(a) The surface of the parchment must first be moistened with. alcohol or brandy and pressed while still moist upon glue or paste. When two pieces of parchment are to be joined, both must be moistened in this way. It is said that the paper will sooner tear than separate where it has been thus fastened together.
(b) Another way is to put a thin piece of paper between the surfaces of parchment, and apply the paste.' This forms a firm joint, and can with difficulty be separated. Glue and flour paste are best adapted for uniting surfaces of parchment.
