iipwards, and cover it with a plate of Iron, almost red hor, and press it bard: ciit ofthe sides there will be expressed an Oyl of a yellow colour, and stinking of burning*which is good for the fame purposes ; that which is good to refresh decayed spirits,is prepared another way.

How to extraCl Ojl by Descent.

T He way is common and vulgar to all; for it is done by Ustulation: but theOyls are of a most offensive favor, and can be used only in outward Medicines;for they are not to be taken inwardly. Prepare a Pipkin made of tough Llay, andable to endure fire, well vernifhed within, that there may be no iufpicion of runningout : let the bottom be full of holes, set upon another earthen Pipkin , whosemouth is large enough to receive the bottom of the upper Pipkin ; lute them cloie to-gether* Fill the Pipkin with slices of your Wood : cover it, and lute it. 1 hendig a hole, and let the Pipkins into it, and sting in the Earth about it , and tread icdown close , and throw Sand over it two inches thick : make a gentle fire just o-ver the Pipkin ; which you must encrease by degrees, until the Pipkin have stoodthere a whole day. After this,r move the fire j and when the heat is spent, dig upthe Pipkins , and you will finde the Oyl strained down into the lower ; which youmust distil again in a Retort, to purifie it from filth. To add something to the for-mer inven'ion, I always do thus: I make aTrcffel with Legs of two foot in length.There must a hole be bored in the Plank of it, to receive the neck of the Limbeck.Upon the Tressel fasten an Iron-plate to keep the Wod from burning. Un-derneath , about the middle of the Feet, fasten a Board , upon which the Re-ceiver may stand, and meet with the neck of the inverfed Vessel; which being filledwith the materials to be stilled , kindle a fire about it. Therefore if you wouldextract

Oyl out of hignum (juttiaettm ,

fill it with the Dust of Lignum Guaiacum, and lute it close with Straw-Morrar, twicecr thrice double: when it is dried in the Sun, pur into the neck, wire Strings, andthrust it through the hole of the Tressel into the mouth of the Receiver, and mor-tar them together. Then kindle the fire on the Plate abouc the body of the Lim-beck, at some distance at first, and by degrees nigher and hotter: but let it not be redhot, until you think it be all burned: then remove the fire , and let it rest a while,Until it be cold, and you (hall firde in the lower Vessel a black stinking burnt Oyl. Inthis manner is Oyl drawn out of juniper, Cypress, and Lignum Aloes : but in thislast, you must use more Art and diligence, and a gentle fire, because it is mixed inOytu aients.

Of the Extraction if Essences.

have delivered the several kiifdes of Extraction of Oyls , now we arecome to Quint ss-nccs, the Extraction of which, we will here de-clare. The Paracellun^ define a Quintessence to be the Form, or Spirit, or Ver-tue, or Life, separated worn the cross and elementary impurities of the Body. Icall it the Life , because it cannot be extracted out of the Bones, Flesh, Marrow,Blood, and other Members: for wanting Life, they want also the Quintessence. Ifay , Separated ftorti elementary impurities, because When the Quintessence is ex-tracted, there remaineth only a mass of Elements void of all power: for the Power,Vertue, and Mtdicinable qualities, are not the Elements, but in their Essences,which yet are figments,and contain the vercue of the Elements in them,in the high-est degree* for being separated from the gtosness of their bodies,they become spiritu-al, and par forth their power more effectually and strongly when they arc freed front
