Supplying Imperfections in Old Books
It often occurs that a valuable and rare work has a leaf torn or missing. In order to supply it, the first step will be to obtain the use of a perfect copy as a model. Then procure paper of the same colour as the leaf to be mended, and cut it carefully to correspond with the torn portion. After the piece has been neatly adjusted, tip it and the leaf, very lightly, along the edges with paste made of rice-flour; then place a piece of tissue-paper on both sides of the leaf, and smooth it carefully with the folder; then close the volume and allow it to remain until perfectly dry. Then proceed to remove the tissue-paper, and it will be found that the portions that adhere where the joining occurs will be strong enough to secure the piece to the leaf of the book. The letters may be then copied from the perfect copy and traced upon the inserted piece. The general appearance will depend upon the skill displayed in order to produce a successful imitation of the original.
