An admirable way to preserve Arms from rusting, and take off the rust.

Take a pound and half of Beef Suet, a pound and half of Oyl of sweet Almonds extracted without Fire, one pound of fresh∣ned Olive Oyle, four ounces of Camphire, twelve ounces of Lead burnt with Sulphur, make a Composition of them, and boil it to the substance of an Oyntment, with which rub the Armes to prevent rusting.

Note, that Lead is burnt by melting, and then throwing upon it powdered Sulphur, al∣ways stirring the Lead with an Iron Rod, till it remains in a black Powder. Olive Oyle is freshned with luke-warm Water, beating them together, and then letting them settle again; lastly, put them into a Funnel to filtrate, the Water will run out first when you unstop the bottom hole.
