163. TRUE IMITATION OF GOLD

Dr. Harmsteadt's imitation of gold, which is stated not only to
resemble gold in colour, but also in specific gravity and ductility,
consists of 16 parts of platinum, 7 parts of copper, and 1 of zinc,
put in a crucible, covered with charcoal powder, and melted into a
mass.


164. TRUE IMITATION OF SILVER

Imitation of pure silver, so perfect in its resemblance that no
chemist living can tell it from pure virgin silver. It was obtained
from a German chemist now dead; he used it for unlawful purposes to
the amount of thousands, and yet the metal is so perfect that he was
never discovered. It is all melted together in a crucible, here it
is: 1/4 oz. of copper, 2 oz. of brass, 3 oz. of pure silver, 1 oz.
