A new touch-stone for gold and silver wares : directing all buyers of large plate, or small works (as silver or goldhilts, buckles, watch-cases, pins and studs in watch-cases, money-boxes, tobacco-boxes, bells and sockets for corals, buttons and tags for garments, chirurgeons-instruments, rings, chains, lockets, or other goldsmith works), how to know whether they buy or wear such as are of the lawful standard-allay, or adulterated and unlawful, and how to recover recompence against the offenders : and also discovering the principal matters of the goldsmiths and cutlers (and material things of all other manual) trades.
