The Silver Tree
Dissolve an ounce of fine silver in three ounces of strong aqua
fortis, in a glass bottle. When the silver is dissolved; pour the aqua
fortis into another glass vessel, (a decanter will be best,) with
seven or eight ounces of mercury, to which add a quart of common
water; to the whole add your dissolved silver, and let it remain
untouched.
In a few days the mercury will appear covered with a number of little
branches of a silver colour. This appearance will increase for a month
or two, and will remain after the mercury is entirely dissolved.
