copies, by simple pressure of the hand, in any good letter copy-book. The writing should not be excessively fine, nor the strokes uneven or heavy. To prevent “setting off,” the leaves after copying should be removed by blotting-paper. The copies and the originals are neater than where water is used.
