Sometimes the gold wears off in patches from gilded silver and other chains, and it is desirable to remove the rest of the gold, though regilding the chain is generally preferable. To remove the gold, proceed thus: In a basin put a tablespoonful of nitric acid and three table-spoousful of muriatic acid with an equal quantity of water, and make the whole warm. Carefully swill the chain in this, and well rinse in clean water until all the gold lias been removed; then dry the chain and polish it.
