Blacking For Harness.
II.—Best glue, 4 ounces; good vinegar, 1 1/2 pints; best gum arabic, 2 ounces; good black ink, 1/2 pint; best isinglass, 2 drachms. Dissolve the gum in the ink, and melt the isinglass in another vessel in as much hot water as will cover it. Having first steeped the glue in the vinegar until soft, dissolve it completely by the aid of heat, stirring to prevent burning. The heat should not exceed 180° F. Add the gum and ink, and allow the mixture to rise again to the same temperature. Lastly mix the solution in isinglass, and remove from fire. When {451} used, a small portion must be heated until fluid, and then applied with a sponge and allowed to dry on.
