(From the American Lithographer and Printer.)

Map-Engravers' Wax.—Half an ounce gum benzoin, half an ounce of white wax, four ounces linseed oil. Boil down one-third.

Silver Ink.—White gum arabic, one part; distilled water, four parts; silicate of soda in solution, one part. Triturate with the best silver bronze powder, enough to give required brilliancy.

Cement for Iron.—Thoroughly mix and wet with sulphuric acid six parts of sulphur, six of white lead, one of borax. This makes a reliable cement for connecting iron.

To Render Fabrics Non-inflammable.—Soak them in a solution of 4 parts borax and 3 parts of epsom salts or sulphate of magnesia, shaken or well-mixed together, and immediately dissolved in from 20 to 30 parts of warm water. Thoroughly soak fabrics, wring out and dry in the open air.
