Fish glue holds the first rank among the substances of this kind on account of its being colourless., ,The addition of the brandy contributes towards its longer preservation, and accelerates its dessication when employed, but it lessens the limpidity of the liquid. This consistence would prevent it from being freely extended over the works which are to be sized, were it not diluted at the time of its being employed with a little warm water. It is in the latter state of liquidity that it is applied to articles which can stand the required degree of heat, such as wood, fans, &c. But when it is apprehended that this temperature may produce bad effects on the colours or on the cut paper figures, for cementing which it may be employed, it is then diluted with cold water and it is kept liquid at the temperature of the atmosphere., ,
