First, melt the Gold, Silver, or Lead &c so that it may but just flow; then heat the Mercury till it begins to fume; and by little and little, pour the Mercury to the melted Metal, and stir them about with a warm Iron Rod, till they are incorporated. If you make the Amalgama so hard as to beat into a Powder, you must take three parts of the hard Metal, to two parts of Mercury: If you would have it so soft as to spread, you must take two or three parts of Mercury, to one part of the hard Metal.

Detonation, is a Noise that is made, when the Sulphureous Parts of any Mixture  rush forth with Impetuousity; it’s also call’d Fulmination.
Digestion, is some Matter put into a Menstruum, to infuse in a gentle Heat.
Distillation per Ascensum, is when the Fire is to be made under that which is to be distilled.
Distillation per Descensum, is when the Matter which is to be distilled, is placed under the Fire, by which the Spirits are precipitated and forc’d downwards.
Dissolution, is to reduce any hard Body into a Liquor, by the help of a proper Menstruum.
Edulcorate, is to sweeten, or make insipid, some Matter which is impregnated with Salts, by washing it with distilled or Fountain-Water.
Effervescency, is the Ebullition of Liquor, or when two Liquors or a contrary nature are put together, which cause Ebullitions without separating the parts.
Fermentation, is an Ebullition raised by Spirits that endeavour to separate themselves from the Body, but meeting with Earthy Parts that oppose their Passage they swell, and rarefy the Liquor, till they find their way out. In this Separation of Parts, the Spirits divide in such a manner, as to make the Matter of another nature, than it was before.
Filtration, is to purify a Liquor by passing it through a brown Paper; or by laying Stripes of Cotton or Woollen in the Vessel (which contains the foul Water) to the middle of the Stripes, the other Ends hanging over the Vessel, which receives the filtred Liquor.

Rectification, is to distill Spirits after their first Distillation, in order to separate from them such Heterogeneous Matters as have risen with them in their first Distillations.
Reverberation, is to make the Flames of the Fire beat upon the Matter which is reverberated.
Revification, is to reduce any Preparation of Mercury into its Form again.
Sublimation, is to elevate any Volatile Matter into the upper part of such Vessels as contain them, by heat of Fire.
Stratification, is to lay two different things, Bed upon Bed, or Lay upon Lay, one over another.
Precipitation, is to make any Matter dissolved, fall to the bottom of the Vessel, by putting something into the Disolution, which is more agreeable to the Menstruum.’
