Mix some vermilion finely ground, with linseed-oil, but so liquid that it will run or flow in a pen, and with this trace the lines of a print; arid as soon as you have done all, with a spunge and water wet the back side of the print, and turn the printed side downwards upon a piece of white paper, so that it may lie smooth; then lay over that a piece of dry paper, and press it hard on every part, and the lower white paper will receive the im pression: but if you have a press, such as is used for pressing linnen, it will be better to put the paper between two of the wooden leaves, and then to screw the press as tight as may be, for then you will have a fine impression.
