Dissolve steel in a rectified spirit of salt, so shall you have a green and sweet solution which smells like brimstone. Filter it and abstract all the moisture in sand with a gentle heat. There will distill over a liquor as sweet as rain water. Steel, by reason of its dryness, detains the corrosiveness of the spirit of salt which remains in the bottom like a blood red mass which is as hot on the tongue as fire. Dissolve this red mass in oil of flints or of sand, and you shall see it grow up in two or three hours like a tree with stem and branches. Prove this tree at the test, and it shall yield good gold which this tree has drawn from the aforesaid oil of sand or flints which has a golden sulphur in it.
